As telecom networks continue to expand and upgrade towards 400GB and beyond, carrying more and more traffic to meet the demands of the Internet and other applications, the need for proper wireline and fiber installation and maintenance has become more critical. Whether it’s cable certification, fiber characterization, fusion splicing, fiber inspection, or transport testing (Ethernet or legacy systems), getting it right at commissioning and identifying problems quickly is more important than ever before.
Cable certification with LAN Cable Testers meets the requirements of TIA-568-B and ISO 11801:2002 and insures maximum success of in building installations. Fiber characterization helps carriers and enterprises make critical decisions regarding their fiber networks through increased data rates, broader wavelength ranges, component quality checks, and a plethora of application standards. Fiber characterization is complete end-to-end testing that measures overall fiber quality: It measures the properties of a fiber-optic installation for losses, dispersions, and reflections, which enables quick verification of the fiber’s integrity and capacity, and identifies areas that require recommendations for fiber network maintenance and improvements. Full fiber characterization includes connecter end-face inspection, insertion loss measurements, return loss measurements, OTDR testing, chromatic dispersion testing, polarization mode dispersion testing, and spectral attenuation. Fusion splicing—the joining together of two fiber-optic cables or strands—is performed to restore fiber-optic cables that have been damaged during transport or installation. Fiber inspection probes ensure that connectors and adapters are clean and free of defects is where accurate testing starts. Transport testing requires specialized test sets that hook into a LAN/WAN network and analyze its traffic.
