Description
Description
The Ubiquiti 100G PSM4 Single-Mode Optical Module (UACC-OM-QSFP28-PSM4) is a high-performance QSFP28 transceiver designed to deliver ultra-fast 100 Gbps connectivity over distances up to 2 km using single-mode fibre. Ideal for enterprise networks, data centres, and aggregation layer deployments, this optical module provides reliable, high-bandwidth connectivity for demanding network infrastructures.
Featuring an MPO-12 Type B APC connector and operating at a 1310 nm wavelength, the UACC-OM-QSFP28-PSM4 is compatible with both QSFP28 and QSFP+ interfaces, offering flexibility for modern UniFi networking equipment. This module requires OS2 single-mode fibre for full 2 km range; transmission distance is limited to 500 m with OS1 single-mode fibre.
Key Features
- 100 Gbps maximum data rate for ultra-high-speed connections
- QSFP28 form factor with MPO-12 Type B APC connector
- Supports single-mode fibre connections up to 2 km (with OS2 fibre)
- Compatible with QSFP28 and QSFP+ interfaces
- 1310 nm TX/RX wavelength
