DMTx4, 1550 Direct Mod TX

ATX supplies directly modulated C-Band DWDM transmitters to 1.218 GHz at 100 GHz spacing, supporting ITU channels from 20 to 59. These DMT DWDM transmitters are single-slot modules with 2, 3 or 4 wavelengths per module, which can have individual outputs or can be internally multiplexed to 1 output. DMT2 versions have a common broadcast and 2 narrowcast inputs, while DMT3 versions have a common broadcast and 3 narrowcast inputs, and DMT4 versions have 4 unicast inputs. DMT4 versions are especially rack space-efficient achieving the density of 16 transmitters per RU making them ideal for medium reach, high density applications.
