Product Introduction

 

The ASI/SDI optical terminal equipment carries on the TS symbol stream directly through the ASI connection after the optical fiber the high grade transmission. The interior through the wavelength division multiplying may two-way transmission 270M standard MPEG-2/DVB the ASI symbol stream. It may serve as arranges the decoding system's baseband transmission platform, compares with the SDH transmission facility, it may save the funds and do not need the adapter. At present, this product has formed the scale production.

 

 

 Feature and application

 

 Features:

● It achieves multi-channel programs stream transmission.
● Digital transmission can meet the demand for high quality image transmission.
● It could be up to radio transmission quality.
● Complete real-time transmission, no delay.
● The high anti-interference capacity could work in the bad environment.

 

● The short distance program transmission between the television stations or between the television station and the engine room.
● Each profession supervisory system or video conference system for ASI signal fiber optic transmission.
