BlueOptics PAN-T-Q28-100GBASE-SR4-BO network transceiver module QSFP28 MTP/MPO

The BlueOptics PAN-T-Q28-100GBASE-SR4-BO is a QSFP28 fiber optic transceiver module designed for high-speed short-reach multimode links. It implements the 100GBASE-SR4 specification with an MTP/MPO connector, supporting parallel transmission over multimode fiber and a compact QSFP28 form factor. The module is lightweight (approx. 40 g) and finished in aluminium colour, making it suitable for dense installations in data centers and enterprise network environments that require reliable 100 Gbps connectivity.

Advantages

This QSFP28 transceiver delivers 100 Gbps multimode performance compliant with SR4 optics using 850 nm VCSEL-based Tx/Rx channels and an MTP/MPO interface for four-lane parallel fiber connections. The module follows MSA mechanical and electrical standards for QSFP28, enabling interoperability with compatible switches, routers and other network equipment. Its compact design and low weight reduce space and thermal impact in high-density racks. The module also supports digital diagnostic monitoring (DDM/DOM) functionality for remote monitoring of operating parameters when the host hardware exposes that interface.

Suitable for

• High-density data center uplinks and switch-to-switch aggregation at 100 Gbps
• Short-reach multimode fiber connections (parallel MPO/MTP cabling)
• Enterprise backbone links and high-performance computing clusters
• Environments requiring interoperable QSFP28 MSA-compliant transceivers

How to use

Install the QSFP28 module into a compatible QSFP28 port on a switch, router or other network device while the equipment is powered down or per the vendor’s hot-plug guidelines. Connect an appropriate MTP/MPO multimode fiber patch cord between this transceiver and the paired transceiver or patch panel, ensuring correct polarity for the four parallel lanes. Verify link negotiation and monitor operational status through the host device management interface. If supported by the host, use the DDM/DOM readings to check supply voltage, temperature and optical power metrics for diagnostics.

Usage recommendations

Use multimode fiber types and cabling (OM3/OM4) suitable for 100GBASE-SR4 distances, verify MPO/MTP connector cleanliness before connection, and confirm hardware compatibility with QSFP28 100GBASE-SR4 modules to ensure reliable operation and expected reach.
