1.25G BIDI SM SFP SC 160KM 80KM 1490nm 1550nm Gigabit Optical Transceiver Module

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.
