The Fiberlink 3380 Series allows you to transmit 3G, HD or SD-SDI as per SMPTE 424M-2006, 292 and 259 with the ability to embed up to 4 channels (2 pairs) of analog line level audio. Convenient switches on the 3380 Series transmitter allow the operator to embed each of the two pairs of audio independently, to strip previously serialized audio, or to pass it through without modification. At the receive end of the fiber optic link, the operator can decide which audio pairs they need de-embedded. Audio signals are not required to operate the Fiberlink 3380 link and it can be used as a stand-alone 3G/HD/SD-SDI optical link. Previously serialized data is left intact throughout the entire transmission process and the 3380 Series is immune to pathological signals over the entire budget link and operating temperature range. Signals are equalized and re-clocked prior to fiber optic transmission and the 3381 receiver features a re-clocked SDI output.
