Since the introduction of coherent technologies, the cost of high speed optical transport has declined at a rate unsurpassed in the history of the industry. One of the benefits of coherent technology is that it allows high speed channels to operate over links that, in the past, have not even be able to support 10G, giving it an enormous advantage from a cost / performance standpoint. In today’s market, 100G transport is available at the cost of what 10G was only a few short years ago while 200G is beginning to make inroads into metro-access and even metro-regional networks. This paper explains how Ekinops, a leader in deploying high speed 100G and 200G “alien wavelengths” on existing line systems, can boost the transport capacity of your existing network without impacting existing services at a cost point that makes advances your business case from concept to reality.

This white paper looks at a new approach to building the metro optical layer based on miniaturizing optical layer functions (e.g. amplification, monitoring, wavelength selective switching, and optical supervisory channel) into compact pluggables. In addition to exploring pluggable optical layer use cases, this white paper examines the benefits of pluggables and provides comparisons with traditional approaches, including individual modules and system-on-a-blade architectures as well as fixed WDM and ROADM.

Aerial fiber plays an important role in the global fiber infrastructure. While cheaper to deploy compared to buried fiber, an obvious challenge for aerial fiber is the exposure to harsh environmental conditions, including thunderstorms. While legacy direct detect transmission technology such as 10Gbps is inherently immune to perturbations caused by severe weather, coherent technology with bit rates exceeding 100Gbps presents new challenges. This white paper discusses the physics of fiber perturbations due to lightning strikes, the resulting challenges for coherent transponders, and how new technology solutions deliver superior resilience to adverse conditions.

Sometimes ProLabs hears that a network equipment manufacturer’s sales representative has threatened a customer (which could be an end user, reseller or system integrator, etc.) that if they install third-party transceivers in the system, this will void the system manufacturer’s warranty. In this way, the sales representative tries to coerce customers into purchasing transceiver modules from the same system manufacturer, usually at much higher prices than ProLabs charges. Someone may use this type of warranty threat to spread fear, uncertainty and doubt in the minds of consumers, rather than to compete on the basis of quality and price.

Adoption of Centralized-Radio Networks (C-RAN or Cloud-RAN) has been on the rise as operators are busy increasing bandwidth of mobile communications networks to keep up with ever-increasing demand brought about by the explosive growth in mobile data traffic.
