Transceiver SFP28 CBO SFP28-25G-ESR-CN-BO 25 Gbit/s LC 300 m

CBO SFP28-25G-ESR-CN-BO is a 25 Gbit/s SFP28 optical transceiver with an LC duplex connector and a 300 m effective reach over short-reach multimode fiber. It is designed for use in switches, routers and servers to provide compact, hot-pluggable 25 Gigabit Ethernet or fibre channel links. The module supports straightforward installation and is intended for short-distance high-density data center and enterprise network links.

Advantages

The transceiver offers a small form-factor SFP28 design that preserves port density while enabling 25 Gbit/s throughput. Its LC duplex interface ensures compatibility with common multimode fiber patching infrastructures. The module's plug-and-play operation and industry-standard electrical and optical interfaces allow quick replacement and integration without extensive configuration. Built for short-reach multimode applications, it provides a balance of performance and cost-efficiency for intra-rack and adjacent-rack connections.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and aggregation devices
• Server-to-switch connections in data center and enterprise racks
• Short-reach fibre channel links in storage area networks (SAN)
• High-density multiport environments requiring compact SFP28 modules

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 meters over multimode fiber
• Form factor: SFP28 (small form-factor pluggable)
• Optical interface: short-reach multimode fiber
• Power consumption: typical low-power SFP28 class (refer to device datasheet for exact figures)

How to use

Insert the transceiver into an SFP28-compatible port on a switch, router or server until it latches securely. Connect LC duplex multimode fiber patch cables, ensuring correct transmit-to-receive pairing. After physical installation, verify link status on the host device and confirm negotiated speed of 25 Gbit/s. For replacement, remove the existing module by releasing the latch and pulling straight out, then install the new transceiver following the same steps. Observe electrostatic discharge (ESD) precautions and keep optical interfaces covered when not in use.

Recommendations

Use multimode fiber rated for the specified reach and maintain clean fiber endfaces to preserve optical performance. Confirm compatibility with the host device vendor's supported transceiver list if required by network management policies. Monitor link status and temperature where available, and perform regular inspections of fiber connectors to avoid signal loss caused by contamination or physical damage.
