SDI & Data over Fiber Optic is
an ideal and economic solution for broadcasting or surveillance applications.
It receives one HD-SDI electrical input, perfectly converts electrical SDI
signal to single mode optic SDI signal. It supports transmission image of
SDTV (143-540Mbps), HDTV (1.485Gbps) and HDTV (3Gbps, 1080p60).
Both transmitter and receiver provide equalizing and
reclocking at input unit in order to re-construct the signal for consistent
quality. Besides, with advanced fiber technology, VSDI can easily pass
pathological pattern to prove its complete transmission.
Hd-sdi optical transceiver, dedicated security
HD SDI monitor, high-definition conference system, support 1080 p (25 hz, 30
hz,50hz,60hz) / 1080 I / 720P with reverse control data. hd SDI optical transceiver product customer
development use for radio, film and television industry, the earliest
application in the television studio, the universiade on live radio, and
later extended to SDI hd monitoring field.

SDI optical transceiver is hd SDI
necessary transmission equipment of the monitoring system, how to identify
the SMPTE standard SDI optical transceiver also confused with so many users,
it can through SDI pathological code test to verify. Transfer characteristic
difference of hd-sdi optical transceiver reluctantly when transmission rate
signal specifications are available, but when the problem of irregular rate
signal transmission immediately reflected, under 1.5 G rate (720 p or 1080 I
used) lower, problems of probability under 3 G rate (1080) p application
problems of probability is high, main performance for high definition video
transmission sometimes appear in the process of the splash screen, black
screen, blue screen, images cannot guarantee continuous smooth playback, the
cause of these problems basically has two: first, adopt hd-sdi optical
transceiver scheme not mature or design defects, this reason minority;
Second, cost factors, on the market most of the hd-sdi optical transceiver
using common SFP optical module, which USES the rate of 1.25 G and 1.25 G
rate digital SFP optical module instead of hd-sdi special VIDIO optical
transceiver SFP optical modules, so inevitable when transmission rate of
irregular large error. Hd-sdi application field of optical transceiver have
higher picture quality requirements, natural intolerable, the picture is not
smooth, so should adopt hd-sdi special VIDIO optical transceiver SFP optical
module, to ensure that high-definition image transmission in the process without
the splash screen, black screen, the phenomenon such as blue screen.
