Extend POTS Telephone Service Over Multimode Fiber

The PK4M-RM POTS-to-fiber converter installation kit provides a practical solution for extending analog telephone communications over multimode fiber. The system converts the POTS connection for transmission over fiber between locations, allowing telephone service to be extended beyond the limitations of copper cabling.

The PK4M-RM uses multimode duplex fiber with a distance capability of up to 2 km when the appropriate length of fiber optic cable is used.

FXO and FXS POTS Connectivity

The PK4M-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: Multimode
  • Fiber configuration: Duplex

The selector guide lists one FXO and one FXS interface for the PK4M-RM.

Multimode Fiber Transmission

Multimode fiber provides a practical solution for shorter-distance POTS fiber connections. The PK4M-RM is specified for up to 2 km of multimode duplex fiber transmission when the appropriate fiber cable length is used.

All units in the VERSITRON 4-channel POTS converter family use LC optical connectors.

Rack-Mount POTS Fiber Installation

The PK4M-RM is designed specifically for rack-mount installation. The VERSITRON selector guide notes that rack-mount kits include one 2-slot chassis and one standalone enclosure, providing flexibility for centralized POTS-to-fiber installations.

POTS to Fiber Applications

The PK4M-RM can be used for:

  • PBX-to-remote telephone connections
  • Building-to-building telephone links
  • POTS extensions over fiber
  • Centralized telephone equipment installations
  • Remote subscriber connections
  • Commercial and industrial facilities
  • Fiber-based telephone infrastructure
