cwdm system solution
this solution is a new broadband access for ftth/fttp, with which 8 channels of signal can transmit in a single fiber, especially suitable for broadband access in building and residential area. the features are: point-to-point communication, saving fiber, convenient installation, information safety, flexible port connecting.
it's common that transmitting 4/8 signals with a fiber, which is superior than setting fiber directly. 4/8 signals are independent and don't disturb the others.
this solution is a new broadband access for ftth/fttp, adopting rack cwdm device c5008s, which can insert 8 different cwdm media converter module cards in maximum, supports hot plugging and don't need complicated debugging.
3、good security of information
every signal is independent and don't disturb the others, can serve as private network for different users.
4、flexible port connecting
in this solution, c5000 series of cwdm rack can provide kinds of ports, including sonet／sdh、atm、ethernet、fiber channel and data, make up a whole cwdm access with w520x/w510x and such kind of cwdm module card.
in this solution, the connections of two ends are different in consideration of convenient connection and location environment. generally speaking, rack cwm is put in master motor room, and insert media converter card in rack, which needs little space and can be managed easily. as for the user access point, we adopt passive cwdm device to device different cwdm signals, and connect to corresponding cwdm media converter make the user access and management conveniently.
