25G SFP28 ER SM 1310nm 40km Fiber Optic Transceiver Cisco Compatible
Description
25G SFP28 ER single-mode transceiver is SFP28 module for duplex optical data communications support up to 28.05Gb/s. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has built-in clock and data recovery (CDR). This module is designed for single-mode fiber. It can be Cisco, Juniper, Brocade, HW etc compatible.
ANC 25G Transceivers include SFP28-SR, SFP28-LR, SFP28-ER, SFP28-BIDI, SFP28-CWDM and SFP28-DWDM
It offers connecting solution from 100m to 40km for data centers, high speed network and 5G. 25G SFP28 comes from the fact that it is a Small Form-factor Pluggable (SFP) and its electrical interface can handle a channel of 25G, potentially up to 28G.
