Features Specifications: Chassis CWDM optical transmission system (with NMS), 2U+1U,19"

Visint CWDM system brings a full range of management and high availability solutions for customers deploying mission-critical networks. Flexible and scalable, Visint CWDM solutions support DS3, Ethernet, fibre-channel, SONET/SDH protocols as well as line protection and restoration. CWDM provides a low cost, high bandwidth solution for bringing the benefits of fiber-optic technology to the curb, business, and home. It allows users to increase the capacity of existing fiber by utilizing widely spaced, separate wavelengths (1310nm-1610nm) within the same fiber pair.

Chassis flexible 2 U+1U, CWDM active chassis separate from the passive MUX/DEMUX chassis with exellent NMS system can expand to 16 channels at most and convenience for upgrade!

Functional Feature

High Capacity

Apply single mode optical fibre to transmit at present. 8 wave channels of the compact equipments can be multiplexed with maximum rate of 2.5 Gbit/s per channel and a total capacity of 20 Gbit/s. When all-wave fibre is used, the rack-type equipment can be expanded to 32 channels with maximum rate of 10 Gbit/s and a capacity of 320 Gbit/s.

Flexible Networking

Be applicable to network structure of point-point, chain structure, ring structure, bidirectional transmission with single fibre, and point to multi-points.

Flexible Access for Various Rate

Be available for various rate accessing, and support professional network services such as Ethernet, PDH, SDH CATV.

Various Transmission Distance

Point to point transmission distance without relay is 30km,50km,80km,100km,120km and above.

Perfect Expansion

With 2, 4, 5, 6, 7, 8, 16 wave channels, it can be expanded to more than 32 wave channels mixed with DWDM.

With 1+1 protection system for optical multiplexing

The switching time for optical line is less than 30ms, guaranteeing a secure and reliable transmission line.

With 1+1 backup system for heat redundancy of power supply

Open structure, support access and connection of various manufacturers equipment

Transmission with Relay

When transmission distance over 80 KM without delay, various rate can be re-amplified, re-shaped and re-timed with relay equipment, which can extend transmission distance to 300KM.

With functions of Optical Add/Drop Multiplexing(OADM)
