QSFP Transceiver Module BlueOptics QSFP-100G-SR4-BO Fiber Optic QSFP28

The BlueOptics QSFP-100G-SR4-BO is a QSFP28 fiber optic transceiver module engineered for short-reach 100GBASE-SR4 links over multimode fiber. Housed in an aluminium casing and weighing approximately 40 g, it uses an MTP/MPO connector and supports simultaneous transmit and receive lanes with 850 nm optics. The module follows MSA-compliant QSFP28 form-factor standards and is suitable for deployment in data center switches, routers and other high-performance networking equipment that support 100GBASE-SR4 optics.

Advantages

The transceiver provides 100 Gbit/s optical data transmission over multimode fiber with MPO/MTP connectivity and integrated digital diagnostics for live monitoring of supply voltage, laser bias current, transmitted and received optical power, and internal temperature. Built to MSA specifications, the module is compatible with systems that accept standard QSFP-100G-SR4 optics and is constructed from high-quality components to offer reliable operation and extended service life.

Suitable for

• 100G short-range interconnects in data centers (up to multimode fiber reach)
• High-performance switch-to-switch and switch-to-server links
• Fibre Channel over Ethernet and high-speed Ethernet aggregation
• Environments requiring MPO/MTP trunking and parallel optics

How to use

Install the BlueOptics QSFP-100G-SR4-BO into a compatible QSFP28 port following the host device manufacturer’s hot-plug and ESD handling procedures. Connect an appropriate MPO/MTP multimode fiber patch cord or trunk cable, ensuring correct polarity and fiber mapping for SR4 parallel optics. Confirm link status and diagnostics through the host device management interface or supported DDM/DOM readout to verify optical power levels and module temperature. When removing the module, follow the device shutdown or safe removal instructions to avoid data interruptions and refrain from touching the optical interfaces.

Recommendations

Use multimode OM3/OM4 fiber for best range and performance with 100GBASE-SR4 links, keep MPO/MTP connectors clean and capped when not in use, and verify that the target hardware supports QSFP-100G-SR4 optics and DDM/DOM if you need diagnostic monitoring.
