BlueOptics QSFP56 200GBASE-SR4 Transceiver R5Z83A-BO, MPO/MTP, Multimode 850nm, 100m, DDM, 0–70°C

BlueOptics QSFP56 200GBASE-SR4 Transceiver R5Z83A-BO is a compatibility-listed optical module designed for short-reach 200 Gigabit Ethernet links over multimode fiber. Using an MPO/MTP interface and operating at a wavelength of 850 nm, this QSFP56 transceiver supports up to 100 m reach on appropriate OM3/OM4 cabling and provides digital diagnostic monitoring (DDM) for real-time status information. The module is specified for standard data center ambient temperatures from 0°C to +70°C and fits QSFP56 ports used in high-density aggregation and switch-to-switch connections.

Advantages

The BlueOptics QSFP56 transceiver delivers 200GBASE-SR4 performance in a compact QSFP56 form factor with an MPO/MTP multimode fiber interface, enabling high-density cabling and simplified parallel fiber connections. Integrated DDM offers monitoring of optical parameters such as temperature and received/transmitted power, which helps with diagnostics and link verification. Its compatibility listing for common QSFP56 hosts makes it suitable for multi-vendor environments where confirmed interoperability is required.

Suitable for

• Short-reach 200G data center links over multimode fiber (OM3/OM4)
• High-density switch-to-switch aggregation using QSFP56 ports
• Parallel MPO/MTP cabling deployments and breakout configurations
• Environments requiring DDM for optical diagnostics and monitoring

When it may not be suitable

This transceiver is intended for short-reach multimode applications and is not suitable for single-mode long-haul links or distances beyond the specified 100 m on OM3/OM4. It requires QSFP56 or compatible host ports and MPO/MTP cabling; it will not fit SFP-based interfaces or non-MPO connector systems.

Key specifications

• Data rate: 200 Gbps (200GBASE-SR4)
• Fiber type: Multimode fiber (OM3/OM4)
• Wavelength: 850 nm
• Maximum reach: up to 100 m (OM3/OM4 dependent)
• Connector: MPO/MTP
• Monitoring: Digital Diagnostic Monitoring (DDM)
• Operating temperature: 0°C to +70°C

How to use

Install the BlueOptics QSFP56 transceiver into a compatible QSFP56 port following your host equipment's hot-plug and electrostatic discharge (ESD) guidelines. Connect MPO/MTP multimode fiber jumper or trunk cables ensuring correct polarity and fiber mapping for SR4 parallel operation. Verify link status and monitor optical parameters via the host platform's interface or management tools that read the module's DDM data. For breakout use, combine with appropriate MPO-to-LC or MPO breakout cables and configure the connected devices accordingly.

What to consider before purchase

• Confirm host equipment supports QSFP56 form factor and 200GBASE-SR4 operation
• Ensure cabling is OM3 or OM4 multimode fiber and that length does not exceed 100 m for required link margin
• Verify MPO/MTP connector compatibility and correct fiber polarity for parallel links
• Check whether the host requires compatibility-listed or vendor-locked transceivers

Usage recommendations

Use this transceiver in short-reach, high-density data center topologies with certified OM3/OM4 multimode fiber and MPO/MTP cabling. Monitor DDM readings during commissioning to confirm optical budgets and periodically check diagnostic values to detect potential fiber or connector degradation.
