W&T 41215 Universal FO-Interface 20mA

Model: 41215

$438.00

Reliably transmit TTY over very long distances

The model 41215 Interface features a selectable active or passive 20mA interface which the converter changes into a universal optical interface for single-mode and multi-mode glass fiber optics.

 

Interfaces:

  • 1x 20mA
    • 9-pin Sub-D plug
    • Selectable active or passive mode
    • Alternate designations: Current loop, TTY, line current interface
  • 1 x single-mode / multi-mode glass fiber optics
    • SC connector

Management and connectivity:

  • No re-configuration of transmission parameters required
  • Universal 20mA interface for singlemode and multimode glass fiber optics
  • Active/Passive mode can be set individually for both loops
  • Noise-immune transmission over a distance of up to 20 km
  • Galvanic isolation up to nearly any value between the connected devices

Voltage supply:

  • External
    • 12V-48V DC via plug-in screw terminal
    • Galvanically isolated power connection

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

Data transmission over long distances and in extremely noisy environments make the use of fiber optics the logical choice as a physical transmission medium.

The use of plastic fiber optics allows easy-to-install connections over relative short distances of up to 100 meters. But for distances above this limit the use of glass fiber optic cable is unavoidable.

While distances of up to 4km are easily accomplished with multimode fiber optics, greater distances are the domain of singlemode fiber optics.

It used to be that routing and assembling glass fiber optics created significant problems for the users, but today - thanks to the wider use of glass fiber technology in networking - many companies are offering this work as a service.
