Gigabit Ethernet 850nm Multimode SFP Transceivers With Digital Diagnostics TRPUG1ESXx000E2G Pb Product Description The TRPUG1ESX-E2G fiber optic transceiver with integrated digital diagnostics monitoring functionality provides a quick and reliable interface for 1000BASE-SX Gigabit Ethernet applications. The diagnostic functions, alarm and warning features as described in the Multi-Source Agreement (MSA) document, SFF-8472 (Rev.9.5), are provided via an I2C serial interface. The module satisfies Class 1 Laser Safety requirements in accordance with the U.S.FDA/CDRH and international IEC-60825 standards. The transceiver connects to a 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 transceiver has a bail-type latch, which offers an easy and convenient way to release the modules. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are AC-coupled internally. LV-TTL 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 ranges of -5°C to +70°C (Commercial), -5°C to +85°C (Extended) or -40°C to +85°C(Industrial) . The housing is made of 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 should be pulled up with a 4.7 - 10kΩ resistor on the host board. TX Fault is non-latching (automatically deasserts when fault goes away). TX_Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled. 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). Loss of Signal (LOS): The Loss of Signal circuit monitors the level of the incoming optical signal and generates logic HIGH when an insufficient photocurrent is produced. Upon power up, MOD_DEF(1:2) appear as NC (no connection), and MOD_DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol (standard twowire I2C serial interface) and generates the serial clock signal 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 Oplink Communications, LLC 4 S0487, Rev.01. (web) 2015-04-15 TRMUG1ESXx000E2G (SCL).

The device is internally calibrated. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in SFP MSA, and SFF-8472, Rev. 9.5. The serial data signal (SDA) is for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The supported monitoring functions are temperature, voltage, bias current, transmitter power, average receiver signal, all alarms and warnings, and software Power supply and grounding: The power supply line should be well-filtered. All 0.1µF power supply bypass capacitors should be as close to the transceiver module as possible. 46335 Landing Pkwy Fremont, CA 94538 Tel: (510) 933-7200 Fax: (510) 933-7300 Email: [email protected] • www.oplink.com Mechanical Package R: 4.7 to 10kΩ CAP Values in μF Ordering Information Oplink Part Number Temperature Nominal Wavelength Distance Latch Color TRPUG1ESXE000E2G - 5°C to +85°C 850nm 550m Beige TRPUG1ESXI000E2G - 40°C to +85°C 850nm 550m Beige TRPUG1ESXC000E2G - 5°C to +70°C 850nm 550m Beige The indicated transmission distance is for guidelines only, not guaranteed, The exact distance is dependent on the fiber loss, connector and splice loss, and allocated system penalty.
