QSFP56 Network Transceiver Module BlueOptics QSFP56-200G-SR4-BC4-BC-BO Fiber optic MTP/MPO

The BlueOptics QSFP56-200G-SR4-BC4-BC-BO is a 200G fiber optic transceiver module with a QSFP56 interface and an MTP/MPO connector designed for high-density data center and enterprise network applications. It supports multimode fiber links and implements SR4 optics for short-reach 200GBASE-SR4 connections. The module has an aluminium housing and weighs approximately 0.04 kg, providing a compact, lightweight option for upgrades or new installations where space and thermal performance are considerations.

Advantages

The transceiver is compatible with QSFP56 ports and follows MSA interface conventions, enabling interoperability with hardware that supports 200GBASE-SR4 optics. It uses an MPO/MTP connector for parallel multimode fiber transmission and includes digital diagnostics monitoring functionality for remote measurement of supply voltage, temperature, transmit and receive power and laser bias current when supported by host equipment. The aluminium enclosure offers a lightweight, durable package for rack-mounted systems.

How to use

Install the QSFP56 module into a compatible QSFP56 port on a switch, router or storage system following the host vendor’s insertion and removal procedures. Connect MPO/MTP multimode fiber patch cords to the module’s connector and ensure correct polarity and aligned fiber mapping for SR4 parallel lanes. Verify that the host device recognizes the transceiver and, if available, enable or monitor the digital diagnostics interface to read real-time parameters such as optical power and temperature. Follow standard electrostatic discharge (ESD) precautions during handling and avoid bending the fiber beyond recommended limits.

Recommendations

To achieve optimal performance, pair the transceiver with appropriate OM3/OM4 multimode fiber and high-quality MPO/MTP patch cords, ensure clean connectors, and confirm host compatibility with 200GBASE-SR4 QSFP56 modules and DDM/DOM support. Regular inspection and cleaning of fiber endfaces and correct cable management will help maintain signal quality and long-term reliability.
