Ricetrasmettitore SFP28 CBO SFP28-25G-ESR-NK-BO 25 Gbit/s LC multimodale 300 m

The CBO SFP28-25G-ESR-NK-BO is an SFP28 optical transceiver module that supports a 25 Gbit/s data rate over multimode fiber with an LC duplex connector and a maximum reach of up to 300 m. Designed for short-reach 25 Gigabit Ethernet links in data center and enterprise network environments, this hot-pluggable module provides a compact form factor for direct insertion into SFP28 ports on switches, servers and storage devices. The module implements standard electrical and optical interfaces to work with compatible network equipment and simplify upgrades to 25GbE connectivity.

Advantages

The transceiver offers a compact SFP28 form factor with 25 Gbit/s throughput and multimode fiber support for reliable short-range connections. Its LC duplex connector and standardized interface enable straightforward hot-pluggable installation and replacement without system downtime. The 300 m reach over multimode fiber covers common intra-rack and inter-rack connections in data centers, while the module’s design focuses on interoperability with SFP28 ports to support rollouts of 25GbE links.

Suitable for

• Short-range 25 Gigabit Ethernet links within data centers and server rooms
• Connections between switches, top-of-rack devices and storage arrays
• Upgrading access or aggregation ports to 25GbE in enterprise networks
• Multimode fiber spans up to 300 m for intra-building links

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: Multimode fiber (MMF)
• Maximum reach: up to 300 m over multimode fiber
• Connector type: LC duplex
• Form factor: SFP28 hot-pluggable module
• Application: Short-reach 25 Gigabit Ethernet links

How to use

Power down is not required for installation; insert the SFP28 module into a compatible SFP28 port until it seats firmly and engage any retaining mechanism on the host device. Connect the LC duplex multimode fiber patch cable, ensuring correct polarity, and verify that the link LEDs and host interface report a valid 25GbE connection. For removal, unlatch the module’s retention and gently pull it from the port. Follow the host equipment’s instructions for port configuration and transceiver management to enable the intended link parameters.

Recommendations

Use OM3/OM4 multimode fiber for reliable performance at the specified distances, maintain clean fiber connectors to prevent signal loss, and verify compatibility with the host device’s SFP28 ports and firmware. For optimal results in data center deployments, pair the transceiver with appropriate patching and cable management to minimize bend loss and ensure consistent 25GbE performance.
