CWDM:
Coarse Wavelength Division Multiplexing equipments (called CWDM below), can efficiently replace cable launching and broaden bandwidth with a low cost. It suits to mid and short distance MAN building, especially for those operators who are lack of fiber resources. Shenzhen Lingri technolog according to the needs of market, develops LRW-10000 series CWDM equipments, to multiplely transmit signals with wavelengths interval 20nm into a fiber or a pair of fiber. It can support point to point, point to multi-point, chain mode, and ring mode applications etc.
CWDM equipment applies the structure that is flexible to expand. It supports modular upgrade online, and realizes the capacity expanding and maintenance easily. The interface of customer service can be optical fiber port and RJ45 Ethernet port.
