CWDM Optical Transmission System(2U+1U)

CWDM Optical Transmission System(2U+1U)
Product Detailed
Active CWDM 2U+1U rack-type systems applies the structure that is flexible to expand. It supports modular upgrade online.

Active CWDM  2U+1U rack-type systems applies the structure that is flexible to expand. It supports modular upgrade online.

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 ,fiber-channelmSONET/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 exisiting fiber by ultilizing widely spaced,separate wavelengths (1310nm-1610nm) within the same fiber pair.

 Up to different channels can be combined on a single fiber pair by Visints  Vispace 1000 active box-type CWDM system, 1U 19

Function feature

High capacity

Apply single mode optical fiber to tansmit at present. 8 wave channels of the compact equipments can be multiplexed with maximum rate of 2.5Gbit/s and a capacity of 320Gbit/s

 Flexible networking

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

 Flexible Access for various Rates

Be available for various rate accessing, and support professional network services such as Ethernet, PDH, SDH, and 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 backup protection system for optical multiplexing.

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

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

 Open structure, supports access and connection of  various manufactures, equipment.

  Transmission With Relay

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

  With the function of Optical Add/Drop Multiplexing(OADM)

  Flexible Network Management Configuration and Management Mode
