FS Optical Transport Network Platform Unveiling

Updated on Sep 14, 2018

The explosive demand for higher bandwidth, larger capacity and longer distance transmission is driving a significant change in optical networks, which addresses a unified, stable and efficient network that can cost-effectively scale. The OTN network emerges as the ideal choice - it is gaining momentum in the market with reduced transport costs and enhanced network performance. FS newly launched the multi-service WDM transport network platform and it is built to suit the OTN system. Let’s take a look at how FS OTN/WDM-based solutions benefit your OTN architecture.

Why Is OTN Network Imperative?

OTN, or Optical Transport Network, is a digital wrapper that provides an efficient and globally accepted way to multiplex different services onto optical light paths. The OTN technology creates a transparent framework to efficiently carry diverse traffic types, including Ethernet, storage, digital video, as well as SONET/SDH. The OTN creates a transparent, hierarchical network designed for use on both WDM and TDM devices – it boasts distinct advantages like cost-effectiveness, ease of implementation, and simplicity for the evolving network needs. The OTN network hence holds a critical role in scaling the network to 100G and beyond, ensuring an open and programmable network platform.

Aside from effectively reducing operation and capital expenses and increasing the scalability of WDM systems, the OTN network also showcases the following benefits:

 simpler than SONET/SDH
 optimized for carrier WDM networks
 scalable for higher rates
 cost-effective for transporting wide and storage area network (WAN/SAN) protocols
 extended reach between difficult nodes
 transparent delivery of client signals.

FS OTN Network Transport Platform: Compact Size & Full Service

The OTN network provides multi-service transport and large capacity that is ideal for metro network applications. To this end, FS has launched the high integration FMS WDM Transport Network for easier OTN deployment. The multi-service WDM transport network, being an innovative “case-shaped”, all-in-one OTN solution, supports a broad range of services such as SDH/SONET, PDH, Ethernet, SAN, LAN, video. It offers enough flexibility in any network topology (end to end, mesh, ring) with the ideal scalability. This WDM/OTN system combines the OTN switching and WDM features and provides unified transmission of all services: it integrates WDM devices such as CWDM/DWDM equipment with OTN function cards (EDFA, DCM, OEO) in a 2U or 4U form factor, making large-capacity WDM device compact. Note that FS WDM transport platforms do not include OPM, OPD, OLP and OSW cards, if you need any of them, kindly consult sales at sales@fs.com.
