1.25G BIDI SM SFP SC 160KM 120KM 80KM 0KM 40KM 61490nm 1550nm Gigabit Optical Transceiver Module

Description

The 1.25G BIDI SFP is a high performance, cost effective modules, which is supporting up to 1.25Gbps, and transmission distance up to 160km on SM fiber. The transceiver consists of two sections: The transmitter section incorporates a laser driver and a 1490nm DFB laser. The receiver section consists of a PIN photodiode integrated with a transimpedance preamplifier (TIA) and a Limitting Amplifier. The module is hot pluggable into the 20-pin connector. The high-speed electrical interface is base on low voltage logic, with nominal 100Ohms 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. This interface uses a single address, A0h, with a memory map divided into a lower and upper area. Basic digital diagnostic (DD) data is held in the lower area while specific data is held in a series of tables in the high memory area.
