Description
The Transition CAPTF3311-115 is a specialized media converter that bridges analog telephony with modern fiber optic networks. It allows for the integration of traditional Plain Old Telephone Service (POTS) lines and analog phones into a network infrastructure extended by fiber optics. The device features an RJ-11 FXO port, which connects to a central office or PBX trunk line, and an RJ-11 FXS port, designed to connect directly to an analog telephone, fax machine, or modem. In addition to its voice capabilities, the CAPTF3311-115 includes a 100Base-FX multimode fiber optic port with an SC connector. This enables the transmission of both voice and data signals over fiber optic cable, extending the reach of the analog phone connection and the network up to 2 kilometers. This is particularly useful for connecting remote offices, campus buildings, or extending analog phone services where copper cabling is impractical or insufficient. The converter is designed for straightforward deployment, often used in scenarios where legacy analog voice equipment needs to interface with IP-based networks or where analog phone lines need to be extended over long distances. Its compact form factor and included power adapter facilitate easy installation in various locations, providing a cost-effective solution for voice and data convergence over fiber.
