*The HD8² takes advantage of the US Conec MDC connectors which is a two fiber connector manufactured with proven 1.25mm ferrule technology used in industry standard LC connectors. Two port MDC adapters fit directly into standard panel openings for duplex LC adapters, increasing fiber density by a factor of two. Supporting port breakout architectures for emerging transceiver MSAs, the smaller size will allow a single array transceiver to accept multiple MDC patch cables, which are individually accessible directly at the transceiver interface. The new format will support four individual MDC cables in a QSFP footprint and two individual MDC cables in an SFP footprint.
