The QSFP-40G-ER4 (Quad Small Form-factor Pluggable 40G Extended Reach) is a hot-swappable, optical fiber transceiver module. It's designed for long-haul communications, transmitting 40Gbps data rates over single-mode fiber (SMF) for distances up to 40 kilometers. The new DQ+BC0003-DS+ 3m QSFP56 break-out cable replaces XQ+BC0003-XS+ at the same price, adding support for 200G to 4×50G splitting while retaining compatibility. Our 40GBASE-ER4 QSFP+ transceiver enables ultra-long-reach connectivity for service provider networks. 40G QSFP ER4 optical transceiver module, support 40Gb/s and up to 40 km transmission on SM fiber, it works in high-speed IDC connection solutions, and so on. Features 4 CWDM lanes MUX/DEMUX design Up to 11. 2Gbps per channel bandwidth Aggregate bandwidth of > 40Gbps Duplex LC connector Compliant. The L-com FXC-SFP1G-31-40 is an SFP form-factor transceiver, supporting Gigabit Ethernet data rates. It uses fiber optical technology to send and receive data through completing the process of optical signal – electrical signal / electrical signal – optical signal conversion.
