DWDM : TJ3500

High density Programmable C/DWDM Platform

Overview: The TJ3500 is a versatile, multi-service and multi-reach C/DWDM product that works as a high density traffic aggregator that can support up to 80 10G channels. TJ3500 belongs to the TJ3000 family of intelligent, high-capacity range of manageable C/DWDM transport products.

Ideal Environment: Metro Core for mobile backhaul, high-speed internet, cable mso, storage area network and Business Ethernet applications.

Key Benefits : Mixed Mode Operation Can simultaneously supports CWDM and DWDM technologies on the same chassis, single and dual fiber designs.

Energy Efficiency : Advanced transponder designs to consume as low as 10W per 10GbE.

Carrier Ethernet Switching : Integrates packet aggregation modules with carrier-grade Ethernet OAM/SLA support for MEF based Business Ethernet services

Flexibility : Supports pluggable SFPs and XFPs on both client and line-side interfaces. TJ3000 can deliver 10Gbps rates on both CWDM and DWDM interfaces.

Upgradability : Allows smooth and non-disruptive scaling from a 4 channel CWDM to an 80 channel DWDM in incremental steps

Redundancy : Power Supply and cooling fans are redundant and hot swappable. Control Unit failure does not cause traffic disruption

Programmable interfaces : Support for different types of cards in the same slot that can be programmed by the user
