The OTR-302 is a compact, cost effective fiber optic extender pair capable of extending bi-directional HD-SDI over fiber. Extend signals from 270 Mbps up to 1.485 Gbps up to 100 Km on a single SM fiber. Meets SMPTE SDI standards maintaining error free transmission of SMPTE 292M, 259M and ASI over the entire 100 Km distance. The OTR-302 provides error free transmission with RP-198 pathological patterns. Additonally, there is a loopout of the local input and 2 dupilcate copy outputs of the remote side of the link. The units are built with a stand-alone compact enclosure making it the perfect solution for OB trucks, remote broadcast, mounting by remote security cameras or any other applications that might need a “throw down”, wall mount or shelf mounted fiber link. The OTR-302 has an extended temperature range making it a good solution for mounting in NEMA enclosures.
