Generic Compatible SFP-25G-LWDM1295-ER 25GBASE-LWDM SFP28 1295.56nm 40km SMF LC DOM Optical Transceiver Module
direcXource's SFP-25G-LWDM1295-ER optical transceiver is a dual fiber 25.8Gbps Small Form-factor Pluggable SFP28 LWDM module for use in 25GBASE Ethernet. SFP28 LWDM1295-ER provides 25Gb/s throughput up to 40km over single-mode fiber (SMF) with host FEC using 1295.56nm wavelength. This transceiver is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3 25GBASE-LWDM 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 LAN-WDM EML 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 generic MSA transceivers.
