The VMC-R-X-2 is factory set to reclock at 270 Mb/s to accommodate DVB/ASI and will not reclock at 177 Mb/s. When

operating at 177 Mb/s, the receiver may generate bit errors.

Assumes minimum transmitter output power of -12 dBm with minimum extinction rate of 9 dB (VMC-T-X-2) over

9/125µm. Single Mode Fiber (SMF) at 140/177/270/360/540/1485 Mb/s. The minimum link distances are based on worst
case receiver sensitivity (VMC-R-X-2 simplex receiver VMC) with color bar test signal. The minimum link distances will
be reduced with SDI test matrix.
