CBO SFP28-25G-ESR-IT-BO SFP28 25 Gbit/s multimode-LC-transceiver, 300 m

SFP28 CBO SFP28-25G-ESR-IT-BO is a 25 Gbit/s multimode optical transceiver with an LC duplex connector designed for short-range fiber links up to 300 m. The module fits SFP28 slots in compatible switches and servers and supports high-speed data transmission in data centers and enterprise LAN environments. It provides hot-pluggable operation for straightforward replacement or installation and is intended for multimode OM3/OM4 fiber installations where 25 Gbit/s connectivity is required.

Advantages

The transceiver delivers a 25 Gbit/s physical interface with low power consumption and supports reliable short-reach links up to 300 meters on multimode fiber. Its LC duplex connector and standardized SFP28 form factor ensure compatibility with a wide range of network equipment. Hot-pluggable design enables tool-free insertion and removal, reducing maintenance time. The module is suitable for single-lane 25 Gigabit Ethernet applications and is designed to meet common interoperability expectations for multimode short-reach optics.

Suitable for

• 25 Gigabit Ethernet links in data centers
• Top-of-rack and aggregation switches
• Server network interfaces requiring 25 Gbit/s
• Short-range multimode fiber runs (up to 300 m)

Key specifications

• Form factor: SFP28 (hot-pluggable)
• Data rate: 25 Gbit/s
• Fiber type: Multimode (OM3/OM4 compatible)
• Connector: LC duplex
• Maximum reach: 300 meters on multimode fiber
• Single-lane operation for 25G Ethernet

How to use

Insert the transceiver into an available SFP28 slot on a compatible switch or server while the host power is on; the hot-pluggable design supports live installation. Connect LC duplex multimode fiber patch cables ensuring correct polarity and secure connections. Configure the host interface as required by the switch or server operating system or management interface, verify link status and speed, and monitor diagnostics if supported by the equipment. For removal, power down the port if recommended by the equipment vendor, then pull the module straight out to avoid damage to the connector.

Recommendations

Use multimode fiber cabling of appropriate grade (OM3 or OM4) and LC duplex patch cords with correct polarity. Verify compatibility with the host equipment's supported transceiver list and firmware requirements before deployment. For reliable performance, avoid sharp bends in fiber, maintain clean connector endfaces, and follow ESD precautions when handling the module.
