Fiber optic SFP28 transceiver CBO SFP28-25G-ESR-PA-BO, 25 Gbit/s, LC connector, 300 m

BlueOptics SFP28-25G-ESR-PA-BO is a fiber optic SFP28 transceiver module designed for 25 Gbit/s links with an LC duplex connector and a nominal reach of up to 300 m over multimode fiber. The compact, hot-pluggable form factor suits server and switch uplinks in data centers and enterprise network environments, providing an optical short-reach solution for 25G Ethernet and related high‑speed applications.

Advantages

The transceiver supports a 25 Gbit/s data rate and uses an industry-standard SFP28 interface to ensure compatibility with a wide range of network equipment. Its LC duplex connector and multimode optic design enable straightforward installation in existing fiber infrastructures. The hot-pluggable module minimizes downtime during upgrades or replacements and is intended for reliable short-reach optical connections in dense network deployments.

Suitable for

• 25G Ethernet uplinks between switches and servers
• High-speed switch-to-switch interconnects in data centers
• Server network interface expansion in enterprise racks
• Short-reach multimode fiber links up to 300 m

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 m on multimode fiber
• Form factor: SFP28, hot-pluggable
• Application: 25G Ethernet and compatible optical protocols

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, router or server NIC while the host is powered on or following the vendor’s hot‑swap procedure. Connect an appropriate LC duplex fiber patch cable to the transceiver ports, ensuring correct transmit/receive orientation. Verify link status and speed through the host equipment management interface and, if necessary, configure the port for 25G operation according to the switch or NIC documentation.

Recommendations

Use multimode fiber (OM3/OM4 recommended) and quality LC patch cords for best performance at the specified 300 m range. Confirm compatibility with the network device vendor and test links after installation to ensure expected throughput and signal integrity.
