Extend POTS Telephone Service Over Fiber
The PK1M-RM POTS-to-fiber converter installation kit provides a practical solution for extending analog telephone service over multimode fiber. It is designed for applications where telephone equipment needs to be connected across a fiber optic link rather than directly over copper telephone cabling.
The FXO unit is installed at the exchange or PBX side, while the FXS unit is installed at the subscriber or telephone side of the connection.
FXO and FXS POTS Interfaces
The PK1M-RM provides one FXO interface and one FXS interface for a single POTS telephone connection.
- FXO: Exchange/PBX side
- FXS: Subscriber/telephone side
- Function: POTS
- Channels: 1
This configuration provides a point-to-point analog telephone connection over fiber.
Multimode Fiber Transmission
The PK1M-RM uses multimode duplex fiber with a fiber transmission capability of up to 2 km. This makes it suitable for extending POTS service between separated buildings, facilities, equipment rooms, or other locations where fiber is used for communications infrastructure.
All units in the 1-channel POTS converter family use LC optical connectors.
Rack-Mount POTS Fiber Installation
The PK1M-RM is designed for rack-mount installation. According to the VERSITRON selector guide, rack-mount kits include one 2-slot chassis and one standalone enclosure, providing flexibility for deploying the telephone converters in a centralized equipment location.
1-Channel POTS to Fiber Applications
The PK1M-RM can be used for:
- PBX-to-remote telephone connections
- Building-to-building telephone links
- Centralized telephone equipment installations
- Remote POTS extensions
- Commercial and industrial facilities
- Fiber-based communications infrastructure
- Applications requiring rack-mounted telephone fiber converters
