End Network Headaches 18 Channel CWDM MUX DEMUX LGX Plastic Box with Simplex BIDI for Low Loss Connectivity
This high-density 18-channel CWDM MUX/DEMUX module is engineered for cost-effective wavelength division multiplexing in fiber-optic networks. Housed in a lightweight LGX plastic enclosure, it combines space-saving 1U rack-mount compatibility with durable, corrosion-resistant design, ideal for budget-conscious deployments. Featuring simplex BIDI (bidirectional) transmission, it enables single-fiber operation, doubling fiber capacity and reducing infrastructure costs for legacy systems.
Compliant with ITU-T grid standards, the module ensures precise wavelength spacing across 18 channels (1271~1611nm) for seamless compatibility with CWDM transceivers. With ultra-low insertion loss (<1.5dB) and high channel isolation (>30dB), it maintains signal integrity in metro access, enterprise networks, or FTTx applications. The integrated design supports easy installation and real-time monitoring without service disruption.
Optimized for scalability, this CWDM solution is perfect for telecom operators, ISPs, and data centers seeking to expand bandwidth on limited fiber resources. Keywords: 18-channel CWDM MUX/DEMUX, simplex BIDI transmission, LGX plastic box, ITU grid, low insertion loss. Backed by rigorous testing, it meets industry certifications for reliability in harsh environments.
Ideal for: Single-fiber network upgrades, cellular backhaul, and high-capacity video distribution systems requiring compact, plug-and-play wavelength management.
Simplex CWDM MUX and DEMUX
Multiplexer (MUX) and demultiplexer (DEMUX) are combined together into a single piece of equipment for bi-directional data transmission over one fiber.
Simplex Bi-Directional Transmission should be used in pairs, MUX/DEMUX Portfor specific wavelength must be opposite CWDM
HJY CWDM Mux/Demux is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10Gbps Ethernet at 1590nm). This allows for long-term future proofing of the networking infrastructure because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed.
HJY provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer (OADM) units to suit all applications such as: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV. And we provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice.
Maximize Your Fiber with WDM Network
A single fiber can be shared for multiple different data or services in WDM network. It maximizes the usefulness of fiber and generates substantial savings.
Mix of Services Multiplexing at Any Rate
Flexible mix of 1G/10G/25G/40G/100G/200G Ethernet, 8G/16G FC, SAN, OTN, SDH/SONET and native video services, it's transparent to any rate, any service multiplexing and upgrade
