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.

The demand for an easy-to-install, robust home network is growing due to the availability of higher and higher access speeds into the home. While there are many solutions for a home network, a mixed Plastic Optical Fiber (POF)/WiFi solution is the most ideal for the professional and do-it-yourself installer.
