Brief Introduction to Each Component
In order to ensure full understanding of the DTV platform, we pick up one type from each configuration and explain the properties and functions.

TL510/TL560 Series HD_SDI、3G_SDI Optical Transceiver

TL510/TL560 series HD_SDI, 3G_SDI optical line terminal realizes the interconversion between electronic signals and optical signals of single channel or multiple channels. This optical line terminal is most often used to transfer 2.97Gbps 3G-SDI UHD video signals. Not only that, it's applicable for kinds of SD-SDI SD video signals of 143M, 177M, 270M, 360M and 540Mbps. Wide applications of the device have also been found in the transmission of 16 kinds of signals with a CWDM wavelength range of 1270nm-1610nm (ITU-T G.694.2 compatible)

CV313 Two Way 3G/HD-SDI Optical Transceiver
CircLoop optical transceiver realizes good conversion between HD-SDI/3G-SDI electrical signal and optical signal, well suited for SMPTE 259M (143Mbps - 360 Mbps), SMPTE 344M (540Mbps) SMPTE 292M (1.485Gbps) SMPTE 424M (2.97Gbps) as well as DVB-ASI (270Mbps). It provides 16 kinds of CWDM optical waves with a wavelength range of 1270mm-1610mm.

TL 309 DS3/E3 to ASI Splitter (Up to 4 Channels TS)
Strictly compliant with ANSI T1.120 DS3, ISO/IEC, MPEG-2 and DVB requirements, supporting frame structure of G.804/G.752 (DS3), this splitter is extremely appropriate for MPEG-2/DVB transport stream and single frequency network, which has been extensively applied in such network systems as CMMB, DVB-T and DMB-T. A single module is able to split DS3 signal into 4 groups of 8-channel ASI stream. Each group is equipped with main output interface and subsidiary output interface.

SP108 1 to 4/8 Channels ASI, HD/SD-SDI, 3G-SDI Distributor
SP108 distributor has a modular design and is ideally suitable for DVB-ASI, SMPTE 259M (143Mbps-360Mbps), SMPTE 344M (540Mbps), SMPTE 292M (1.485Gbps) and SMPTE 424M (2.97Gbps). For single modular distributor, it is capable to accomplish the distribution of 8-channel ASI, HD/SD SDI and 3G-SDI signal. One case can hold three pieces of distributors at most, and provide 1 to 8 channels distribution and cascaded transmission of 22-channel signal.

SS100 ASI Signal Switcher (Automatically)
This signal switcher features a number of outstanding advantages and properties, such as 2X1, manual and automatic switch, one channel and multi-channel PID control and transport stream analysis. Not only that, it directly shows the status of transport stream, wrong switch of sync byte, loss, change and wrong switch of PAT, PMT, SDT and CAT, TS cut and more. It can be used in digital satellite receiver and multiplexer or independently used. An open network control protocol enables the switcher to be controlled by net-manager software of other companies or linked with other devices.

TL405 SFN Transmission Adaptor
The single modular adapter transfers 4-channel ASI signal to 4 groups of DS3/E3 signals. Each group has main and subsidiary output interfaces. The built-in 4×4 matrix switcher has the ability to transfer any channel ASI signal to any channel of DS3/E3 signal.

TL401 SFN Adaptor
In transport stream, TL401 SFN adaptor periodically produces and inserts SIP in transport stream and automatically adjusts output code rate in accordance with 33 types of GB20600-2006. By doing this, the signal synchronizes with signals sent by all transmitters in digital terrestrial television system. Plus, ASI to DS3/E3 and ASI to E1×4 are available to support the transport of SFN signal between microwave, SDH and more.

IR601 Transmission Network Adaptor
As for transmission network adaptor, it mainly converts TS signal of IP network into ASI signal. This type of adaptor can also work with IP600, TL300 and TL400 adapters and provides different plans for DTV signal transmission. Generally, the adapter is well suited for multicast, unicast, MPTS (Multi-Program Transport Stream) and SPTS (Single-Program Transport Stream). For single module device, it supports IP input (RJ-45) and dual-channel ASI output.

TL100 Demodulator
The conversion from DVB-C, DVB-T, DVB-S/S2 and GB 20600-2006 signal to ASI signal is completed by TL100 demodulator. The modular demodulator can be inserted with 5 independent modules, which is easy to install and maintain. Plus, this device meets requirements of SNMP.

TL110 Demodulator & Adaptor
TL110 demodulator converts DVB-C, DVB-T and DVB-S/S2 signals into IP signals and is well suited to transfer signals of DVB-C 16, 32, 64, 128 and 256 QAM. It provides automatic test and adjustment, transport stream analysis and MPTS demultiplex. Additionally, this functional device can send each program transport stream to different addresses according to User Datagram Protocol.

CV103 Analog, AES Inter-Converter and Switcher
Complying with AES, IEC60958, S/PDIF and EIAJCP1201 requirements, this converter provides a great guarantee of high quality audio conversion.
