Single Fiber 4 Channel DWDM Mux Demux

The 100 GHz C21–C24 LC/UPC single-fiber A-FMU plug-in module delivers four independent, high-speed channels over one fiber strand. Its dense wavelength division multiplexing (DWDM) design makes it an optimal choice for demanding network environments, including FTTH (Fiber-to-the-Home) deployments, metro aggregates and access rings.

Low Insertion Loss for Maximum Signal Integrity

Typical Insertion Loss: 2.75 dB

Engineered to minimize optical attenuation, this module preserves signal strength across long spans.

Ensures error-free data transmission and robust link budgets, even under challenging link conditions.

Superior Channel Isolation

Adjacent-Channel Isolation: ≥ 30 dB

Non-Adjacent-Channel Isolation: ≥ 35 dB

Guarantees each wavelength operates independently, eliminating crosstalk in high-density DWDM systems.

Delivers clean, interference-free performance when multiple channels coexist on the same fiber.

Rugged, Passive Design for Long-Term Reliability

Completely passive construction with no electrical power requirements.

Power Handling Capacity: up to 300 mW per channel-supports high-power optical links without degradation.

Built for continuous operation in harsh environments, with an expected service life of five years.

Backed by a comprehensive warranty for peace of mind and minimal maintenance overhead.

Scalable, Future-Ready Integration

Features expansion ports and advanced monitoring interfaces to simplify network upgrades.

Seamlessly integrates into existing DWDM infrastructures, allowing incremental capacity additions as traffic demands grow.

Ideal for service providers and enterprises planning phased rollouts of next-generation optical networks.

With its combination of low loss, exceptional isolation and passive reliability, this plug-in FMU module provides a cost-effective, scalable solution for any high-capacity DWDM application. Its robust specifications and flexible design ensure that operators can confidently meet today's bandwidth requirements while preserving the option to grow.
