The PLC (Planar Lightwave Circuit) is a type of optical splitter which uses planar technology and provides low insertion loss, uniformly dividing the optical signal from an input fiber in two or more output fibers. These non-wavelength selective optical splitting devices are supplied with HLGX metallic case which includes pre-installed adapters, input with 1,6mm jacket (connectorized or not), pre-cabled and connectorized SC/APC outputs. Usually used in street cabinets like PFS4, SCP in point-to-multipoint topologies (PON networks). These products have been developed upon TIM or OPEN FIBER technical specification.
