25G SFP28 LR SM 1310nm 10km Fiber Optic Transceiver For Industrial Temperature
Description
25G SFP28 LR single-mode 1310nm 10km transceiver is SFP28 module for duplex optical data communications support up to 25.78Gb/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 25G SFP28 LR optics module features a highly reliable 1310nm DFB transmitter and PIN photo-detector into duplex LC optical connector, providing links up to 10km over 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.

Notes:
1. Measured with data rate at 25.78Gb/s, BER less than 5E-5 with PRBS 231-1. This value is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.
