HD-SDI 2CH optical transceiver module Fiber media converter extender up to 20km
Overview:
This SDI to Fiber extension set includes an SDI to Fiber Transmitter and Receiver for transmitting multi-rate SDI up to 18 miles (30 Km) over fiber using a single-mode or multi-mode fiber optic cable with ST connectors.
It is a miniature-style extension solution that supports all SDI formats up to 3G including; SMPTE-424M (3G-SDI), SMPTE-292M (HD-SDI), and SMPTE-259M (SD-SDI) protocols.
To prevent signal loss, input signals are equalized and ouputs reclocked to 120 meters for 3G-SDI and 140 meters for HD-SDI.
Features:
1. 8-bit or 10-bit digitally encoded and non-compression video transmission
2. Directly compatible with NTSC, PAL and SECAM CCTV camera systems and support RS-232, RS-422
and RS-482 data protocols
3. Power supply and other parameter state indication, which can monitor the operation condition of system
4. Support no-damage regenerative trunk of video
5. Constant input optical power, and large dynamic range, no electrical or optical adjustments required
6. Special ASIC design
7. Industry-grade of operating temperature from 10 to 75, which is applied to the different working environment
8. Hot-swap function
9. Stand-alone type or card-type installed in 19" 2U or 4U rack-mount chassis
10. Optical interface: FC, ST, SC(optional)
11. Abundant signal interface, such as video, data, audio, telephone, Ethernet, binary input/ output and talk back
