OTX 1712

Analog Sync / Video Fiber Optic Transmitter

 Supports analog black burst, bi-level, tri-level

sync signals and NTSC and PAL composite video

 Passive loop output

 Broadcast quality performance

 Error free optical transmission

 Versions for LC, ST or SC ﬁber connections

 Multimode version available

 Up to 10km (6.2 miles) singlemode

 Up to 300m (984 feet) multimode

 Supports hot swapping and hot plugging

Using the same basic module we provide four versions suitable for LC, ST

or SC singlemode ﬁber connections, as well as a version for multimode

ﬁber. Each version has a different SFP installed.

The OTX 1712 is a compact analog sync or NTSC/PAL composite

video to ﬁber optic transmitter. This device is speciﬁcally designed

to combat the restrictions involved with the distribution of

broadcast quality analog reference and composite video signals

over long distances.

When paired with the ﬁber optic receiver ORX 1702 you have a

very cost effective optical transmission system for analog sync

reference signals or NTSC/PAL composite video. This device is

particularly useful for reference sync distribution between remote

installations to maintain correct synchronization.

Unlike other very basic analog to ﬁber conversion solutions, the

OTX 1812 incorporates technology to maintain a very high degree

of sync and burst phase stability during the conversion and ﬁber

transmission.

The module converts the NTSC/PAL video signal to an SDI signal

(including reference and other relevant information) before it is

converted to ﬁber. Therefore when the OTX 1712 is used for NTSC

or PAL video sources it is possible to convert the ﬁber signal

directly to SDI if required using an SDI receiver (e.g. ORX 1802).

The OTX 1872 provides a passive loop output and support for LC,

ST or SC singlemode ﬁber connections. An LC version suitable for

multimode ﬁber is also available.
