The high data rates associated with serial digital links impose their own constraints on the length of cable runs within a facility. Those members of the IQ Modular range that rely on SDI connections have inputs and outputs designed to allow the maximum length of copper cable without signal degradation. However, all copper cabling has its limitations, particularly on large sites, at high data rates or in areas susceptible to electromagnetic interference.
The solution for these most demanding circumstances is fiber optic interfacing. Compared with copper, fiber optic cabling offers secure communications over greatly increased distances with complete immunity from electromagnetic interference and ground loop problems.
The IQ Modular range facilitates the use of fiber optics with single and dual channel options for single mode transmitter and receiver modules. Both are designed for use with serial 4:2:2 signals at 3Gbit/s, 1.5Gbit/s HD and 270 Mbit/s SD data rates, signals are reclocked as standard. The modules are equally suited to both SDI signals and to those encoded in ASI format.
