Extend POTS Telephone Service Over Singlemode Fiber

The PK8S-RM POTS-to-fiber converter installation kit provides a practical solution for extending analog telephone communications over long-distance singlemode fiber. The system connects POTS telephone equipment across a fiber optic link, allowing telephone service to be extended well beyond the normal limitations of copper cabling.

The PK8S-RM is designed for singlemode duplex fiber transmission up to 20 km, using the appropriate length of fiber optic cable.

FXO and FXS POTS Connectivity

The PK8S-RM uses an FXO/FXS configuration for connecting POTS telephone equipment across the fiber link.

  • FXO: Exchange/PBX side
  • FXS: Subscriber/telephone side
  • Function: POTS
  • Fiber: Singlemode
  • Fiber configuration: Duplex

The selector guide specifies one FXO and one FXS interface for the PK8S-RM.

Long-Distance Singlemode Fiber Transmission

Singlemode fiber makes the PK8S-RM suitable for longer-distance POTS communications. The model is specified for a distance capability of up to 20 km over singlemode duplex fiber when the appropriate fiber optic cable is used.

All VERSITRON units in this POTS converter family use LC optical connectors.

Rack-Mount POTS Fiber Installation

The PK8S-RM is specifically designed for rack-mount installation. The selector guide notes that -RM models indicate rack-mount versions, and rack-mount kits include a 2-slot chassis and one standalone enclosure.

For standalone installations, the corresponding PK8S model provides the same POTS, singlemode duplex, and 20 km configuration.

POTS to Fiber Applications

The PK8S-RM can be used for:

  • PBX-to-remote telephone connections
  • Building-to-building telephone links
  • Long-distance POTS extensions
  • Remote subscriber connections
  • Commercial and industrial facilities
  • Campus communications
  • Fiber-based telephone infrastructure
