100G QSFP28 SR4 glasvezel-transceiver BlueOptics 100G-QSFP28-SR4-BO

The BlueOptics 100G-QSFP28-SR4-BO is a 100GBASE-SR4 fiber optic transceiver module with a QSFP28 interface and an MTP/MPO connector. Designed for multi-mode fiber links, it supports 100 Gbit/s Ethernet transmission over short-reach multimode cabling. The module is housed in a lightweight aluminium enclosure and weighs approximately 0.04 kg, making it suitable for high-density installations where space and port density matter.

Advantages

The transceiver follows MSA-compatible QSFP28 form-factor specifications and provides interoperable optical connectivity for devices that accept 100GBASE-SR4 QSFP28 modules. Its MTP/MPO connector enables parallel optical links for simultaneous transmit and receive channels. The aluminium casing offers a compact, thermally conductive shell that contributes to mechanical stability and heat dissipation. The product is compatible with common short-range multimode fiber applications and supports digital diagnostic monitoring when the host hardware supports the feature.

Suitable for

• 100G Ethernet links over multimode fiber in data center aggregation and spine networks
• High-density switch and router uplinks requiring QSFP28 ports
• Short-reach interconnects between switches, routers, and storage systems within a single building or campus

Key specifications

• Interface type: QSFP28
• Connector type: MTP/MPO (parallel multimode fiber)
• Supported protocol: 100GBASE-SR4 (100 Gbit/s over multimode fiber)
• Typical reach: short-range multimode fiber (designed for up to 100 m depending on fiber type and link conditions)
• Housing material and colour: aluminium (aluminium colour)
• Weight: ~0.04 kg
• Form factor: QSFP28 pluggable transceiver

How to use

Install the module into a compatible QSFP28 port on a switch, router or other network device while the device is powered down or following the vendor’s hot-swap guidelines. Connect an appropriate MPO/MTP multimode fiber patch cord between the transceiver and the corresponding patch panel or transceiver at the remote end, ensuring correct polarity and fiber type (multimode). Verify link negotiation and speed settings on the host device and enable Digital Diagnostic Monitoring (DDM/DOM) if supported by the hardware to monitor voltage, temperature and optical parameters. Follow standard electrostatic discharge (ESD) precautions during handling and keep the connector dust caps on until connection.

Recommendations

For optimal performance, use OM3 or OM4 multimode fiber and industry-standard MPO/MTP patch cords, maintain clean connectors, and verify that the network hardware firmware supports 100GBASE-SR4 QSFP28 modules. Confirm compatibility with the host device vendor documentation prior to deployment.
