Product information

Description

CBO SFP28-25G-ESR-AR-BO is a 25 Gbit/s optical SFP28 transceiver designed for short-reach multimode fiber links. The module supports 25GBase-SR operation over multimode fiber to distances up to 300 m and uses an LC duplex connector in a hot-pluggable SFP28 form factor, enabling straightforward upgrades in switches, routers and server network interfaces. The transceiver is intended for high-density installations where compact size and compatibility with standard SFP28 ports are required.

Advantages

The transceiver provides 25 Gbit/s data rate in a compact SFP28 package, supporting short-reach multimode fiber links with an LC connector for common cabling infrastructures. Its hot-pluggable design allows replacement or upgrades without powering down equipment. The module is suitable for high-density rack environments and supports standard 25GBase-SR optical signaling for interoperability with compatible networking equipment.

Suitable for

  • Data center server uplinks and top-of-rack switch connections
  • Aggregation links within racks and between nearby racks
  • High-speed interconnects in campus and enterprise networks using multimode fiber
  • Upgrading 10G links to 25G where short-reach multimode fiber is available

Key specifications

  • Data rate: 25 Gbit/s (25GBase-SR)
  • Fiber type: Multimode fiber (MMF)
  • Maximum reach: Up to 300 m on appropriate multimode fiber
  • Connector type: LC duplex
  • Form factor: SFP28, hot-pluggable
  • Optical type: Short-reach (SR) multimode transceiver

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch, server NIC or router while the host device is powered according to the equipment manufacturer’s hot-swap guidelines. Connect LC duplex multimode fiber patch cords to the module and to the corresponding port on the remote device, observing correct transmit/receive orientation. After insertion, verify link status and speed through the host device management interface or LEDs. Use diagnostic and monitoring features provided by the host to confirm optical levels and link quality if available.

Usage recommendations

Use OM3/OM4 multimode fiber and high-quality LC patch cords to achieve the specified reach and performance. Follow equipment vendor compatibility lists when planning upgrades and perform link testing after installation to ensure correct operation. Avoid exposing the optical interfaces to dust and keep protective caps on when modules are not connected.
