The DLC300 Optical Transmitter/Reciever/Repeater incorporates numerous features in a flexible, easy-to-deploy and configure module with unparalleled quality and reliability. The module optically transports all digital formats from 19.39Mb/s ATSC to 3G-SDI (SMPTE 424M). To minimize inventory costs and simplify deployment, it can be configured as a receiver, transmitter, or repeater. For route diversity and optical flexibility the DLC300 also features dual optical SFP modules available in WDM, CWDM, or DWDM optical wavelengths. To transport across metro optical amplified networks, dithering of all SDI formats has been included, as well as conversion from SMPTE 310M to DVB-ASI.

The DLC300 interoperates with other DigiLink modules and can be used as a repeater for the DLC103, DLC150E, DLC170, DLC274, DV6000, DL1220, and DL2701.  Easily configured and monitored remotely via the DigiLink Manager Element Management System.  Cost-effective, flexible, and reliable, continues Artel’s tradition of making the world’s most innovative and reliable video over optical transport hardware.
