Ubiquiti UACC-CWDM-4 Rack-mountable 4-channel 1270 to 1330

Ubiquiti UACC-CWDM-4 4-Channel CWDM Mux Demux

Overview

The UACC-CWDM-4 is a rack-mountable coarse wavelength division multiplexer and demultiplexer designed to increase capacity of existing single-fiber infrastructure. This accessory enables simultaneous transmission of four independent channels across a single strand of SMF-28e fiber using distinct wavelengths (1270, 1290, 1310, 1330 nm). Channel isolation reaches 30 dB adjacent and 40 dB non-adjacent, ensuring reliable signal separation. Rated for 500 mW maximum power handling with 50 dB return loss and minimal passband ripple (0.3 dB), the unit operates across -30 to 75°C and stores safely to -40 to 90°C. NDAA compliant.

Compatibility

Integrates with UniFi UISP and broader Ubiquiti ecosystems supporting fiber-based transport. Connects via LC/UPC connectors (1270–1330 nm range, SMF-28e pigtails ≥0.5–1 m). Suitable for network integrators, telecom installers, and IT teams expanding capacity on existing dark fiber or carrier-grade links.
