SFP28 Optical Transceiver CBO SM25G-SR-BO 25 Gbit/s Single-mode

CBO SM25G-SR-BO is an SFP28 optical transceiver module engineered for 25 Gbit/s single-mode fiber links. The module is intended for hot-pluggable installation in network equipment with SFP28 ports such as switches, routers and servers. It supports short-reach single-mode connections and offers a compact form factor designed for high-density deployments in data centers and enterprise networks while maintaining reliable signal integrity for high-speed applications.

Advantages

The transceiver provides a compact, hot-pluggable design that simplifies installation and replacement without powering down the host device. It supports a 25 Gbit/s data rate for single-mode fiber, enabling low-latency, high-throughput links. Built for interoperability with standard SFP28 ports, the module aims to deliver stable optical performance and reduced footprint in rack environments. Passive cooling and standardized electrical/optical interfaces support predictable behavior under typical operating conditions.

Suitable for

• Short-reach single-mode connections in data center top-of-rack switches
• Server uplinks and aggregation ports requiring 25 Gbit/s bandwidth
• High-density network deployments where hot-pluggable modules are required

Key specifications

• Interface: SFP28 form factor compatible with SFP28 ports
• Data rate: 25 Gbit/s
• Fiber type: single-mode fiber
• Reach: designed for short-reach single-mode links
• Optical connector type: duplex LC compatible
• Power consumption: low-profile, passive thermal design suitable for typical switch/server environments
• Hot-pluggable: supports insertion/removal without powering down host equipment

How to use

Insert the SFP28 transceiver into an available SFP28 port on the switch, router or server until it seats securely and the module latch engages. Connect single-mode duplex LC fiber patch cords to the optical ports observing proper transmit/receive orientation. Verify link status via the host device management interface and monitor optical parameters where supported. Remove the module by releasing the latch and pulling the module straight out; handle by the housing and avoid touching fiber endfaces.

Recommendations

Use clean, certified single-mode LC patch cords and confirm fiber polarity before powering network flows. Verify compatibility with the host device’s SFP28 port and consult equipment documentation for supported optical budgets. Store unused modules in protective packaging to avoid contamination and physical damage.
