Tellabs, Coriant and Infinera and Their Contribution To 7100N

The metro bandwidth is growing strongly which is being driven mainly by the data centre interconnect (DCI), enterprises that are migrating their data centres to cloud and internet videos. The metro network is confronted with numerous unpredictable patterns of traffic. There is a continuous evolution of applications and end-user services. Many networks rely on the 7100 packet optical transport solutions owing to the environment it provides. Tellabs, Coriant and Infinera, all have worked on these 7100 optical networks and have helped it evolve.

Contribution of Tellabs  

In the year 2004 Tellabs was working on the 7100 optical transport system to help the telecom service providers to reduce their total cost of ownership and in the convergence of transport infrastructure. The Tellabs 7100 system aggregated MSPP services and SONET services. These services included Gigabit Ethernet on a single module that could drop or add traffic to the DWDM network. This helped the Telecom service providers to reduce their infrastructure cost by fifty per cent. This was one cost-effective way for the Telecom service providers to deliver their reliable services.

The Tellabs 7100 system offered the telecom service providers capital as well as operating savings in expenses with a remotely reconfigurable optical drop or add multiplexer (ROADM) abilities. However, Infinera brought in a lot of new developments into the 7100 series.

Contribution of Infinera  

Coriant was an organization that delivered great technical value across the network. It also developed the 7100-transport system. However, after its acquisition by Infinera the patent came under the company and further developments were led. The Infinera 7100 series offers a broad range of applications that includes wholesale Ethernet services as well as business, fixed broadband backhauls, mobile backhaul and SDH/SONET migration. It also offers DCI, router interconnect, SAN services, cloud connect, private enterprises network and native video services. They also provide 7100 Nano, 7100 Pico as well as 7100 PSX-3S which can be deployed as standalone pocket switches. There are numerous benefits of the 7100 Nano that can be deployed as SONET/SDH or ROADM. 7100 Nano also supports configurations that combine multiple technologies into a single platform.

Features of 7100N  

Reduces Opex with ROADM-ON-A-BLADE and provisions speed wavelength ‚ÄčThe 7100N supports up to eight degrees of ROADM with over 88 channels that leverage compact ROADM-on-a-blade technology. 

A wide range of Protocols are transported with the help of Muxtransponders and


A wide range of client interfaces ranging from 155 Mbps to 100 Gbps is supported by 7100N.

It also includes SONET/SDH, Ethernet, Fiber Channel, OTN and native videos.

Converge WDM and Feature-rich packet switching into a single platform  

Feature-rich and flexible packet switching is supported by 7100N with the support of MPLS-TP and carrier Ethernet.
