SFP28 transceiver CBO SFP28-25G-ESR-IA-BO 25 Gbit/s LC multimode, up to 300 m

CBO SFP28-25G-ESR-IA-BO is an SFP28 optical transceiver module that supports 25 Gbit/s data transmission over multimode fiber with an LC connector. The module is designed for short-reach links up to 300 m and fits standard SFP28 ports for hot-pluggable installation in servers, switches and storage equipment. It implements IEEE-compatible signaling and provides a compact form factor suitable for dense data center and enterprise interconnects.

Advantages

The module delivers a single-lane 25 Gbit/s data rate with stable short-reach optical performance for multimode fiber. Its small SFP28 form factor and hot-pluggable design simplify installation and replacement without powering down equipment. Compliance with common electrical and optical signaling standards ensures interoperability with a wide range of 25 G switches and network devices. The LC duplex interface offers a standard connection method for multimode cabling infrastructures.

Suitable for

• 25 Gbit/s server-to-switch uplinks in data centers
• Top-of-rack and leaf-spine switch connections
• Storage area network links and high-speed interconnects
• Short-reach multimode fiber runs within campus or enterprise sites

Key specifications

• Data rate: 25 Gbit/s single lane
• Optical interface: LC duplex connector
• Fiber type: multimode fiber (MMF)
• Maximum reach: up to 300 meters on suitable multimode fiber
• Form factor: SFP28 hot-pluggable module
• Compatibility: IEEE-aligned signaling for 25 G Ethernet applications

How to use

Insert the SFP28 module into a compatible SFP28 port on a switch, server or storage device until it latches. Connect LC duplex multimode patch cords to the transmit and receive ports following the equipment documentation for port orientation. After insertion, allow the host device to recognize and configure the transceiver; monitor link status LEDs or management interfaces to verify an operational 25 Gbit/s link. To remove, disengage the latch and pull the module straight out, and protect the optical interfaces with dust caps when not connected.

Recommendations

For reliable performance, use the transceiver with multimode fiber of appropriate grade (for example OM3/OM4 where applicable) and maintain clean connectors. Verify that connected equipment supports 25 G SFP28 optics and consult switch firmware compatibility lists if vendor-lock detection is a concern. Avoid exceeding the stated reach and follow standard handling procedures for optical modules to prevent contamination and mechanical damage.
