How Does Fiber Optic Modem Work?
Fiber optic modems receive incoming optical signals over fiber optic cables and convert them back to their original electronic form for full duplex transmission. Together with the tactical fiber optic cables, the FOM provides a rugged, secure, and easy deployable optical link. What is the maximum distance that a fiber optic modem can go?
The maximum distance of a modem can go is the difference between receiver sensitivity and transmit power of the fiber optic modem, divided by the transmission loss of the fiber used. For example, a basic single-mode OSD815 digital video system's transmitter power is greater than -10dBm and its receiver sensitivity is better than -29dBm so the difference of 19dB at 1310nm allows operation over at least 45km. Note this would be very poor design because there is no allowance for a link margin.
