Optický SFP28 modul CBO SFP28-25G-ESR-LE-BO 25 Gbit/s LC 300 m

The Fiber optic SFP28 module CBO SFP28-25G-ESR-LE-BO is a single-lane 25 Gbit/s transceiver with an LC duplex connector designed for short-reach fiber links up to 300 m. Intended for installation in SFP28-compatible switches, routers and servers, this module provides a compact hot-pluggable interface for high-density network environments. The module supports low-latency, high-throughput connections for data center top-of-rack, aggregation and enterprise access layers while maintaining compatibility with standard single-mode or specified multimode fiber plants as required.

Advantages

This SFP28 transceiver delivers a 25 Gbit/s data rate in a small form factor that fits standard SFP28 ports, enabling efficient use of switch and router density. The LC duplex interface offers widespread compatibility with existing fiber cabling. With a maximum reach of 300 m, the module is suitable for short-range links inside data centers and campus buildings. Hot-pluggable design simplifies installation and replacement without powering down equipment, and the module is engineered for stable operation with low latency, supporting demanding network traffic patterns.

Suitable for

• Short-reach 25 Gbit/s links in data centers and server rooms
• Top-of-rack and aggregation switch connections
• High-density network deployments requiring hot-swap capability
• Enterprise campus interconnects over short fiber runs

Key specifications

• Nominal data rate: 25 Gbit/s (single lane)
• Connector type: LC duplex
• Maximum reach: up to 300 metres over suitable fiber
• Form factor: SFP28 (hot-pluggable)
• Typical application: short-range optical links for switches, routers and servers

How to use

Insert the SFP28 module into an empty SFP28 port on a compatible switch, router or server until it clicks into place. Connect LC duplex fiber cable, ensuring correct transmit/receive orientation and proper fiber type for the required reach. After physical installation the host device should recognise the transceiver and negotiate link parameters automatically; verify link status and operational speed via the device management interface. To remove, disengage any retention latch and pull the module straight out while the host device is powered according to manufacturer guidance.

Recommendations

Use LC duplex fiber patch cords of appropriate specification and maintain clean connector endfaces to ensure reliable performance. Match fiber type and cable attenuation to the 300 m range requirement, and follow equipment vendor compatibility lists when deploying SFP28 modules in multi-vendor environments.
