SFP28 transceiver module BlueOptics SFP28-25G-ESR-ZY 25000 Mbit/s 850 nm

The BlueOptics SFP28-25G-ESR-ZY is a compact fiber optic transceiver module for SFP28 interfaces, engineered for 25 Gbit/s data links. Operating at an 850 nm wavelength, this module supports short-range multimode connections commonly used in data center and enterprise networking environments. Its lightweight silver housing and SFP28 form factor make it suitable for use in high-density switch and server ports where reliable, high-bandwidth connectivity is required.

Advantages

The module provides a standardized SFP28 interface enabling straightforward integration into compatible switches, routers and network interface cards without additional configuration. With a 25,000 Mbit/s maximum data transfer rate and 850 nm optical wavelength, it delivers the throughput needed for server-to-switch and switch-to-switch links over multimode fiber. The small, industry-standard form factor and low weight reduce space and load on port modules while maintaining electrical and optical compatibility.

Suitable for

• Short-reach multimode fiber links in data centers
• 25 Gbps uplinks between servers and top-of-rack switches
• High-density network environments requiring SFP28 ports

How to use

Install the BlueOptics SFP28-25G-ESR-ZY into an available SFP28 port on a compatible switch, router or network interface card while the host device is powered down or following hot-swap guidelines of the equipment vendor. Connect the appropriate multimode fiber patch cable to the transceiver’s optical interface, ensuring correct polarity and connector type. After physical installation, verify link status and negotiated speed in the host device management interface and confirm optical parameters if supported.

Recommendations

Use standard OM3/OM4 multimode fiber for optimal short-reach performance at 850 nm and keep fiber connectors clean to maintain signal quality. Verify compatibility with the specific switch or server vendor and consult equipment documentation for supported SFP28 modules and hot-swap procedures.
