DigiLink DLC150E

DigiLink SDI/SDTI 4 Channel Analog/Digital AES Audio Embed and Optical Transmitter
DigiLink SDI/SDTI 4 Channel Analog/Digital AES Audio Embed and Optical Transmitter

Product Details

The DLC150E is a flexible audio embedder and video transport card designed for use in the DigiLink video transport system. The DLC150E will embed analog or AES audio into SDI and SDTI as well as transport all standard 270Mb/s digital formats.

The DLC150 functions as both an audio embedder for four channel analog or two stereo pairs AES-3 audio, and as a 270Mb/s video over fiber optics transport module. The DLC150 uses industry standard 1310nm, 1550nm, and CWDM Small Form-Factor Pluggable (SFP) optics. Provisioning and monitoring is accomplished using switches, LEDs, front monitor jack, SNMP or HTTP via DL-Manager.
