SFP28 Transceiver BlueOptics BO27Q856S1D 25GBASE-SR multimode 100 m — compatible with Infortrend

BlueOptics BO27Q856S1D is an SFP28 optical transceiver that supports the 25GBASE-SR standard for multimode fiber links up to 100 meters. This hot-pluggable module delivers a 25 Gbps data rate and is intended for short-range uplink connections, switch-to-switch links and other intra-rack or adjacent-rack network paths. The module is listed as compatible with Infortrend systems and is designed for use in data center, SAN and high-speed Ethernet environments where compact, low-latency optical connectivity is required.

Advantages

The transceiver offers a standardized SFP28 form factor for easy insertion into compatible ports and supports 25 Gbps line rate for high-bandwidth short-reach applications. Its design for multimode fiber enables cost-effective connections within racks and across short distances without the need for single-mode optics. Hot-pluggability allows replacement or upgrade without shutting down the host device, minimizing service disruption.

Suitable for

• Short-reach 25 Gbps uplink and switch-to-switch connections over multimode fiber
• Data center top-of-rack and end-of-row connectivity within 100 m
• Storage area networks (SAN) and server interconnects requiring 25G links
• Network equipment that lists compatibility with Infortrend devices

When it may not be suitable

This module is intended for multimode short-range links and is not suitable for long-distance or single-mode fiber applications. It does not provide built-in features for copper connections or legacy electrical interfaces; for 10G, 40G or slower links you should select a module that matches those specific speeds and standards.

Key specifications

• Form factor: SFP28 (hot-pluggable)
• Data rate: 25 Gbps
• Standard: 25GBASE-SR
• Fiber type: Multimode fiber
• Maximum reach: up to 100 m (depending on fiber type and connector quality)
• Wavelength: short-range multimode optical wavelength (per 25GBASE-SR specification)

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, server or storage device while the host is powered on or follow your device vendor recommendations for hot-plug operations. Connect multimode fiber patch cords (with appropriate connectors) between transceivers on each end, ensuring fiber polarity and connector types match. Verify link status and speed through the host device management interface and monitor optical parameters if supported. Replace or remove the module following ESD-safe procedures.

What to consider before purchase

• Confirm physical port compatibility on your switch, server or storage device (SFP28 ports and supported 25G speeds)
• Verify that the device firmware or vendor compatibility list includes third-party transceivers or specifically lists compatibility with Infortrend systems
• Ensure your multimode fiber type (OM3/OM4) and connector type support 25GBASE-SR at the desired distance
• Check required optical budget and transceiver power/wavelength specifications against your infrastructure

Usage recommendations

Use high-quality OM3 or OM4 multimode fiber and matched connectors for reliable 25G performance up to 100 m, keep fiber runs within recommended distances, and maintain clean connectors to avoid signal loss. Follow host vendor guidelines for third-party transceiver use and monitor link health after installation.
