HD-CCTV SYSTEM
Repeater / PoC Repeater
HD-SDI repeater has equalizer function to compensate and recover video signals attenuated. HD-SDI repeater is used for extend the transmis-
sion distance. PoC(Power over Coax) is a repeater which supplies power via coaxial cable. If used PoC repeater, it does not need to supply pow-
er into the repeaters which are connected in the middle of line. According to the cable type, maximum number of PoC repeater is dierent.

(HD-SDI ber optic transmission)
In order to make up for the weakness and to reduce transmission
loss and to extend transmission distance to dozens of Km, b-
er-optic transmitter is in use. The advantages are as follows. instal-
lation is easy due to thin cable, and although HD-SDI video can
be transmitted around 100~300m using normal coaxial cable,
but it can be transmitted up to dozen of Km by ber-optic cable.
Moreover, normal coaxial cable is easy to be aected by EMI, RFI
noise, but ber-optic cable is not aected by these electromag-
netic noises, and if used multiplex transmission, several data can
be transmitted through one ber-optic cable.
HD-SDI signal extension
Maximum HD-SDI transmission distance is almost decided according to the type of coaxial cable as shown in the table below.
If you want to lengthen the distance, you may use higher rating cable which has lower signal attenuation or use HD-SDI re-
peater or adopt ber-optic converter for long distance.
