## Long description

The BlueOptics SFP-10/25G-CSR-S-BO 25000 Mbit/s SFP28 is a small form-factor pluggable fiber optic transceiver module designed for high-speed network links. Compatible with Cisco products and certified to RoHS, CE, FCC and ISO9001 standards, this SFP28 module supports data rates up to 25 Gbit/s and is intended for short to medium reach optical connections. The module's compact SFP28 interface and lightweight nickel-coloured housing make it suitable for dense switch and router installations where space and weight are constrained.
Advantages
The module provides a consistent 25 Gbit/s maximum data transfer rate while maintaining compatibility with common networking equipment. Certifications for RoHS, CE, FCC and ISO9001 indicate compliance with regulatory and quality standards. The SFP28 interface ensures backward-compatible physical fit in SFP28 slots and supports modern high-density port layouts. Its low weight and compact form factor simplify deployment and handling during network upgrades or expansions.
Suitable for
 25 Gbit/s uplinks between switches and routers
 High-density data centre switch ports
 Short- to medium-distance fiber links in campus or enterprise networks
 Replacement or expansion modules in Cisco-compatible equipment

How to use
Insert the BlueOptics SFP28 transceiver into a compatible SFP28 slot on a switch, router or host adapter until it locks into place. Connect the appropriate LC fiber patch cable to the module's optical port, ensuring correct transmitter/receiver orientation. Verify that the connected equipment recognizes the module and negotiates the 25 Gbit/s link; monitor link status via the device management interface. To remove, disengage any retention mechanism and gently pull the module from the slot. Handle the transceiver by its body and keep optical connectors covered when not in use to prevent contamination.
Usage recommendations
Use this SFP28 module with compatible Cisco-certified ports or other equipment that accepts SFP28 transceivers. Match single-mode or multi-mode fiber types and connector types according to link distance and equipment specifications. Keep fiber connectors clean and inspect link operation after installation to confirm expected throughput and signal quality.
