SFP28 25 Gbit/s multimode transceiver CBO SFP28-25G-SR-QN-BO LC UPC 25000 Mbit/s

The BlueOptics SFP28 25Gbps Multimode Transceiver (LC UPC) is a compact, hot-pluggable optical module designed for short-reach 25 Gigabit Ethernet links. Built in the SFP28 form factor, it delivers 25,000 Mbit/s throughput over multimode fiber and is suited to high-density installations where reliable, low-latency uplinks and server interconnects are required. The module uses an LC UPC connector and supports standard multimode OM3/OM4 deployments for data center and enterprise network environments.

Advantages

This SFP28 multimode transceiver offers a combination of compact SFP28 form factor compatibility and hot-pluggable convenience for easy installation and replacement. It provides consistent 25Gbps optical performance for short-reach links and is optimized for high-density racks and switches. The LC UPC interface ensures stable optical mating and low reflectance, while the module’s design supports interoperability with standard network equipment that accepts SFP28 multimode modules.

Suitable for

• Short-reach 25 Gigabit Ethernet uplinks in data centers
• Top-of-rack and end-of-row switch connections
• Server-to-switch high-speed interconnects
• Enterprise network aggregation and distribution links

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: Multimode fiber (suitable for OM3/OM4)
• Connector: LC UPC duplex
• Form factor: SFP28 (hot-pluggable)
• Reach: short-reach multimode links (typical within data centre distances)
• Application: 25 Gigabit Ethernet (25GbE)

How to use

Install the transceiver into an SFP28-compatible port on a switch, router or server while the host device is powered on, using hot-pluggable insertion. Ensure the LC UPC duplex patch cable is correctly aligned and securely connected. Verify link status and speed via the host device’s interface or management system and confirm that the transceiver firmware and the network equipment settings support 25GbE multimode operation.

Recommendations

Use quality multimode LC UPC patch cables rated for OM3/OM4 to achieve the expected short-reach 25Gbps performance. Ensure proper cleaning of fiber connectors before mating to reduce insertion loss. For optimal reliability in high-density deployments, monitor port temperatures and use compatible SFP28 ports that explicitly support 25GbE multimode transceivers.
