SFP Block Diagram Overview The AFBR-571xZ family of optical transceivers are compliant with the specifications set forth in the IEEE802.3 (1000BASE-SX) and the Small Form-Factor Pluggable (SFP) Multi-Source Agreement (MSA). This family of transceivers is qualified in accordance with Telcordia GR-468-CORE. Its primary application is servicing Gigabit Ethernet links between optical networking equipment. The AFBR-571xZ offers maximum flexibility to designers, manufacturers, and operators of Gigabit Ethernet networking equipment. A pluggable architecture allows the module to be installed into MSA standard SFP ports at any time – even with the host equipment operating and online. This facilitates the rapid configuration of equipment to precisely the user’s needs – reducing inventory costs and network downtime. Compared with traditional transceivers, the size of the Small Form Factor package enables higher port densities. Module Diagrams Figure 1 illustrates the major functional components of the AFBR-571xZ. The external configuration of the module is depicted in Figure 7. Figure 8 depicts the panel and host board footprints. 2 321 20 VEET 19 321 ENGAGEMENT SEQUENCE 1 VEET TD– 2 TX FAULT 18 TD+ 3 TX DISABLE 17 VEET 4 MOD-DEF(2) 16 VCCT 5 MOD-DEF(1) 15 VCCR 6 MOD-DEF(0) 14 VEER 7 RATE SELECT 13 RD+ 8 LOS 12 RD– 9 VEER 11 VEER 10 VEER TOP OF BOARD BOTTOM OF BOARD (AS VIEWED THROUGH TOP OF BOARD) Figure 2. Pin description of the SFP electrical interface. Installation Transmit Fault (Tx_Fault) The AFBR-571xZ can be installed in or removed from any MSA-compliant Pluggable Small Form Factor port regardless of whether the host equipment is operating or not. The module is simply inserted, electrical-interface first, under finger-pressure. Controlled hot-plugging is ensured by 3‑stage pin sequencing at the electrical interface. This printed circuit board card-edge connector is depicted in Figure 2. A catastrophic laser fault will activate the transmitter signal, TX_FAULT, and disable the laser. This signal is an open collector output (pull-up required on the host board). A low signal indicates normal laser operation and a high signal indicates a fault. The TX_FAULT will be latched high when a laser fault occurs and is cleared by toggling the TX_DISABLE input or power cycling the transceiver. The transmitter fault condition can also be monitored via the 2-wire serial interface (address A2, byte 110, bit 2). As the module is inserted, first contact is made by the housing ground shield, discharging any potentially component-damaging static electricity. Ground pins engage next and are followed by Tx and Rx power supplies. Finally, signal lines are connected. Pin functions and sequencing are listed in Table 2. Transmitter Section The transmitter section includes the Transmitter Optical Subassembly (TOSA) and laser driver circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom IC, which converts differential logic signals into an analog laser diode drive current. This Tx driver circuit regulates the optical power at a constant level provided the data pattern is DC balanced (8B10B code for example). Transmit Disable (Tx_Disable) The AFBR-571xZ accepts a TTL and CMOS compatible transmit disable control signal input (pin 3) which shuts down the transmitter optical output. A high signal implements this function while a low signal allows normal transceiver operation. In the event of a fault (e.g. eye safety circuit activated), cycling this control signal resets the module as depicted in Figure 6. An internal pull-up resistor disables the transceiver transmitter until the host pulls the input low. Host systems should allow a 10ms interval between successive assertions of this control signal. Tx_Disable can also be asserted via the 2-wire serial interface (address A2h, byte 110, bit 6) and monitored (address A2h, byte 110, bit 7). The contents of A2h, byte 110, bit 6 are logic OR’d with hardware Tx_Disable (pin 3) to control transmitter operation. 3 Eye Safety Circuit The AFBR-571xZ provides Class 1 eye safety by design and has been tested for compliance with the requirements listed in Table 1. The eye safety circuit continuously monitors optical output power levels and will disable the transmitter and assert a TX_FAULT signal upon detecting an unsafe condition. Such unsafe conditions can be created by inputs from the host board (Vcc fluxuation, unbalanced code) or faults within the module. Receiver Section The receiver section includes the Receiver Optical Subassembly (ROSA) and amplification/quantization circuitry. The ROSA, containing a PIN photodiode and custom trans-impedance preamplifier, is located at the optical interface and mates with the LC optical connector. The ROSA is mated to a custom IC that provides post-amplification and quantization. Also included is a Loss Of Signal (LOS) detection circuit. Receiver Loss of Signal (Rx_LOS) The Loss Of Signal (LOS) output indicates an unusable optical input power level. The Loss Of Signal thresholds are set to indicate a definite optical fault has occurred (e.g., disconnected or broken fiber connection to receiver, failed transmitter, etc.). The post-amplification IC includes transition detection circuitry which monitors the ac level of incoming optical signals and provides a TTL/CMOS compatible status signal to the host (pin 8). An adequate optical input results in a low Rx_LOS output while a high Rx_LOS output indicates an unusable optical input. The Rx_LOS thresholds are factory-set so that a high output indicates a definite optical fault has occurred. For the AFBR-5715Z family, Rx_LOS can also be monitored via the 2-wire serial interface (address A2h, byte 110, bit 1). Functional I/O Digital Diagnostic Interface and Serial Identification (EEPROM) The AFBR-571xZ accepts industry standard differential signals such as LVPECL and CML within the scope of the SFP MSA. To simplify board requirements, transmitter bias resistors and ac coupling capacitors are incorporated, per SFF-8074i, and hence are not required on the host board. The module is AC-coupled and internally terminated. The entire AFBR-571xZ family complies with the SFF8074i SFP specification. The AFBR-5715Z family further complies with SFF-8472, the SFP specification for Digital Diagnostic Monitoring Interface. Both specifications can be found at http://www.sffcommittee.org. Figure 3 illustrates a recommended interface circuit to link the AFBR-571xZ to the supporting Physical Layer integrated circuits. The AFBR-571xZ features an EEPROM for Serial ID, which contains the product data stored for retrieval by host equipment. This data is accessed via the 2-wire serial EEPROM protocol of the ATMEL AT24C01A or similar, in compliance with the industry standard SFP Multi-Source Agreement. The base EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8074i. Contents of this serial ID memory are shown in Table 10. Timing diagrams for the MSA compliant control signals implemented in this module are depicted in Figure 6. The AFBR-571xZ interfaces with the host circuit board through twenty I/O pins (SFP electrical connector) identified by function in Table 2. The AFBR-571xZ high speed transmit and receive interfaces require SFP MSA compliant signal lines on the host board. The Tx_Disable, Tx_Fault, and Rx_LOS lines require TTL lines on the host board (per SFF-8074i) if used. If an application chooses not to take advantage of the functionality of these pins, care must be taken to ground Tx_Disable (for normal operation). The I2C accessible memory page address 0xB0 is used internally by SFP for the test and diagnostic purposes and it is reserved. 1 µH VCCT,R 10 µF 0.1 µF HOUSING GROUND 1 µH 0.1 µF TX_FAULT VREFR TX[0:9] SO1+ 50 Ω SO1– 50 Ω RBC RX_RATE SYN1 RC1(0:1) RCM0 RFCT RX_LOS TD– 10 µF R LASER DRIVER & EYE SAFETY CIRCUITRY VCCR RD+ C C 50 Ω SI1– VCCT,R 0.1 µF 50 Ω SI1+ RD– AMPLIFICATION & QUANTIZATION REF_RATE *RES *RES *RES *RES RX_LOS MOD_DEF2 MOD_DEF1 MOD_DEF0 REFCLK VEER 125 MHz NOTE: * 4.7 k Ω < RES < 10 kΩ Figure 3.

This new digital diagnostic information is stored in bytes 0-255 at memory address 0xA2.Using the 2-wire serial interface defined in the MSA, the AFBR-5715Z provides real time temperature, supply voltage, laser bias current, laser average output power and received input power. These parameters are internally calibrated, per the MSA. The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Transmitter Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS). The new diagnostic information provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault Isolation and Component Monitoring. Predictive Failure Identification The predictive failure feature allows a host to identify potential link problems before system performance is impacted. Prior identification of link problems enables a host to service an application via “fail over” to a redundant link or replace a suspect device, maintaining system uptime in the process. For applications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics associated with observing laser degradation and predicting failure: average laser bias current (Tx_Bias) and average laser optical power (Tx_Power). Compliance Prediction Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-5715Z devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. Received optical power is also available to assess compliance of a cable plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission. Fault Isolation The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime. For optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an installation. AFBR-5715Z real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can be used to assess local transceiver current operating conditions. In addition, status flags Tx_Disable and Rx Loss of Signal (LOS) are mirrored in memory and available via the two-wire serial interface. Component Monitoring Component evaluation is a more casual use of the AFBR5715Z real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power. Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or field qualification. For example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, PCI cards and systems. Required Host Board Components The MSA power supply noise rejection filter is required on the host PCB to meet data sheet performance. The MSA filter incorporates an inductor which should be rated 400 mADC and 1 Ω series resistance or better. It should not be replaced with a ferrite. The required filter is illustrated in Figure 4. The MSA also specifies that 4.7 K to 10 KΩ pull-up resistors for TX_FAULT, LOS, and MOD_DEF0,1,2 are required on the host PCB. 1 µH VCCT 0.1 µF 1 µH VCCR 0.1 µF SFP MODULE Figure 4.

It is capable of transmission up to 500m with 50/125 µm fiber and up to 300m with 62.5/125 µm fiber, for 1.0625 GBd Fiber Channel. Application Support areas. The ESD sensitivity of the AFBR-571xZ is compatible with typical industry production environments. The second case to consider is static discharges to the exterior of the host equipment chassis after installation. To the extent that the optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level ESD requirements. To assist in the transceiver evaluation process, Agilent offers a 1.25 Gbd Gigabit Ethernet evaluation board which facilitates testing of the AFBR-571xZ. It can be obtained through the Agilent Field Organization by referencing Agilent part number HFBR-0571. Electromagnetic Interference (EMI) A Reference Design including the AFBR-571xZ and the HDMP-1687 GigaBit Quad SerDes is available. It may be obtained through the Agilent Field Sales organization. The metal housing and shielded design of the AFBR571xZ minimize the EMI challenge facing the host equipment designer. Regulatory Compliance EMI Immunity See Table 1 for transceiver Regulatory Compliance. Certi fication level is dependent on the overall configuration of the host equipment. The transceiver performance is offered as a figure of merit to assist the designer. Equipment hosting AFBR-571xZ modules will be subjected to radio-frequency electromagnetic fields in some environments. The transceiver has excellent immunity to such fields due to its shielded design. Electrostatic Discharge (ESD) Flammability The AFBR-571xZ exceeds typical industry standards and is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 1. The AFBR-571xZ transceiver is made of metal and high strength, heat resistant, chemically resistant, and UL 94V-0 flame retardant plastic. There are two design cases in which immunity to ESD damage is important. Customer Manufacturing Processes The first case is during handling of the transceiver prior to insertion into the transceiver port. To protect the transceiver, it’s important to use normal ESD handling precautions. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled 6 Equipment using the AFBR-571xZ family of transceivers is typically required to meet the requirements of the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe, and VCCI in Japan. This module is pluggable and is not designed for aqueous wash, IR reflow, or wave soldering processes. Table 1.

TX Fault is an open collector/drain output which should be pulled up externally with a 4.7KΩ – 10 KΩ resistor on the host board to a supply <VccT+0.3 V or VccR+0.3 V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. 2.

They should be pulled up with a 4.7-10 KΩ resistor on the host board to a supply less than VccT +0.3 V or VccR+0.3 V. Mod-Def 0 is grounded by the module to indicate that the module is present Mod-Def 1 is clock line of two wire serial interface for optional serial ID Mod-Def 2 is data line of two wire serial interface for optional serial ID 4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 KΩ resistor on the host board to a supply < VccT,R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operatio0n. In the low state, the output will be pulled to < 0.8 V. 5. RD-/+: These are the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω differential at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines must be between 370 and 2000 mV differential (185 – 1000 mV single ended) according to the MSA. Typically it will be 1500mv differential. 6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 – 3.465 V at the SFP connector pin. The in-rush current will typically be no more than 30 mA above steady state supply current after 500 nanoseconds. 7. TD-/+: These are the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 – 2400 mV (250 – 1200 mV single ended). However, the applicable recommended differential voltage swing is found in Table 5. 8 Table 3.
