Overview
Optical multiplexers (MUX/DEMUX) and Optical Add-Drop Multiplexers (OADMs) are the passive backbone of any efficient DWDM network. By combining multiple wavelengths onto a single fiber â€" and enabling selective addition or removal of individual channels â€" these devices allow operators to maximize existing fiber assets with zero power consumption and near-zero maintenance overhead.
Master Goods Telecom offers a comprehensive range of passive filters, fixed OADMs, and reconfigurable ROADM platforms that scale from simple two-node links to complex multi-site ring and mesh topologies. Our passive optical solutions are the cost-efficient foundation for any DWDM transport architecture.
Key Features
Fully passive optical filter technology requires no power supply. Eliminates ongoing energy costs and removes a major point of failure from your optical transport layer.
Multiplex up to 96 DWDM wavelengths onto a single dark fiber pair, multiplying the effective capacity of existing fiber infrastructure without new cable deployments.
OADM technology allows individual wavelengths to be added or dropped at intermediate sites while all other wavelengths pass through transparently â€" enabling efficient ring topologies.
Precision thin-film filter technology delivers low insertion loss and high channel isolation, maximizing usable transmission distance without additional amplification.
Available in 4, 8, 16, 32, 40, and 96-channel configurations with 50 GHz or 100 GHz channel spacing to match your existing transponder and network plan exactly.
Available in 1U rackmount, plug-in module, and compact enclosure formats for easy integration into existing equipment rooms, street cabinets, and remote sites.
Product Types
Passive MUX/DEMUX units combine multiple wavelengths from individual transponders onto a single fiber for transmission, and separate them again at the far end. Available for CWDM (20 nm spacing) and DWDM (50/100 GHz ITU grid) wavelength plans.
Passive add-drop units for ring or linear topologies where specific wavelengths must be dropped at fixed intermediate sites. Cost-effective for stable, well-planned multi-site deployments where routing requirements are known in advance.
Software-controlled wavelength routing for dynamic, mesh-topology networks. Enables colorless/directionless/contentionless (CDC) add-drop for maximum operational flexibility, remote wavelength provisioning, and automated traffic restoration.
