Ubiquiti UACC-OM-QSFP28-SR4 - 100 Gigabit QSFP28 SR4 multi-mode optical transceiver module, beige, grey

The Ubiquiti UACC-OM-QSFP28-SR4 is a 100G QSFP28 SR4 multi-mode optical transceiver (MPO-12 UPC) designed for high-density data centre environments. It converts electrical data into optical signals for transmission over fibre infrastructure. Supporting 100 Gbps data rates, it facilitates low-latency communication between core switches and high-performance routers. This transceiver is intended for short-reach, high-bandwidth applications over multi-mode fibre, suitable for high-throughput server clusters, large-scale storage area networks, and core network backbones.

The transceiver is compatible with networking equipment featuring QSFP28 and QSFP+ slots and uses an MPO-12 UPC Type B connector. With a power consumption of 2.5 W, the module is suited for high-density environments where thermal management is a priority. It is designed for short-distance interconnects that require stable, high-bandwidth throughput. This ensures compatibility with the requirements of 100G fibre systems. The beige and grey finish follows industry standards for identifying multi-mode fibre components.

• 100GBase-SR4 networking standard — Ensures interoperability with hardware using the same four-lane optical protocols.
• Fibre optic connectivity — Provides data integrity through electrical isolation and resistance to electromagnetic interference.
• QSFP28 form factor — Standardised physical format ensures a secure fit in high-density network ports.
• Multi-mode fibre (MMF) support — Designed for high-speed, short-distance optical links.
• 100-metre maximum range — Supports connectivity across data centre rows and within-rack cabling.
• UPC Type B interface — Specifies the polishing and pin configuration required for secure MPO-12 connector mating.
