可调光色散补偿模块 tunable DCM
简单描述
Civcom的Free-path系列动态色散补偿模块包含独立色散补偿模块(TODC)和可管理的色散补偿模块(M-DCM)两种。可以作为陆地和海缆光传输系统中传统DCF的替代产品。TODC系列色散补偿模块可以提供从-1700ps/nm到+1700ps/nm的色散补偿值,适用于速率到12.5Gbps的光传输系统。M-DCM色散补偿模块的采用可以降低对光放大器色散性能的要求,可以在线管理系统的色散,支持100km的色散补偿。
详细介绍

M-DCM-10G-SC is an integrated Tunable Optical Dispersion Compensation Module for 10Gbps RZ and NRZ applications.
It is used for a pre or post compensation of a single channel and can be used as DCF replacement for Submarine applications.
The M-DCM-10G-SC is based on Civcom standard 16PIN butterfly sealed packaged TODC that contains Gires-Tournois (GT) etalons cascaded in free-space.
The M-DCM-10G-SC supports both 33GHz and 50GHz spacing in the same device. The device can tune itself either to 50GHz or 33GHz by using the incoming ITU information given by the user.
The M-DCM-10G-SC module is used to compensate for chromatic dispersion values ranging from -800ps/nm to +800ps/nm with operating bandwidth of 32GHz suitable for 10Gbps RZ and NRZ modulation.
The M-DCM-10G-SC introduces a low insertion loss, low power consumption and small size Dispersion Compensation Module. By using a CPU and software commands over RS232, the M-DCM-10G-SC allows remote managing of dispersion, reduces in-line amplification requirements and allows remote managing of dispersion while using a single part number as a substitute to multiple DCF
