The model 907 series of CWDMs combine multiple media converters or multiplexer motherboards onto a single fiber-optic cable. All CWDM cards are ITU-T G.694.2 compliant, passive (no electrical power required), and perform as both an optical multiplexer and optical de-multiplexer, allowing for bidirectional communication.

CWDM & DWDM Cards. The CWDM / DWDM Multiplexers / Demultiplexers and Add / Drop Multiplexers increase the bandwidth capacity of existing single fiber or dual fiber infrastructure by multiplexing up to 16 or more independent wavelengths over a fiber optic connection.

CWDM Mux / DeMux Card. The FRM220-CWMD Mux/DeMux are modular design cards that support ITU-T G.694.2 wavelengths between 1271nm to 1611nm in 20nm increments. The FRM220-CWMD modules are protocol and rate transparent allowing different services such as 10G Ethernet, 10GFC, STM-64, OC-192 to be transported across the same fiber link.

2024年2月28日 · Coarse Wavelength Division Multiplexing (CWDM) is a kind of Wavelength Division Multiplexing – a technology used to expand the capacity of fibre optic networks. It enables multiple data streams to be transmitted over different light wavelengths through a single fibre. How does CWDM work?

These credit card sized electronic cards have been designed specifically for use in harsh marine and industrial environments. Their form factor allows for integration into compact enclosures and pressure bottles. There are two primary types of Model 914 systems: 914-X …

2024年5月8日 · CWDM（Coarse Wavelength Division Multiplexing，粗波分复用）：CWDM技术使用的光的波长范围比DWDM更宽，通常为1270nm至1610nm，每隔20nm或40nm一个通道，可同时传输多个光信号。

CWDM & DWDM Cards. The CWDM / DWDM Multiplexers / Demultiplexers and Add / Drop Multiplexers increase the bandwidth capacity of existing single fiber or dual fiber infrastructure by multiplexing up to 16 or more independent wavelengths over a fiber optic connection.

2024年9月16日 · Coarse Wavelength Division Multiplexing is a variation of Wavelength Division Multiplexing (WDM) technology, used to transmit multiple optical signals through a single fiber. Unlike Dense WDM (DWDM), CWDM employs wider spacing between wavelengths, making the equipment less complex and more cost-effective.

Compatible with all Evertz series CWDM Mux and Demux (3400CWDM, 3405CWDM, 7705CWDM) Compact design occupies only one slot in an Evertz 7700/7800 frame per card module; LC/UPC and LC/APC connector options; Fiber protector to prevent connector damage; Applications. Multi-channel transport of video, audio, data, control in fiber limited applications

2025年2月13日 · CWDM ：经济实惠的短距离传输能手. CWDM 技术采用 20nm 的宽通道间隔，在 1270nm-1610nm 的波长范围内支持 18 个波长。这种宽松的波长间隔使得 CWDM 系统对激光器的波长精度要求较低，从而大大降低了成本。此外， CWDM 器件通常无需冷却，功耗也更
