The DLC274M and DLC274D utilize time division multiplexing (TDM) to combine four independent 270Mb/s video signals into one optical channel. This enables transport of up to 160 270Mb/s service over a single fiber making it ideal for conserving both fiber and rack space. Services can be any combination of 270Mb/s video signals including SDI, SDTI, and DVB-ASI. Optical regeneration or repeating is accomplished using the DLC274D which includes drop and continue capabilities, DLC103, DLC300, or any other system capable or repeating a 1.485Gb/s signal. Using industry standard 1310nm, 1550nm, CWDM, or DWDM small form-factor pluggable (SFP) optics the DLC274 enables transport of up to 160 270Mb/s circuits over a single fiber. The DLC274M and DLC274D modules for the DigiLink chassis are easily monitored and managed remotely via DigiLink’s DL-manager element management system.
