Description
SFP-1G-1550-200D-l is a high performance, cost effective modues, which is supporting up to 1.25Gbps, and transmission distance up to 200km on SM fiber. The transceiver consists of two sections:The transmitter section incorporates a laser driver and a 1550nm DFB laser. The receiver section consists of a PIN photodiode integrated with a transimpedance preamplifer (TIA)and a Limitting Amplifier. The module is hot pluggable into the 20-pin comnector. The high-speed electrical interface is base on low voltage logic, with nominal 1000hms differential impedance and AC coupled in the module.
The optical output can be disabled by LVTTL logic high-evel 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 confguration data via the 2-wire SFP Management Interface. This interface uses a single address, AOh, 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.
