BlueOptics QSFP56 transceiver compatible with Infortrend 9370CSFP200G-0010 — 200GBASE‑SR4, 850 nm, up to 100 m

BlueOptics QSFP56 transceiver compatible with Infortrend 9370CSFP200G-0010 is a Small Form-Factor Pluggable module designed for 200GBASE‑SR4 multimode links. It operates at a wavelength of 850 nm and aggregates four 50 G lanes inside a single QSFP56 housing, offering a multimode reach up to 100 m over OM3/OM4 cabling. The module is intended for high‑speed data centre and switch‑to‑switch connections where compact, hot‑pluggable optics and high port density are required.

Advantages

The transceiver provides compact 200 G capacity in a single QSFP56 form factor, enabling denser switch and chassis deployments without increasing rack space. Its multimode SR4 design supports parallel multi‑lane transmission, reducing cabling complexity for short‑reach aggregation and leaf‑spine fabrics. Being hot‑pluggable, the module can be installed or replaced without powering down the host device, and the standardized optical parameters ensure predictable performance when used with compatible multimode fibre.

Suitable for

• Data centre aggregation and spine‑leaf switch links
• High‑density switch ports requiring 200G capacity
• Short‑reach multimode fibre connections (OM3/OM4) up to 100 m
• Environments where hot‑swappable optics simplify maintenance

When it may not be suitable

This QSFP56 module is designed specifically for multimode SR4 links at 850 nm and is not intended for single‑mode long‑reach applications or direct attach copper. It will not support distances beyond the specified 100 m over OM3/OM4 fibre and is not suitable for networks that require single‑lane or lower speed interfaces without appropriate breakout or conversion hardware.

Key specifications

• Form factor: QSFP56 (Small Form‑Factor Pluggable)
• Data rate: 200 G (4×50 G lanes)
• Class/type: 200GBASE‑SR4 multimode optical transceiver
• Wavelength: 850 nm
• Maximum reach: up to 100 m on OM3/OM4 multimode fibre
• Connector type: MPO/MTP multimode fibre interface
• Hot‑pluggable: yes

How to use

Insert the QSFP56 transceiver into a compatible QSFP56 port on the switch or host device while the device is powered on, taking care to align the module with the cage and to avoid touching the fibre interface. Use MPO/MTP multimode patch cords rated for OM3 or OM4 to connect to parallel multimode cabling or to MPO‑terminated patch panels. Verify link status and module diagnostics through the host device interface; consult the device documentation for any required configuration or lane breakout settings if converting to multiple 50 G links. Clean optical connectors before mating and follow standard electrostatic discharge precautions during handling.

What to consider before purchase

• Confirm host device compatibility with QSFP56 form factor and 200GBASE‑SR4 optics
• Ensure fibre infrastructure uses OM3 or OM4 multimode cabling for the specified reach
• Check whether MPO/MTP connectors match your patching and panel equipment
• Determine whether you need breakout cables or adapters to convert to multiple 50 G interfaces

Usage recommendations

Use this BlueOptics QSFP56 module for short‑reach, high‑density links in data centre fabrics and verify compatibility with the switch vendor’s supported optics list. Regularly inspect and clean MPO/MTP connectors, and monitor transceiver diagnostics through the host to ensure stable 200G links.
