CBO Transceiver SFP28-25G-SR Fiber Optic 25G 850nm Multimode Short Range

CBO Transceiver SFP28-25G-SR Fiber Optic 25G 850nm Multimode Short Range is a 25 Gigabit SFP28 transceiver module designed for short-range multimode fiber links. It operates at an 850 nm wavelength and supports 25G data rates in a compact, hot-pluggable SFP28 form factor compatible with SFP28 ports. The module is intended for high-speed connections in data centers, server-to-switch links and aggregation points where low latency and reliable short-range transmission are required.

Advantages

The transceiver provides a standardized SFP28 interface for straightforward hot-swap installation and broad compatibility with equipment that supports SFP28 modules. Operating at 25G over multimode fiber with an 850 nm VCSEL source, it offers low-latency signal transmission suitable for dense networking environments. Its compact form factor reduces space requirements in rack-mounted equipment and simplifies upgrades of existing 10G infrastructure to 25G where multimode cabling is available.

Suitable for

• Short-range connections within data centers
• Server-to-switch uplinks and top-of-rack aggregation
• High-density switch ports requiring 25G speeds
• Multimode fiber environments using 850 nm optics

Key specifications

• Nominal data rate: 25 Gigabit Ethernet
• Wavelength: 850 nm
• Fiber type: Multimode
• Form factor: SFP28, hot-pluggable
• Typical application: Short-range links within racks and between adjacent racks
• Connector type: Duplex LC compatible with multimode patch cords

How to use

Insert the SFP28 module into a compatible SFP28 port on a switch, server NIC or transceiver cage while the host device is powered on or during maintenance windows, following the host equipment manufacturer’s guidance for hot-plugging. Connect duplex multimode LC patch cords to the module and to the remote transceiver or patch panel. Verify link status through the host device management interface and ensure matching speed and duplex settings where applicable. Use appropriate fiber cleaning procedures before connection to maintain signal integrity.

Recommendations

For reliable operation, use multimode fiber rated for the intended short-range distances and ensure patch cords and adapters are clean and in good condition. Confirm compatibility with the host equipment's SFP28 port and keep firm ventilation around equipment to avoid overheating in dense enclosures.
