25G SFP28 SR Fiber Optic Transceiver 850nm 100m DOM Transceiver Module
Description
Cisco Juniper Compatible 25G SFP28 SR 850nm 100m DOM Transceiver
Module manufactured by ANC International Co., Limited is designed
for use in 25 Gb/s data rate over multimode fiber. They are
compliant to IEEE 802.3by, SFF-8472 Rev 12.2 and SFF-8402, and
compatible with SFF-8432 and applicable portions of SFF-8431 Rev.
4.1. The optical transceiver is compliant per the RoHS Directive
2011/65/EU.
25G SFP28 SR transceiver is programmed and tested to perform
identical to original Cisco Juniper 25G-SFP28-SR SFP28 transceiver
and provide a cost-effective replacement. It can be used in 25G
SFP28 ports of Cisco or Juniper Fiber Switches, Routers, Line card,
and so on. The SFP28 SR module support max links of 70m over OM3 or
100m over OM4 multi-mode fiber.
The 25Gbps 850nm SFP28 Optical Transceiver is a single-Channel, Pluggable, high performance fiber optic transceiver module. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses duplex LC receptacle. This module incorporates proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
