With the explosion of digital traffic and the ever-growing array of bandwidth-hungry applications, OTN (Optical Transport Network) evolves from point-to-point DWDM remedies to scalable and robust optical networking applications that cater to a wide variety of client signals with equally-varied service requirements. Carriers are also placing particular emphasis on OTN in the Metro area, where it is shifted rapidly from SONET/SDH to WDM (wavelength-division multiplexing). With the goal of boosting bandwidth and increasing network functionality, OTN provides a way to support different traffic types in a more cost-effective manner than by using SONET/SDH networks. What is OTN and how will the OTN-based solutions benefit your optical networking?
What Is OTN — Optical Transport Network
It is imperative to clearly define what is meant by the term OTN. OTN is defined by the ITU Telecommunication Standardization Sector (ITU-T). It’s a digital wrapper technology which provides an efficient and globally accepted way to multiplex different services onto optical light paths. The OTN technology or digital wrapper technology provides a network-wide framework that adds SONET/SDH-like features to WDM equipment. It creates a transparent, hierarchical network designed for use on both WDM and TDM devices. OTN integrates functions of transporting, multiplexing, routing, management, supervision, and builds OTN client (e.g. SONET/SDH, IP, ATM) connections in the Metro and Core networks.
Five Key Benefits of OTN Network
OTN network combines the advantages of optical transmission and electrical processing to provide end-to-end, transparent pipe connections, increased spectral efficiency, and large-capacity transmission capabilities for long-haul transmissions. The primary benefits of OTN network are presented as follows.

How to Get a Custom OTN Solution in FS?
FS focuses on designing various optical transmission solutions to make your network farther, faster, smarter. To get a customized OTN solution in FS, kindly submit the following three requirements about your project, then our experienced tech engineers will design the optimal OTN solution tailored to your specific needs.
Q1: How many spans do you have, and how far between each of the span?
The specific distance your network transports will determine the fundamental equipment that is needed. Specifically, the transmission distance between each span will indicate whether the DCM (Dispersion Compensation Module) would be needed to compensate in the fiber optical link.
Q2: What's your fiber type and the link loss (typical 0.25dB/KM)?
Our OTN solutions can be tailored to both dual and single fiber type. And link loss is necessary for collocating the most appropriate optical transceivers and some active components such as EDFA amplifiers.
Q3: What's the data rate between each span? And how many businesses do you plan to transmit?
To make clear the data rate and capacity for each span in your network is conductive to choosing the most practical types of MUX or OADM to for your current OTN infrastructure. And a good acquisition of the numbers of businesses you were to deploy can pave the way for future network expansion.
All in all, the OTN technology represents both a technical leap forward in optical networking over SONET/SDH and a business opportunity for carriers and service providers alike. OTN networks can fully leverage the transport infrastructure in the era of data/transport convergence by offering carriers unprecedented architectural flexibility, client-protocol independence, and service differentiation.
