SFP28 transceiver CBO SFP28-25G-LR-SS-BO 25 Gbit/s LC single-mode 10,000 m

CBO SFP28-25G-LR-SS-BO is a 25 Gbit/s SFP28 optical transceiver with an LC duplex connector designed for single-mode fiber links up to 10,000 m. The module supports 25G Ethernet and other 25 Gbit/s serial optical interfaces, offering long-reach connectivity for switches, routers and optical line cards. It is powered and initialized through a standard SFP28 interface and supports hot-plug installation for straightforward deployment in compatible network ports.

Advantages

The module delivers 25 Gbit/s line-rate performance with low latency and stable optical output suitable for long-distance fiber runs. Its single-mode design and LC connector provide compatibility with common fiber infrastructures while optimizing reach up to 10 km. The compact SFP28 form factor reduces port density constraints and allows easy insertion and removal without system downtime. Built to industry electrical and optical specifications, the transceiver enables predictable behaviour in multi-vendor networks.

Suitable for

• 25G Ethernet uplinks between switches and aggregation devices
• Long-distance connections in data center interconnects and campus backbones
• High-speed links in routers, firewalls and optical transceivers supporting 25G
• Replacement or expansion of existing single-mode LC fiber ports

Key specifications

How to use

Insert the SFP28 transceiver into a compatible SFP28 slot on the network device until it latches. Connect the LC duplex single-mode fiber cable, ensuring correct TX/RX orientation and clean fiber endfaces to maintain optical performance. After installation the host device will detect and power the transceiver; verify link status and diagnostic readings via the device management interface. For replacement, power down procedures are generally not required due to hot-pluggable capability, but follow your equipment vendor's guidance for safe handling.

Recommendations

Use APC- or UPC-terminated single-mode fiber with appropriate attenuation and cleaning to avoid signal loss. Verify compatibility with the host device's supported 25G interface list and monitor optical power and temperature via management tools to ensure reliable long-reach operation.
