ZTE 25G 1310nm SM 300m I-temp SFP28 LR Lite Transceiver Module MTRA-3E11A

The ZTE 033031100002 is a high performance, cost effective modules, which is supporting Multi Rate 9.83~25.78Gbps, and transmission distance up to 300m on SM fiber. The transceiver consists of two sections the transmitter section incorporates a 1310nm DFB Laser, a driver and a CDR. The receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA), a Limiting Amplifier and CDR. The module is hot pluggable with a 20-pin connector. The high-speed electrical interface is base on low voltage logic, with nominal 100 Ohms differential impedance and AC coupled in the module.

The optical output can be disabled by the LVTTL logic high-level input on TX_DIS pin. Transmit Fault (Tx_Fault) is provided to indicate that the module transmitter has detected a fault condition related to laser operation or safety. Loss of signal (RX_LOS) output is provided to indicate the loss of an input optical signal in receiver. 

A serial EEPROM in the transceiver allows the user to access transceiver monitoring and configuration data via the 2-wire SFP Management Interface. Digital diagnostics function are available via a 2-wire serial interface, as specified in SFF-8472.
