SFP MODULE BIDI 1.25G 1550-1310nm 40km (PAIR)

NL-GE-B35L/S-40D is a high performance, cost effective modules, which is supporting up to 1.25Gbps, and transmission distance up to 40km on SM fiber. The transceiver consists of two sections: The transmitter section incorporates a laser driver and a 1310nm DFB laser. The receiver section consists of a PIN photodiode integrated with a transimpedance preamplifier (TIA) and a Limiting Amplifier. The module is hot pluggable into the 20-pin connector. The high-speed electrical interface is base on bw voltage logic, with nominal 1000hms differential impedance and AC coupled in the 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 faun condition related to laser operation or safety. I oss of signal (RX_LOS) output is provided to indicate the loss of an input optical signal of receiver. A serial EEPROM in me
transceiver allows the user to access transceiver monitoring and configuration data via the 2-wire SFP Management Interface. This interface uses a single address, AOh, with a tnemory map divided into a lower and upper area. Basic digital diagnostic (DD) data is held in the bwer area while specific data is held in a series of tables in the high memory area.
