Product Highlights
● Channel Count: It supports up to 18 independent channels, allowing the multiplexing of 18 different wavelengths onto a single fiber.
● Wavelength Range: It operates within the Coarse Wavelength Division Multiplexing (CWDM) range, typically spanning from 1270 nm to 1610 nm. Each channel is allocated a unique wavelength within this range.
● Passive Operation: CWDM multiplexers are passive devices, meaning they do not require any external power supply or active components.
● Plug-and-Play: CWDM multiplexers are designed for simple installation and configuration. They can be easily integrated into existing optical networks without the need for complex setup procedures.

FAQ
1. What is the wavelength of CWDM ?
A: The wavelength range of a CWDM (Coarse Wavelength Division Multiplexing) system typically falls within the range of 1260nm to 1625nm. Each channel in a CWDM system is assigned a specific wavelength within this range, allowing multiple data streams to be combined and transmitted over a single optical fiber. The channels are usually spaced apart by 20nm, resulting in a total of 18 channels in an 18-channel CWDM system. This technology is commonly used in optical networking to increase the capacity of existing fiber infrastructure.
2. How does a CWDM mux work?
A: A CWDM (Coarse Wavelength Division Multiplexing) 18-channel wavelength division multiplexer is a networking device used to combine or separate multiple optical signals that are transmitted over different wavelengths of light.
3. Which is better CWDM or DWDM?
A: The choice between CWDM and DWDM depends on various factors such as the required capacity, distance, cost, and available infrastructure. CWDM is often used for shorter distance communications within a local area network (LAN) or metropolitan area network (MAN) where a lower number of channels are needed. DWDM, on the other hand, is suitable for long-haul and high-capacity applications, such as backbone networks and transcontinental links.
