Transceptor SFP28 CBO Nokia BO27Q856S1D módulo 25G SR para fibra multimodo de corta distancia

SFP28 Transceiver CBO Nokia BO27Q856S1D 25G SR module for short-range multimode fiber is a small form-factor pluggable optical transceiver designed to support 25 Gigabit Ethernet links over multimode fiber. The module provides a hot-swappable interface compatible with SFP28 ports on network switches and servers, enabling compact, high-density deployment in data centers and network aggregation points. It is intended for short-range connections where 25G bandwidth and the SFP28 form factor are required.

Advantages

The module supports 25G Ethernet throughput in a compact SFP28 package, allowing high port density and simplified upgrades from 10G to 25G infrastructures. Hot-swappable compatibility reduces maintenance time and allows replacement without powering down host devices. Designed for short-range multimode fiber, the transceiver minimizes footprint while delivering a standardized optical interface for interoperable deployment in racks, top-of-rack switches and short-reach uplinks.

Suitable for

• Data center rack interconnects
• Top-of-rack (ToR) switches
• Short-reach uplinks between aggregation and access equipment
• Server network interfaces requiring 25G bandwidth

Key specifications

• Form factor: SFP28 small form-factor pluggable
• Data rate: 25 Gigabit Ethernet
• Optical range: short-range operation over multimode fiber
• Interface: hot-swappable optical transceiver for SFP28 ports
• Application: multimode fiber short-reach links in data center and access networks

How to use

Install the SFP28 module into an available SFP28 port on a compatible network switch or server while the host device is powered according to the vendor's hot-swap guidelines. Connect appropriate multimode duplex fiber patch cords into the transceiver's optical connector and ensure the receiving end uses a compatible 25G SR transceiver. Verify link status on the host device and configure network settings for 25G operation as required by your equipment. Follow standard electrostatic discharge (ESD) precautions during handling and avoid touching optical interfaces to prevent contamination.

Recommendations

Use multimode fiber with suitable connectors and maintain clean fiber endfaces to ensure reliable 25G SR links. Confirm compatibility with the switch or server vendor's supported transceiver list if strict interoperability policies are in place. Store unused modules in protective packaging to prevent dust and damage.
