Cisco CWDM-SFP25G-1270-40 Compatible 25GBASE-CWDM SFP28 1270nm 40km SMF LC DOM Optical Transceiver Module


Cisco CWDM-SFP25G-1270-40 compatible optical transceiver is a dual fiber 25.8Gbps Small Form-factor Pluggable SFP28 CWDM module for use in 25GBASE Ethernet. SFP28 CWDM1270-ER provides 25Gb/s throughput up to 40km over single-mode fiber (SMF) with host FEC using 1270nm wavelength. This transceiver is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3 25GBASE-CWDM and 25GAUI standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP28 transceiver features highly reliable CWDM DML transmitter and APD photo detector to offer high performance interconnection at 25 Gbps data rate. Built-in Digital Diagnostic Monitoring (DDM) support is present for real-time performance monitoring via 2-wire Interface (TWI/I2C). Our modules are factory pre-programmed for compatibility, perform identically to original Cisco CWDM-SFP25G-1270-40 transceivers.
