Multi-rate Gigabit Ethernet & FibreChannel SFP CWDM Transceivers with Digital Diagnostics TRPAG1M CWDM MR The TRPAG1M CWDM SFP series of multi-rate fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for 1000BASE-LX Gigabit Ethernet and 1.062GBd Fibre Channel applications. The transceivers are designed to support data rates ranging from 1.25Gb/s down to 125Mb/s. Diagnostics monitoring functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8472, Rev. 9.3. There are eight center wavelengths available: 1471nm, 1491nm, 1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm. Two optical link power budget options are offered, YX (22dB minimum) and ZX (24dB minimum). They correspond to transmission distances of 62km and 70km, respectively (assuming a total connector/splice/ CWDM mux and demux loss of 4.5dB, allocated system penalty of 2dB and fiber loss of 0.25dB/km). All modules satisfy Class I Laser Safety requirements in accordanc with the U.S. FDA/ CDRH and international IEC-60825 standards. The TRPAG1M CWDM transceivers connect to standard 20-pad SFP connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different types of transceivers without removing the power supply from the host system. The transceivers have colored bail-type latches, which offer an easy and convenient way to release the modules. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are ACcoupled internally. LVTTL Transmitter Disable control input and Loss of Signal output interfaces are also provided. The transceivers operate from a single +3.3V power supply over operating case temperature range of -5°C to +70°C (“B” option) or -5°C to +85°C (“E” option). The housing is made of plastic and metal for EMI immunity.

The high speed DATA interface is differential AC-coupled internally with 0.1μF and can be directly connected to a 3.3V SERDES IC. All low speed control and sense output signals are open collector TTL compatible and should be pulled up with a 4.7 - 10kΩ resistor on the host board and MOD_DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol (standard two-wire I2C serial interface) and generates the serial clock signal (SCL). The positive edge clocks data into the EEPROM segments of the SFP that are not write protected, and the negative edge clocks data from the SFP. The serial data signal (SDA) is for serial data transfer. The host uses SDA in conjunction with SCL to mark the startand end of serial protocol activation. The supported monitoring functions are internal temperature, supply voltage, bias current, transmitter power, average receiver signal, all alarms and warnings and software monitoring of TX Fault/LOS. The device is internally calibrated. Loss of Signal (LOS): The Loss of Signal circuit monitors the level of the incoming optical signal and generates a logic HIGH when an insufficient photocurrent is produced. TX_Fault: The output indicates LOW when the transmitter is operating normally, and HIGH with a laser fault including laser end-of-life. TX Fault is an open collector/drain output that should be pulled up with a 4.7 - 10kΩ resistor on the host board. TX Fault is latched per SFP MSA. The data transfer protocol and the details of the mandatoryand vendor specific data structures are defined in the SFPMSA, and SFF-8472, Rev. 9.4 TX_Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -45dBm). Power supply and grounding: The power supply line shouldbe well-filtered. All 0.1μF power supply bypass capacitors should be as close to the transceiver module as possible. Serial Identification and Monitoring: The module definition of SFP is indicated by the three module definition pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Upon power up, MOD_DEF(1:2) appear as NC (no connection), Oplink Communications, Inc. 4 RevB-P. 2009.04.01 TRPAG1M CWDM MR 6335 Landing Pkwy Fremont, CA 94538 Tel: (510) 933-7200 Fax: (510) 933-7300 Email: [email protected] • www.oplink.com Mechanical Package Dimensions in inches [mm] Default tolerances: .xxx = + .005”, .xx = + .01” Ordering Information Model Name Operating Temperature Nominal Wavelength (nm) Latch Color TRPAG1ZXIBAM1 - 5°C to +70°C 1471 Gray TRPAG1YXHBVM2 TRPAG1ZXIBVM2 - 5°C to +70°C 1491 Violet TRPAG1YXHBBM3 TRPAG1ZXIBBM3 - 5°C to +70°C 1511 Blue TRPAG1YXHBGM4 TRPAG1ZXIBGM4 - 5°C to +70°C 1531 Green TRPAG1YXHBYM5 TRPAG1ZXIBYM5 - 5°C to +70°C 1551 Yellow TRPAG1YXHBOM6 TRPAG1ZXIBOM6 - 5°C to +70°C 1571 Orange TRPAG1YXHBRM7 TRPAG1ZXIBRM7 - 5°C to +70°C 1591 Red TRPAG1YXHBNM8 TRPAG1ZXIBNM8 - 5°C to +70°C 1611 Brown TRPAG1YXHEAM1 TRPAG1ZXIEAM1 - 5°C to +85°C 1471 Gray TRPAG1YXHEVM2 TRPAG1ZXIEVM2 - 5°C to +85°C 1491 Violet TRPAG1YXHEBM3 TRPAG1ZXIEBM3 - 5°C to +85°C 1511 Blue TRPAG1YXHEGM4 TRPAG1ZXIEGM4 - 5°C to +85°C 1531 Green TRPAG1YXHEYM5 TRPAG1ZXIEYM5 - 5°C to +85°C 1551 Yellow TRPAG1YXHEOM6 TRPAG1ZXIEOM6 - 5°C to +85°C 1571 Orange TRPAG1YXHERM7 TRPAG1ZXIERM7 - 5°C to +85°C 1591 Red TRPAG1YXHENM8 TRPAG1ZXIENM8 - 5°C to +85°C 1611 Brown 22dB Link Budget Color (62km Distance)1 24dB Link Budget (70km Distance)1 TRPAG1YXHBAM1 The indicated transmission distance is for guidelines only, not guaranteed.
