8 Channel CWDM Mux Demux 1U Rack Duplex LC/UPC 1470-1610nm Fiber Optic WDM Module

HJY 8 Channel CWDM Mux Demux is a passive optical wavelength division multiplexing module built in a rugged 1U 19 inch rack mount chassis. It multiplexes eight CWDM channels from 1470nm to 1610nm onto a single dual fiber pair and demultiplexes them back at the far end, allowing one optical link to carry eight independent services simultaneously. The duplex LC/UPC interface delivers plug and play installation for telecom central offices, enterprise data centers, campus backbone networks and metro access rings.

The module is housed in a standard 1U 19 inch rack enclosure with dimensions of 44mm (H) x 440mm (W) x 230mm (D) and a net weight of approximately 1.2kg. The front panel is equipped with duplex LC/UPC adapters for the line, express and monitor ports. Mechanical details are shown in the drawing below; the drawing illustrates the housing dimensions and mounting hole positions so that the unit can be installed into any standard 19 inch equipment cabinet without modification.

• 8 Channel CWDM Capacity: Multiplexes and demultiplexes eight full CWDM channels from 1470nm to 1610nm with 20nm channel spacing, expanding a single dual fiber pair into eight independent service channels.
• Duplex LC/UPC Interface: Factory terminated duplex LC/UPC connectors provide reliable, low loss connections and are compatible with standard patch cords used across telecom and data center networks.
• 100% Passive Design: No electrical power, cooling or active electronics are required, delivering an extremely high MTBF and maintenance free operation for years of continuous service.
• Low Insertion Loss & High Isolation: Advanced thin film filter (TFF) technology keeps insertion loss low while adjacent channel isolation is maintained above 30dB, protecting signal quality on long spans.
• Flexible Port Configuration: Monitor port, express port and 1310nm passband port options allow live network testing, channel bypass and legacy service integration without disturbing traffic.
• Protocol Transparent: The module carries 1G/10G/25G/40G/100G Ethernet, 8G/16G Fibre Channel, SDH/SONET, OTN, ATM and video services at any rate without conversion.
• Grade A Manufacturing: Produced in an ISO 9001 facility with 100% factory testing, each unit carries a unique traceable serial number and a limited lifetime warranty.

Note: Specifications are measured with connectors. The drawings shown here only illustrate the dimensions and do not reflect the specific port configuration of each module.

This 8 channel CWDM Mux Demux is ideal for dual fiber point to point and ring topologies where multiple services share one fiber pair. Typical deployments include metropolitan area networks, campus and enterprise backbone links, ISP and carrier aggregation sites, SAN and data center interconnect, FTTH head end systems, private network expansion between buildings, and CATV or video transport backhaul. Because the unit is protocol transparent, network operators can mix Ethernet, Fibre Channel and legacy TDM services on the same fiber pair today and simply add new wavelengths tomorrow when bandwidth demand grows, protecting the existing cabling investment and avoiding expensive new fiber construction.

Each module is individually packed in anti-static protective material with foam cushioning inside a sturdy export carton, ensuring safe delivery worldwide. Neutral packing or OEM branded packaging with custom logos is available on request. HJY provides a compatibility guarantee and a limited lifetime warranty on all CWDM products. Every unit is 100% tested before shipment and records a unique traceable serial number. Our quality system is certified to ISO 9001 and all products fully comply with CE, RoHS and FCC requirements, giving system integrators and network operators complete confidence in long term reliability.
