Extend POTS Telephone Service Over Fiber
The PK1M POTS-to-fiber converter installation kit provides a practical way to extend analog telephone service beyond the normal reach of copper cabling. Fiber optic transmission provides a physical separation between the telephone equipment at each end of the link while extending the connection over a multimode fiber infrastructure.
The PK1M is designed specifically for POTS applications, with an FXO unit installed at the exchange or PBX side and an FXS unit installed at the subscriber or telephone side.
FXO and FXS POTS Interfaces
The PK1M installation kit includes:
- 1 FXO interface for the exchange/PBX side
- 1 FXS interface for the subscriber/telephone side
- POTS voice service over fiber
- Multimode duplex optical transmission
This configuration provides a complete point-to-point fiber link for extending a two-wire analog telephone connection.
Multimode Fiber Transmission
The PK1M uses multimode duplex fiber and supports distances up to 2 km, making it suitable for extending POTS service between buildings, facilities, equipment rooms, or other locations where copper telephone cabling is not practical.
All units in the PK1M family use LC optical connectors.
Standalone Installation
The PK1M is configured for standalone installation, making it well suited for individual point-to-point telephone links without requiring a rack-mounted chassis.
For applications requiring rack installation, VERSITRON also offers the PK1M-RM, which provides the same 1-channel POTS, multimode duplex, 2 km configuration in a rack-mount installation.
1-Channel POTS to Fiber Applications
The PK1M can be used wherever an analog telephone connection needs to be extended over multimode fiber, including:
- Building-to-building telephone connections
- PBX-to-subscriber connections
- Remote telephone extensions
- Campus and facility communications
- Industrial and commercial facilities
- Communications between separated equipment locations
