The unique link to the Ultra High Definition

YOUR AUDIO VIDEO SOLUTIONSLEMO launches the new 1S.275 Series for 12G-SDI, 75 Ohm robust push-pull connectors compliant
with the SMPTE ST 2082-1 standard for signal/data transmission. The 12G-SDI allows a transmission
rate of 12 Gbit/s meeting the 12G-SDI transmission standard and offering eight times the bandwidthof a normal HD-SDI in a single link.
This connector is LEMO’s response to the fast-paced technology evolution and market requirements
towards high transmission rate, lighter structure, low latency demand in live events for the Audio Video
Broadcasting (AVB) market segments as well as other market segments for medical imaging platforms
like endoscopy and laparoscopy amongst others.
This connector is optimized to allow a smooth transmission with high accuracy, reliability, low return
loss, and can replace a dual 6G or Quad 3G links. Today many 4K professional cameras uses Quad link
BNC connectors simultaneously to transmit 12G signals for UHD displays. The new LEMO productwill allow the transmission of 12G-SDI from a compact single link connection for UHD displays.
