SFP28 Fiber Optic Transceiver CBO 0CTW7 25Gbps 850nm

The BlueOptics SFP28 Fiber Optic Transceiver CBO 0CTW7 25Gbps 850nm is a compact hot-swappable module for high-speed multimode optical links. Supporting a 25 Gbps data rate over OM3/OM4 multimode fiber at an 850 nm wavelength, this SFP28 transceiver is intended for use in compatible SFP28 ports on switches, network interface cards and servers. The module provides standard optical connectivity in a small form factor to enable short-reach uplinks and server-to-switch connections in data centers and enterprise networks.

Advantages

The transceiver delivers 25 Gbps throughput with low latency and supports standard LC duplex fiber connections. Its hot-pluggable SFP28 form factor simplifies installation and replacement without disrupting operations. Optimised for multimode fiber, the module offers reliable short-reach performance for aggregation and top-of-rack links while maintaining compatibility with common networking equipment that accepts SFP28 optical modules.

Suitable for

• Short-reach 25 Gbps uplinks between switches and aggregation devices
• Server-to-switch connections in data centers and enterprise racks
• High-density access and top-of-rack network deployments
• Multimode fiber backbones using OM3/OM4 cabling

Key specifications

• Data rate: 25 Gbps
• Wavelength: 850 nm
• Optical interface: LC duplex
• Fiber type: Multimode (OM3/OM4)
• Form factor: SFP28, hot-swappable
• Typical reach: Short-reach multimode links (designed for data centre interconnects)

How to use

Insert the SFP28 transceiver into a compatible SFP28 port until it latches; ensure the host device is powered and supports 25 Gbps modules. Connect LC duplex multimode fiber patch cables (OM3/OM4) following correct polarity and secure connections at both ends. Monitor link status via the host device management interface and replace the module by unlocking and removing it while the system remains powered if a hot-swap is required. Follow equipment vendor guidelines for driver and firmware compatibility where applicable.

Recommendations

Use this 850 nm SFP28 transceiver for short-reach multimode links in data centre and enterprise rack environments. Match fiber type (OM3/OM4), maintain clean LC connectors to minimise loss, and confirm that the target port supports SFP28 optical modules and 25 Gbps operation for optimal performance.
