4 Video 8 Audio + Data model description

4 Video 8 Audio + Data over single fiber transmitter and receiver kit. 4 Channels CVBS Composite baseband Videos - NTSC or PAL or SECAM + 8 channel Analog Audios and Return RS485 Serial Data Transmitter and Receiver kit over a single fiber 8 Audios are independent and it can be used as an 8 unbalance or 42 Balance ( + G -) Audios, 8 Mono or 4 Stereo Audios

Description

Analog Baseband Composite CVBS Video, Analog Audio, and RS485 Serial Data. These units are easy to control via data RS485 and are plug and play optical converters for helping to send video & audio longer distances. Sending Video and audio using copper wires for a longer distance than 100 feet is very unpractical. Fiber optic cable, Single-mode or multimode, helps tremendously. There are many cameras or other video devices like VCR, DVD players, Set Top Boxes still using analog Audio/Video interface. Our unit has a video BNC 75 ohm interface, for every video, there is double the amount of audios which can be used as single-ended or differential-balanced. For example, 1 video has 2 audios, 2 videos have 4 audios, essentially you have a video port with left and right audio. In addition, the Transceivers have an RS485 serial Data interface, it allows you to send commands to multiple camera's or other video sources from the headend - receiving location. The kit contains 2 pcs, Transmitter and Receiver, each comes with 12VDC power supply. The transmitter needs to be located by the Video / Audio source like a camera, the receiver needs to be located by the monitor or recording device. Units can be used for timing applications to send CVBS black burst over fiber or sync pulses over fiber.

Question and Answers

Question:

So one more clarification. With the F-1V2A-1D-TxRx.

We will be using this to transmit NTSC Black Reference Video and Analog LTC timecode audio to another location. So I would like to order 2 - TX/RX Sets. Can you please identify to wavelengths for Video and Audio TX on these devices? Meaning, if I have one unit TX and I optically Split the ST Fiber and then have Qty 2 RX Units at the same time. Can you confirm?

Answer:

Yes, you are correct. You can use the Transmitter F-1V2A-1D-Tx with a 1x2 or even a 1x4 optical splitter and connect it to 2 or 4 receivers F-1V2A-1D-RX's.

However, it will only be video forward. You will not be able to use reversed RS485 data. This is because if you send the 1550nm from different receivers, the TX will not be able to recognize the reversed signal.

If you intend to use reversed RS data, it would have to be used in a one-to-one configuration.
