Ubiquiti UACC-OM-QSFP28-PSM4 QSFP28 Transceiver

Overview

The Ubiquiti UACC-OM-QSFP28-PSM4 is a QSFP28 transceiver module designed for 100Gbps Ethernet connections over single-mode fiber. It enables high-bandwidth data transmission up to 2 kilometers, making it suitable for backbone connections in data centers or between network aggregation points. This module utilizes a standard QSFP form factor for broad compatibility with network switches and routers.

Compatibility

This transceiver is designed for use with Ubiquiti network hardware and other devices supporting the QSFP28 form factor and 100GBASE-SR4 standards. It is intended for integration into Ubiquiti's switching platforms that feature QSFP28 ports, facilitating high-speed network uplinks and inter-switch links.

Installation Notes

The UACC-OM-QSFP28-PSM4 operates within an ambient temperature range of 0 to 70° C (32 to 158° F). It is a Class 1 Laser Product; avoid direct eye exposure to the optical ports or fiber ends while the device is powered. The module requires an MPO-12 Type B UPC connector for fiber termination.
