Questions & Answers
What is the CWDM-MUX-4-SF2 Single Fiber 4-Channel Mux/Demux?
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.
How does the CWDM-MUX-4-SF2 improve network capacity?
By combining four distinct optical channels onto one fiber, the CWDM-MUX-4-SF2 quadruples transport capacity without additional fibers, reducing infrastructure costs.
Which CWDM wavelengths are supported by CWDM-MUX-4-SF2?
It supports four standard CWDM ITU-T G.694.2 wavelengths: 1271 nm, 1291 nm, 1311 nm and 1331 nm.
What is the typical insertion loss per channel?
Typical channel insertion loss is 1.7 dB max, ensuring low attenuation and maintaining high optical signal-to-noise ratio.
What channel isolation does the device offer?
Channel isolation exceeds 30 dB adjacent and 40 dB non-adjacent, minimizing cross-talk between wavelengths.
Which connector types are available?
Standard SC/APC or LC/APC connectors are available on customer request for optimal return-loss performance.
What fiber type is required for installation?
Single-mode G.652.D fiber is recommended to ensure optimal pass-band characteristics and minimal dispersion.
How far can CWDM-MUX-4-SF2 transmit optical signals?
With typical network power budgets, the device supports up to 40 km transmission without optical amplification.
What are the operating temperature ranges?
Operating temperature spans –20 °C to +70 °C, suitable for indoor and moderate outdoor environments.
Can I expand beyond four channels?
Yes, you can cascade additional CWDM Mux/Demux units to support up to 18 channels on a single fiber.
Is the CWDM-MUX-4-SF2 compatible with DWDM systems?
While optimized for CWDM, it can interwork with DWDM using external demultiplexers if ITU-T wavelength grids align.
Does the device support bi-directional transmission?
Yes, the Single Fiber design employs bi-directional ports, enabling transmit and receive on each CWDM channel.
What applications are ideal for this Mux/Demux?
Ideal for metropolitan networks, fiber to the home (FTTH), campus backbones and enterprise ring architectures.
How do I install the CWDM-MUX-4-SF2?
Mount in a rack or wall box, connect SC/APC or LC/APC patch cords, and verify channel wavelengths with a fiber tester.
What are the device dimensions and weight?
Unit dimensions are 88×44×17 mm and weight is 0.12 kg, offering a low-profile form factor for tight spaces.
Does the CWDM-MUX-4-SF2 require power?
No external power is required; the device is fully passive, ensuring zero power consumption and high reliability.
