Mini 3G SDI Video-to-Optical Transceiver
Optical Transport Equipment
Fiberwdm
Power Supply - Power Consumption: 2W(max.) Power Supply - Power Supply Voltage: DC5-24V Input Light Center Wavelength: 1310nm
HD multimedia surveillance often requires long-distance uncompressed digital audio/video transmission. Ordinary cables suffer poor output, interference and limited reach. The 3G/HD-SDI-T/R optical pair carries 3G/HD-SDI over 1m–20km, addressing these problems. Low attenuation, broad bandwidth, interference resistance, security, compactness and light weight suit long distances/special environments while reducing construction cost and wiring complexity without sacrificing quality. 3G/HD-SDI-T is the transmitter and 3G/HD-SDI-R the receiver. The source also labels the transmitter 3G/HD-SDII-T. Together they send video over fiber without compression and faithfully reproduce the original signal.
