Description

Description

FT-MTRA-3E30Ais a high performance, cost effective modules, which is supporting Multi Rate 9.953-25.78Gbps, and transmission distance up to 10km 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 transimpedance preamplifier (TIA), a Limitting Amplifier and CDR. The module is hot pluggable into the 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 LVTTL logic high-level input of TX_DIS. 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 of 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.
