CWDM System equipments

can efficiently replace cable launching and broaden bandwidth with a low cost. It suits to mid and short distance MAN building,

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.

Features:

l     Protocol: Ethernet, SDH, fiber channel, 3G station etc;

l     Capability: 16 wavelengths (32 wavelengths the most) multiplex, rate in each channel can reach 2.5Gbit/s, total rate 40Gbit/s, transmitted by single mode fiber;

l     Rates: 10Mbps ~ 155Mbps,100M~1.25Gbps, 100M~2.5Gbps, Ethernet, STM-64 and E1 interface;

l     Expansibility: 2~16 wavelengths optional;

l     Network structures: point to point, point to multi-point, chain mode, and ring mode;

l     Fiber access: single mode, and multi-mode;

l     Wavelength access: 850nm, 1310nm, 1550nm;

l     Power supply: AC220V, DC-48V;

l     19” chassis, easy for installation and use;

l     2 transmissions: single fiber bidirectional, and dual fiber bidirectional;

l     With OADM;

l     Open designing, can co-work with equipments made by other manufacturers.

 

 Protecting

l     1+1 protecting to multiplex part, switch time <30ms, it protects data in transmission.

 

Management

l     flexible management configuration;

l     Based on SNMP platform to manage by graphic interface; with the 4 functions IS0/IEC7498-4 mentions.

l     Local management by command line from RS232 serial port.

l     Remote management by command line from Telnet protocol.
