Fiber optic SFP28 transceiver CBO SFP28-25G-LR-GM-BO 25 Gbps LC Single‑mode 10 km

The BlueOptics CBO SFP28-25G-LR-GM-BO is a fiber optic SFP28 transceiver module designed for 25 Gbps single‑mode links. It fits standard SFP28 cages and delivers LR (long reach) single‑mode transmission up to 10 km over LC duplex fiber. The module is intended for use in high‑speed uplinks, aggregation ports and interconnections between switches, routers and servers where low-latency 25 G connectivity and long reach are required.

Advantages

This transceiver supports a 25 Gbit/s data rate with single‑mode optics optimized for long reach, providing a balance of bandwidth and distance for metropolitan and data center interconnects. The LC duplex interface ensures compatibility with existing single‑mode patching, and the SFP28 form factor offers direct compatibility with equipment supporting 25 G SFP28 ports. The module’s specifications are suitable for low-latency applications and for replacing or upgrading 10 G links to 25 G where longer reach is needed.

Suitable for

• 25 G uplinks between switches in data centers
• Aggregation links in carrier and metro networks
• Server connectivity requiring 25 G long‑reach links
• Inter‑site fiber connections up to 10 km

Key specifications

• Form factor: SFP28
• Data rate: 25 Gbit/s
• Fiber type: single‑mode
• Connector: LC duplex
• Maximum reach: 10 km over single‑mode fiber
• Wavelength: long‑reach optics (LR)
• Use case: uplink and aggregation ports for switches, routers and servers

How to use

Insert the SFP28 transceiver into a compatible SFP28 slot on the switch, router or server until it latches. Connect LC duplex single‑mode patchcords ensuring correct transmit/receive orientation. Verify link status and speed on the host device and configure the port for 25 G operation if required by the system. Observe proper handling of the optical interfaces: keep dust caps on when not in use and clean connectors before mating to maintain signal integrity.

Recommendations

Use single‑mode LC duplex patchcords rated for 10 km or greater, follow vendor guidance for supported firmware and compatibility lists, and avoid bending fiber beyond recommended minimum bend radius. For reliable performance, monitor link optical levels and replace connectors or cables showing persistent attenuation or physical damage.
