Detailed Product Description

ASI/SDI Optical Transmitter/Receiver DMB-7018/7118 are the pair optical transceiver based on optical fiber. The ASI/SDI signals is converted to optical signals at the transmitter end and converted back to electrical signals again at the receiver end. It can achieve ASI/SDI signals long distance transmission instead of SDH. The transmission distance can be up to 100Km. They are suitable for News collection, signals transmission between the headend and the transmitter, etc.

Main Features

• Transmit 1 ASI /SDI signal over one optical fiber
• The DVB ASI input/output comply to EN50083-9 connector
• Auto adapt to 143, 177, 270, 360, 540Mbps SDI inputs
• DMB-7018 optical transmitter contain clock recover module, which can compensate the cable transmission loss
• Support 4 ASI outputs (optional)
• Transmission distance up to 100 Km
