The ILC274 utilizes Time Division Multiplexing (TDM) to combine four independent 270Mb/s video signals into one optical channel.

The ILC274M and ILC274D provide a space efficient and cost-effective method of transporting up to four 270Mb/s digital video services over a single optical wavelength. Services can be any combination of 270Mb/s video signals including SDI, SDTI, and DVB-ASI. Optical regeneration or repeating is accomplished using the ILC274D which includes drop and continue capabilities, ILC103A, ILC300, or any other system capable of repeating a 1.485Gb/s signal. Using 1310nm, 1550nm, CWDM, or DWDM Small Form-Factor Pluggable (SFP) optics the ILC274 enables transport of up to 160 270Mb/s circuits over a single fiber.
