Extend POTS Telephone Service Over Singlemode Fiber

The PK8S POTS-to-fiber converter installation kit provides a practical solution for extending analog telephone communications over singlemode fiber. It allows POTS telephone service to be transported between locations without relying on long copper telephone runs.

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

FXO and FXS POTS Connectivity

The PK8S 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.

Long-Distance Singlemode Fiber Transmission

Singlemode fiber allows the PK8S to support longer-distance POTS communications. The specified distance capability is 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.

Standalone POTS Fiber Installation

The PK8S is designed for standalone installation, making it suitable for applications where a rack-mounted chassis is not required.

For rack-mounted installations, the corresponding PK8S-RM provides the same POTS, singlemode duplex, and 20 km configuration in a rack-mount format.

POTS to Fiber Applications

The PK8S 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
