Description
This transceiver is a high performance,cost effective modules,which is supporting up to10.3125Gbps,and transmission distance up to 40km on SM fiber.The transceiver consists of two sections:The transmitter section incorporates a laser driver and a1330nm DFB laser.The receiver section consists ofaPIN photodiode integrated with a transimpedance preamplifier(TIA)and a Limitting Amplifier.The moduleis hot pluggable into the 20-pin connector.The high-speed electrical interface is base on low voltage logic,with nominal100Ohms differential impedance and AC coupled in the module.
The optical output can be disabled by LVTTLlogic high-level input ofTX_DIS.Transmit Fault(Tx_Fault)isprovided to indicate that the module transmitter has detected a fault condition related to laser operation orsafety.Loss of signal(RX_LOS)output is provided to indicate the loss of an input optical signal ofreceiver.Aserial EEPROM in the transceiver allows the user to access transceiver monitoring and configuration data viathe 2-wire SFPManagement Interface.This interface uses a single address,A0h,with a memory map dividedinto a lower and upper area.Basic digital diagnostic(DD)data is held in the lower area while specific data isheld in a series of tables in the high memory area.
