TC1905
Fiber Optic Telephone & Dry Contact Extender
Features
The TC1905 Phone Extender multiplexes one voice channel and one dry contact channel to remote locations over fiber optic cable. The voice channel is compatible with most analog telephones, PBXs or Key Systems. The dry contact channel is bi-directional.
- Extend Telephone & Dry Contact Links over Fiber
- PBX and Key System Compatible, FXO/FXS Selectable
- Bi-Directional Dry Contact
- Multi-Mode or Single-Mode (1300/1500nm)
- One Fiber Bi-Directional Option
- Built-In Power Redundancy
- Rackmount or Standalone
- Tested and Compatible with:
TC1905 is most often used to extend emergency phone service to remote sites in campus networks that also require a dry contact connection. For example, it can be used to provide voice communications for a push button phone and also pass through a dry contact signal to close a remote relay or activate a camera
Applications
TC1905 could be used to provide voice communications for a push button phone and also pass through a dry contact signal to close a remote relay or activate a camera. Other applications include using the inherent benefits of fiber optics to improve voice quality, eliminates electromagnetic interference (EMI) or maximize security.
