Recently, there has been a lot of information distributed in the industry regarding latency in optical transport systems. This white paper takes an objective look at what really causes latency in transport systems and what to look for in a transport system designed for low latency.

High Quality video distribution made simple and cost effective ! Read about our high quality video distribution products designed for the secure and reliable transport of high definition video.

Increasingly, content providers and production companies are looking for transport of uncompressed digital video signals, regardless of format, over long distances without degrading the original quality. Production companies are now starting to digitally transfer SDI and HD SDI content over fiber for purposes of pre and post-production, editing, and distribution, live or otherwise.

Don't be held hostage by your legacy transport vendor ! The cost of upgrading transport systems has come down dramatically over the past few years. Newer generation transponders are designed to be deployed over existing line systems allowing you to take advantage of these cost improvements now instead of after you have filled your current line system to capacity.

In recent years, there has been a lot of focus on wireless backhaul access networks that take data from the towers and carry it back to a metro and core network. What has been overlooked is the potential for CAPEX savings in the metro and core portions of the wireless backhaul network. The broad mix of protocols and rates in these networks requires advanced multiplexing and aggregation capabilities that are just starting to be seen in the market.

It has been at least eight years since transport equipment vendors started talking publically about 40G solutions. Yet 40G has made little progress achieving acceptance in the market. Why in all this time has 40G not been able to displace 10G in the market ? The answer is simple. To date, 40G solutions offered by industry equipment vendors are not economicallyl sensible. Given this, other than a number of feasibility experiments, 40G deployments have been limited. Now, finally, there is a 40G solution ready for market, the Ekinops 40G WaveBonding® solution.

The move to Ethernet has come a long ways in reducing the overall cost of infrastructure, particularly when delivering business Ethernet service to customers. As an industry, however, we have now entered the second phase of the migration to Ethernet. In the first phase we achieved significant growth and savings through the introduction of Ethernet services. In the next phase we will find ways to more cost effectively deliver Ethernet as a native service and in conjunction with other service types. As popular as Ethernet is, service providers still need to deliver native TDM service and TDM traffic for backhauling other applications that have not fully migrated to Ethernet (legacy digital loop carriers, DSLAMS, and cell tower’s that still use ATM for instance).

Companies in many industries are now required by both regulatory and business needs to implement a plan for disaster recovery and business continuance. These plans call for data replication of critical information across a geographically dispersed Storage Area Network (SAN). In addition to being used for disaster recovery, these SAN networks are also used to replicate data allowing for local copies at distributed locations for performance reasons and for databases in which data is geographically diverse (different data stored at different locations). Data replication requires a transport system that can handle large amounts of data. For that reason, having fiber between data centers is the ideal solution, especially in cases of extended distance between sites. In the event that fiber is not available, a high-speed SONET/SDH line will provide a good alternative.

ROADMs are a disruptive technology that have and will continue to benefit the industry in many ways. ROADM technology allows Service Providers network flexibility without major up front planning or future reconstruction of the network to accommodate unforeseen service demand. In addition, ROADM technology holds a very promising future in the realization of all optical switching and protection.

The move to Ethernet as a backhauling technology for DSLAMS and broadband digital loop carriers (DLCS) has come a long ways in reducing the overall cost of access infrastructure. There are however still many inefficiencies in the way that we build transport networks for backhauling access traffic that add unnecessary cost to this infrastructure. In addition, the migration to IP/Ethernet as a backhaul technology has created a temporary issue in that for some time we will still have both TDM and Ethernet traffic to deal with creating a need for more efficient multi-protocol multiplexing in access infrastructure.
