IBM BNT BN-CKM-SP-SR Compatible 10GBASE-SR SFP+ 850nm 300m MMF LC DOM Optical Transceiver Module


IBM BNT BN-CKM-SP-SR compatible optical transceiver is a dual fiber 10.3Gbps Small Form-factor Pluggable SFP+ module for use in 10GBASE Ethernet. SFP+ SR provides 10Gb/s throughput up to 300 meters over OM3 or 82 meters over OM2 multi-mode fiber (MMF) using 850nm wavelength. This transceiver is fully compliant with SFP+ Multi-Source Agreement (MSA), IEEE 802.3ae 10GBASE-SR and SFI standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP+ transceiver features highly reliable VCSEL transmitter and PIN photo detector to offer high performance interconnection at 10 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 IBM BNT BN-CKM-SP-SR transceivers.
