Mini CWDM Optical Add-Drop Modules

Mini CWDM Optical Add-Drop Modules

CWDM technology is a low cost and simple way to add bandwidth capacity to your fiber network. It is ideal for data centers and telecommunications applications.

CWDM optical modules are available in a variety of sizes. They are based on uncooled distributed-feedback (DFB) lasers and wide-band optical filters.

CWDM technology is designed to increase the capacity of a fiber optic network without adding additional fiber. It uses low-cost, uncooled lasers that have channels at wavelengths spaced 20 nanometers apart. It is cheaper than DWDM, and can handle more signals.

Typically, a CWDM system consists of a multiplexer and demultiplexer that work together to combine and separate different signals on the same fiber optic cable. The capacity of a CWDM network varies depending on the number of Mux/Demux channels. Generally, 2 and 4 channel Mux/Demux are used in point-to-point systems, while 8 and 18 channels are used in loop or multi-point systems.

There are many different types of CWDM Mux/Demux modules. Some have a simplex port, while others have duplex ports. In most cases, a CWDM Mux/Demux is connected to a switch with single-mode patch cables, while in some cases, it is attached to a CWDM SFP transceiver.

DK Photonics offers a variety of different CWDM products, including a Mini CWDM module that provides bandwidth capacity expansion for future network growth in one of the industry’s smallest packages. It is available in 4- or up to 18-channel configurations and is based on free space optics technology.

It also has lower overall insertion loss and better uniformity across the channels, which makes it a good choice for a variety of field situations. It is a great solution for those who have an existing legacy fiber plant and want to increase their network’s capacity without installing more fiber.

The CWDM Mux/Demux system is installed in a rack-mount chassis. The chassis is usually installed in a 19-inch rack, so it can be mounted near the switches that are going to be connected to the Mux/Demux system.

When selecting the CWDM Mux/Demux module, make sure it supports Mini CWDM the transmission wavelengths from 1270 nm to 1610 nm. It also needs to be compatible with the CWDM SFP transceivers that are being used for the system.

DK Photonics offers a variety different CWDM products, including a Multi-Channel CWDM Mux/Demux for up to 16 channels with a 19-inch rack-mount package. It is also available in a single-fiber version, which is perfect for small or medium-sized networks.

Broadcom carries a wide range of Mini CWDM products to fit your network needs. These CWDM products offer a way to expand your network capacity without installing more fiber. They provide higher bandwidth and increased revenue from your legacy fiber plant in one of the industry’s smallest packages.

These CWDM products include a variety of CWDM multiplexers and optical add/drop multiplexers (OADMs). The Optical Multi-Service MUX modules transport up to 16 channels of Ethernet, TDM or SONET over a single fiber CWDM link.

The iConverter CWDM MUXs are protocol and rate transparent to enable Ethernet, TDM or SONET traffic to be transported over a CWDM common link. They also allow you to mix and match wavelength combinations and port configurations to meet your specific application requirements.

This is an excellent option to add additional capacity in a small package that Mini CWDM will save you money on your CAPEX budget. These CWDM MUXs will work with any iConverter copper-to-fiber media converter or fiber-to-fiber transponder to make your network more scalable, reliable and secure.

You can use these CWDM MUXs in conjunction with any iConverter media converter or transponder to support up to 16 channels of Gigabit Ethernet, Fibre Channel, TDM or SONET over a CWDM single-fiber or dual-fiber common link. The iConverter Multi-Service Platform enables you to connect a variety of devices with your existing fiber infrastructure, allowing you to easily deploy new equipment and upgrade your network without needing to change or replace your fiber.

Using the iConverter CWDM OADMs will also help you to reduce your overall costs on your CWDM network by saving you on cable runs and power consumption, as well as by reducing maintenance. These OADMs are designed for high availability and long life spans to give you peace of mind that your CWDM networks will be up and running in the future.

Another product from Broadcom that is available for Mini CWDM is the iConverter 1-Module Passive Chassis, which allows you to securely rack-mount all of your iConverter single-slot CWDM modules in a 1 RU space. This chassis can be wall or DIN-rail mounted with optional mounting kits.
