Ubiquiti UACC-OM-QSFP28-PSM4 – 100G PSM4 QSFP28 Single-Mode Optical Module
Overview
The Ubiquiti UACC-OM-QSFP28-PSM4 is a 100G PSM4 single-mode optical transceiver in a QSFP28 form factor. It is designed for 100 Gbps network connections over single-mode fiber and uses an MPO-12 Type B APC connector.
The module supports cable distances up to 2 km when used with OS2 single-mode fiber. Ubiquiti specifies that transmission distance is limited to 500 m when OS1 single-mode fiber is used. The fiber cable is not included.
Technical Information
UACC-OM-QSFP28-PSM4 operates with a 1310 nm transmit wavelength and 1310 nm receive wavelength. The supported data rate is 100 Gbps and maximum power consumption is 3.5 W.
The module uses the QSFP28 form factor and is compatible with QSFP28 and QSFP+ interfaces as specified by Ubiquiti. The optical connection uses an MPO-12 Type B APC connector.
Compatibility
The transceiver is intended for compatible QSFP28 or QSFP+ network interfaces and single-mode fiber infrastructure. For the full 2 km specified distance, Ubiquiti requires OS2 single-mode fiber. With OS1 single-mode fiber, the specified transmission distance is limited to 500 m.
The optical fiber cable is not included with the module. The installed fiber connector and polarity must match the MPO-12 Type B APC interface required by the transceiver.
Key Features
- 100 Gbps PSM4 single-mode optical transceiver
- QSFP28 form factor with QSFP28 and QSFP+ interface compatibility
- MPO-12 Type B APC optical connector
- Up to 2 km over OS2 single-mode fiber
- 1310 nm transmit and receive wavelength
Applications
- 100G data center interconnects
- High-speed enterprise network backbone links
- 100G switch-to-switch connections
