Product Description
The Subframe Optical Splitter combines a rack-mounted chassis with a cassette-type PLC splitter to simplify optical signal distribution and fiber management. It divides an incoming optical signal into multiple outputs, allowing a single feeder fiber to serve multiple network endpoints in passive optical access systems.
The chassis is made from aluminum-zinc-magnesium coated steel sheet, while the internal splitter cassette uses ABS material. High-precision ceramic ferrules and adapter sleeves support reliable optical connections, making the assembly suitable for telecommunications equipment rooms and centralized fiber distribution installations.
Multiple splitting ratios are available to accommodate different subscriber capacities and network architectures. The appropriate configuration depends on the required output count, optical link budget, connector interface, and rack space available at the installation site.
Configuration Options
The Subframe Optical Splitter can be configured with different splitter ratios, connector interfaces, and polishing types to match specific network requirements. Available connector options include FC, SC, LC, and ST, with PC, UPC, or APC configurations depending on the selected connector.
When selecting a model, consider the required splitter ratio, insertion loss, return loss, operating wavelength, rack dimensions, and compatibility with existing optical distribution equipment. The 1×64 and 2×64 configurations use a taller enclosure than the standard 1U models.
