The Single Fiber 4-Channel Mux/Demux integrates seamlessly into our metro network. Signal stability and low insertion loss have been impressive.
Reliable CWDM mux solution with consistent optical performance and easy deployment.
Compact and efficient unit delivering stable wavelength aggregation across single fiber links.
Excellent signal integrity and minimal loss in production environment.
Cost-effective CWDM deployment with dependable uptime.
Stable optical multiplexing performance with straightforward installation.
The CWDM-MUX-4-SF2 is a compact, single-fiber coarse WDM device that multiplexes and demultiplexes four CWDM wavelengths (1271 nm, 1291 nm, 1311 nm, 1331 nm) onto a single fiber.
By combining four distinct optical channels onto one fiber, the CWDM-MUX-4-SF2 quadruples transport capacity without additional fibers, reducing infrastructure costs.
It supports four standard CWDM ITU-T G.694.2 wavelengths: 1271 nm, 1291 nm, 1311 nm and 1331 nm.
Typical channel insertion loss is 1.7 dB max, ensuring low attenuation and maintaining high optical signal-to-noise ratio.
Channel isolation exceeds 30 dB adjacent and 40 dB non-adjacent, minimizing cross-talk between wavelengths.
Standard SC/APC or LC/APC connectors are available on customer request for optimal return-loss performance.
Single-mode G.652.D fiber is recommended to ensure optimal pass-band characteristics and minimal dispersion.
With typical network power budgets, the device supports up to 40 km transmission without optical amplification.
Operating temperature spans –20 °C to +70 °C, suitable for indoor and moderate outdoor environments.
Yes, you can cascade additional CWDM Mux/Demux units to support up to 18 channels on a single fiber.
While optimized for CWDM, it can interwork with DWDM using external demultiplexers if ITU-T wavelength grids align.
Yes, the Single Fiber design employs bi-directional ports, enabling transmit and receive on each CWDM channel.
Ideal for metropolitan networks, fiber to the home (FTTH), campus backbones and enterprise ring architectures.
Mount in a rack or wall box, connect SC/APC or LC/APC patch cords, and verify channel wavelengths with a fiber tester.
Unit dimensions are 88×44×17 mm and weight is 0.12 kg, offering a low-profile form factor for tight spaces.
No external power is required; the device is fully passive, ensuring zero power consumption and high reliability.
