Ubiquiti CWDM Mux Demux 8 - 8-channel optical multiplexing

8 wavelengths, 1450–1590 nmDuplex LC/UPCSMF-28eInsertion loss <2.5 dB

The Ubiquiti CWDM Mux Demux 8 (UACC-CWDM-8) is a single, passive rack-mountable unit for multiplexing and demultiplexing eight optical wavelengths from 1450 to 1590 nm. It is designed to increase capacity on existing fibre infrastructure when used with compatible CWDM optics, a matching remote mux/demux and suitable host equipment.

Best For: For fibre-network operators planning an eight-wavelength CWDM link who can provide the matching remote unit, compatible optical modules, duplex single-mode fibre and host switching or aggregation hardware.
Before you order: This is one passive mux/demux, not a complete link or a pair. A matching remote UACC-CWDM-8, wavelength-compatible CWDM modules, suitable host switching/aggregation hardware, duplex single-mode fibre and patching are separate requirements and are not listed as included. Using the optional EXP expansion requires a separate CWDM Mux Demux 4 and compatible equipment at each end. No data rate, reach, aggregate bandwidth, amplification or universal module compatibility is specified.

What's in the Box

  • One Ubiquiti UACC-CWDM-8 eight-channel chassis
  • Two rack mounting ears
  • Eight ear screws
  • Four rack cage nuts
  • Four rack screws

What It Means in Practice

  • The COM connection links another CWDM Mux Demux 8 over a pair of single-mode fibre cables; it is not a one-strand simplex BiDi link.
  • The MON port supports observation using a separate optical power meter or spectrum analyser; neither instrument is listed as included.
  • The EXP port is for linking a separate CWDM Mux Demux 4 to add its four channels; it does not mean an expansion unit is included.
  • The chassis measures 442 × 120 × 43.7 mm and weighs 1.4 kg; check rack and cable-connector clearance for the installation.

What Will Not Work

  • Does not provide active Ethernet switching, media conversion, amplification or regeneration.
  • A second matching eight-channel mux/demux, compatible CWDM optical modules, host switching/aggregation hardware, duplex single-mode fibre and patching are separate requirements.
  • The four-channel expansion unit, rack, optical modules, fibre patch cables, host equipment, power meter and optical spectrum analyser are not listed as included.
  • No data rate, reach, guaranteed aggregate bandwidth or universal optical-module compatibility is specified.

Key Features

 
Eight specified wavelengths
Eight channel ports cover 1450, 1470, 1490, 1510, 1530, 1550, 1570 and 1590 nm.
 
Dedicated monitoring port
The duplex LC/UPC MON port supports observation with a separate optical power meter or optical spectrum analyser.
 
Expansion connection
The duplex LC/UPC EXP port can link a separate CWDM Mux Demux 4 to add its four channels, with compatible equipment and extra patching.

Frequently Asked Questions

Is this a complete two-ended link?
No. The package is one eight-channel unit. A matching remote CWDM Mux Demux 8 and the required optics, host equipment and fibre cabling are separate.
What does the COM port connect to?
It links to another CWDM Mux Demux 8 over a pair of single-mode fibre cables.
Is a CWDM Mux Demux 4 included?
No. The EXP port can link a separate CWDM Mux Demux 4; compatible equipment at each end and extra patching are required.
Does it need power or switch Ethernet traffic?
It is a passive optical unit, not an active Ethernet switch. The reviewed installation sequence shows no power connection.
Singular Expert Insight

This exact eight-channel model carries eight specified wavelengths from 1450 to 1590 nm and provides separate COM, MON and EXP ports. Its passive design avoids treating it as a powered Ethernet switch or media converter.

Buyer’s Guide

✓ Buy it if For fibre-network operators planning an eight-wavelength CWDM link who can provide the matching remote unit, compatible optical modules, duplex single-mode fibre and host switching or aggregation hardware.
✕ Skip it if This is one passive mux/demux, not a complete link or a pair. A matching remote UACC-CWDM-8, wavelength-compatible CWDM modules, suitable host switching/aggregation hardware, duplex single-mode fibre and patching are separate requirements and are not listed as included. Using the optional EXP expansion requires a separate CWDM Mux Demux 4 and compatible equipment at each end. No data rate, reach, aggregate bandwidth, amplification or universal module compatibility is specified.
→ Also consider Plan wavelength matching, compatible optics and the full optical loss budget, including any optional EXP-connected four-channel expansion.
