The latest CWDM technologies (standardized ITU-T are intended to handle a problem of lack of transportation resources at the operator networks and corporate communication networks and to open a possibility for rendering new services.
-
Transmission of up to 40 Gbit/s (4 x 10 Gbit/s) through one optical fiber, up to 80 Gbit/s through a pair of optical fibers;
-
Highly flexible and scalable module architecture;
-
Openness for “colored” interfaces (according to ITU-T G.694.2);
-
Possibility of the fixed-length waves transit through the node;
-
“Point-to-point”, “ring”, “line” topology;
-
Possibility of reservation and selection of power supply unit type;
-
2 types of space-saving chassis;
-
Variety of client-side interfaces: STM-4/16/64, Gigabit Ethernet, 10GbE, Fiber Channel 1G/2G, STM-1 transponder with a function of input/output multiplexor and ring protection;
-
Extended functions of network and services management;
-
Functions of remote and local loopback;
-
Function of WDM-connection testing;
-
Support of performance monitoring for all interfaces;
-
Functions of transmission switching-off to the user equipment in case of signal failure;
-
CLI, Telnet, SNMP;
-
Availability of dry contacts for monitoring and control over the terminal facilities (HKA/HKC);
-
Optical account of up to 27 dB (for 2.5 Gbit/s)/26 dB (for 10 Gbit/s). Availability of transponder-regenerator (23 dB)
