The FC-LINK SFP+ 10G 50GHz DWDM 40km ER LC DX is a high performance, cost effective module supporting multi rate 9.95Gbps to 11.3Gbps with CDR, 8.5Gbps bypass CDR, and transmission distance up to 40km on SM fiber; the transceiver consists of two sections: transmitter incorporating a laser driver and TTOSA, and receiver with PIN integrated transimpedance preamplifier (TIA); this hot-pluggable module connects via 20-pin connector, featuring high-speed electrical interface based on low voltage logic with nominal 100ohms differential impedance and AC coupling; optical output is disabled by LVTTL high-level TX_DIS input, while Tx_Fault indicates laser-related faults and RX_LOS signals receiver input loss; its serial EEPROM enables monitoring/configuration access via 2-wire SFP management interface using single address A0h, with memory map divided into lower area (storing basic DD data) and upper area housing specific data in high memory tables.
