Digital optical fiber unidirectional baseband video/audio transmission device
Transmission of NTSC baseband video from an analog video camera via fiber optic.
This is a fiber optic extender that transmits 1-channel analog video (NTSC) and 2-channel analog audio (L/R) in one direction. There are models that can transmit up to 300m with single-core multimode and standard 25km or a maximum of 60km with single-core single mode. The video can be transmitted at a level of 1.0Vp-p at 75Ω, with a bandwidth of up to 8MHz, allowing for transmission while maintaining high quality that is hard to believe for analog video. Additionally, the frequency range for audio is unusually wide for this type of equipment, supporting between 20Hz and 20kHz. Utilizing this wide bandwidth, there are customers who have successfully extended GPS time pulse signals (10kHz) over fiber optics instead of analog audio. Models are available that transmit only analog video, those that include audio signals, and the 240E series that supports bidirectional data transmission for serial RS-232/RS-422. Furthermore, for cases requiring multi-channel transmission, card-type variations that can be mounted on a chassis are also available.
