Rack-mount fiber optic splitters are passive optical splitters integrated into standard rack-mounted chassis, typically installed in telecom racks, ODF frames, or central office distribution systems. The Optical splitter rack mount is designed by standard of YD/T2000-2009, YD/T1117-2001. Optical splitter rack mount is using metal box packaging which can be installed in 19” frame or. 1 x 16, 1 x 32 PLC Fiber Splitter, (Wiki: What is Optical Fiber Splitter?) 1U 19″ Rack Mount, SC/APC, Singlemode, Passive optical fiber splitter PLC (Planar Lightwave Circuit) splitters are Single Mode Splitters with an even split ratio from one input fiber to multiple output fibers. Whether you're working on a telecom project, a data center, or an FTTH network, these tips. A rack mount splitter is a critical networking and telecommunications device designed to divide incoming signals—optical, RF, or IP—into multiple output paths while maintaining signal integrity. These rugged enclosures are offered in a variety of configurations making them ideal to be mounted in centralized splitting locations close to the Optical Line Terminal (OLT) or remote splitting locatio s nearer the Optical Network Unit (ONU).
