(1). Two laser test at 1310 nm/1550 nm. 40% OMI/tone (before combined). Distortion products measured at 40 and 85 MHz.

(2). 5 – 85MHz Version, Optical Input = -10dBm, OMI = 20% (after combined)

5 – 200MHz Version, Optical Input = -7dBm, OMI = 20% (after combined)

(3). Tilt is defined as the delta between 5 – 85MHz for 7820R-085 and 5 – 200MHz for 7820R-200.
