Cisco SFP-25G-LR-S Compatible 25GBASE-LR SFP28 25G 1310nm 10km DOM Duplex LC/UPC SMF Ethernet Optical Transceiver Module

The SFP-25G-LR SFP28 transceiver provides 25GBase-LR throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via an LC duplex connector. The SFP28 transceiver works on the same 10G network cabling Infrastructure, boosting speed by at least 2.5 times. It also features DDM/DOM for real-time monitoring of operating status. This hot-swappable transceiver is pre-programmed, uniquely serialized, and tested for data traffic and application performance. Besides, it offers interoperability, laying a foundation for the next-generation network upgrade. Each SFP28 transceiver module is individually tested in targeted switch, it is fully compliant with the SFP28 MSA, CPRI and eCPRI standard. Featuring low power consumption, high speed, this 25G transceiver is ideal for 25G Ethernet, telecom, and data center.
