SFP28-transceiver CBO SFP28-25G-ESR-RW-BO 25 Gbit/s LC 300 m

The BlueOptics SFP28-25G-ESR-RW-BO is an SFP28 optical transceiver that supports a 25 Gbit/s data rate with an LC duplex connector and a reach of up to 300 meters over multimode fiber. Designed for use in data centers and enterprise networks, this module provides a compact, hot-pluggable form factor suited for switch and server uplinks. The transceiver implements industry-standard interfaces for compatibility with equipment that accepts SFP28 modules and is intended for short-reach 25GbE links where reliable high-speed connectivity is required.

Advantages

This SFP28 transceiver delivers 25 Gbit/s bandwidth in a small SFP28 form factor, enabling high-density port configurations. The LC duplex interface ensures standardized fiber connections while the multimode reach of up to 300 m supports typical intra-data-center and campus cabling scenarios. The module is hot-pluggable for minimal service interruption during installation or replacement and is optimized for low-latency transmission in aggregation and uplink applications.

Suitable for

• Server uplinks in data center racks
• Switch-to-switch aggregation links
• Top-of-rack (ToR) and leaf-spine architectures
• Short-reach multimode fiber connections up to 300 m

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Fiber type: Multimode fiber (MMF)
• Maximum reach: 300 meters (over MMF)
• Form factor: SFP28
• Hot-pluggable: Yes

How to use

Install the transceiver by inserting it into a compatible SFP28 slot on a switch, router or server port while the host device is powered on or according to the equipment vendor’s guidelines for hot-plug operations. Connect LC duplex multimode fiber patch cords to the module ensuring correct transmit/receive orientation. Verify link status via the host device’s management interface and configure the network interface for 25GbE operation if required. Replace modules by gently pulling the release tab and removing the transceiver, taking care to protect fiber ends with dust caps when unplugged.

Recommendations

Use multimode fiber patched and cleaned to industry standards, keep transmitter and receiver dust caps on until connection, and confirm compatibility with the host device’s SFP28 ports. For reliable operation maintain fiber routing to avoid tight bends and follow the data center cabling plan to ensure link reaches do not exceed 300 m on multimode fiber.
