SFP28 Transceiver Module CBO JL293A-BO 25 Gbit/s 850 nm

The SFP28 Transceiver Module CBO JL293A-BO 25 Gbit/s 850 nm is a short-range multimode fiber optical transceiver designed to deliver 25 Gigabit Ethernet connectivity for compatible switches and servers. It supports 25 Gbit/s data rates over 850 nm wavelength, providing a compact pluggable solution for high-density network environments such as data center uplinks and server interconnects. The module is intended for use with multimode fiber cabling and is suitable for installations requiring low-latency, high-bandwidth fiber links.

Advantages

This SFP28 transceiver offers a standardized small-form-factor package that saves rack space and simplifies upgrades from 10G to 25G infrastructure. It provides consistent 25 Gbit/s throughput with an 850 nm laser optimized for short-range multimode links, enabling predictable performance in dense networking environments. Compatibility with common SFP28 ports makes the module a versatile choice for upgrading existing switch and server interfaces without major infrastructure changes.

Suitable for

• Data center uplinks and switch-to-switch connections
• Server to top-of-rack or leaf switch interconnects
• High-performance computing clusters with multimode fiber
• Short-distance fiber backbones within enterprise or campus networks

Key specifications

• Form factor: SFP28 small form-factor pluggable
• Data rate: 25 Gbit/s
• Wavelength: 850 nm (VCSEL for multimode fiber)
• Optical fiber type: Multimode fiber (MMF)
• Typical reach: short-range multimode links (designed for intra-rack and short inter-rack connections)
• Interface: Duplex LC connector
• Hot-pluggable design for inline upgrades and maintenance

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch or server until it clicks into place; ensure the host device is powered down if the manufacturer recommends doing so. Connect multimode fiber with an LC duplex connector between the transceiver and the corresponding port on the remote device, observing proper fiber handling and bend radius limits. Configure the host interface settings as required by the network operating system to enable 25 Gbit/s operation and verify link status and diagnostics through the device management interface.

Recommendations

Use OM3 or OM4 multimode fiber for optimal reach and performance, maintain clean LC connectors to avoid signal loss, and follow link budget and environmental specifications of your networking equipment. Confirm compatibility with the switch or server vendor and validate link operation after installation to ensure reliable 25G connectivity.
