Optical Express from the Edge to the Core

Enabling Significant Cost Savings and Simplified Operations


In response to the exponential rise in bandwidth requirements, network operators are looking for ways to economically grow networks. Optical express capabilities offer the most cost-effective solution to scale transport networks by providing the ability to pass signals through locations purely in the optical domain. Optically expressing signals provides 10x the savings over electrically expressing (terminating the signal, passing it through an IP, Ethernet, OTN, or SONET/SDH electrical matrix, and retransmitting the signal). Reconfigurable Optical Add/Drop Multiplexers (ROADMs) facilitate and automate optical express even in the most complex transport networks and include critical features such as per channel power balancing, variable gain amplification, wavelength selectable switching, and an integrated optical supervisory channel for remote management.

Coriant's comprehensive product portfolio offers ROADM capability through highly integrated and cost-effective network edge solutions to high performance and flexible core network solutions. ROADM options are available on the 7100 Nano™ Packet Optical Transport Platform, the hiT 7300 Multi-Haul Transport Platform, and the mTera® Universal Transport Platform. Leverage all the benefits of optical express and ensure the smooth operation of your network now and into the future with Coriant ROADM solutions.
