Metrodata's Fiber Optic Modems  (FOM) provide our Defense users with efficient electrical to optical conversion. Typically military electronic comms and data signals are provided on serial interfaces on Encryption Equipment, Radio Relay Systems and Satcom Equipment. The line driving distance of most serial interfaces is not very far and in the past lots of repeaters were necessary to get any decent distance. With the increased use of fiber, its easier to get decent distances, even up to 100 kilometres. 

With Metrodata, we specialise in high throughput serial interfaces, and supporting transport of Telecom rates over our Fiber Optic Modems. 

Metrodata FOM's are available in the following Optical interfaces:

• Single Mode Short Haul SC
• Single Mode Long Haul SC
• Multi Mode SC
  

Metrodata FOM's support Serial side and Telco/G.703 including:

• E1,
