FM VIDEO/AUDIO/DATA LINKS
These Frequency modulated links are most versatile. They can send and receive video and up to two sub-carriers of audio or data, all over one fiber. You can have FM video and any combination of audio or data with single or dual sub-carriers. Choose from RS-232, RS-422, TTL, or even a contact closure. The units are available in MM at 850nm & 1300nm. SM is available at 1300nm using an LED. A laser based SM system is also available at 1300nm or 1550nm.
