The CommScope OCC1P-TAP-4P-13-S2S2SEB is a 4-port singlemode fiber optic tap/splitter used to distribute optical signal from a fiber optic cable feeder line to multiple subscriber or distribution legs (Millennium Part #545353). Fiber optic taps like this let network designers branch service from a passive optical network without active electronics, supporting efficient FTTH and PON architectures. This model's S2S2SEB connector and split configuration is documented on its manufacturer spec sheet for precise system design. Millennium stocks CommScope fiber optic splitters and taps to help engineers plan and build cost-effective passive fiber distribution networks.
