ADTEK Debuts the First 100G SR4 Optical Transceiver with MDC Interface
Responding to the growing demands for high density cable with duplex assemblies accessibility, ADTEK Technology developed the world’s first 100G SR4 QSFP Optical Transceiver with a MDC Interface and introduced the new product at OFC2022.
The ADTEK 100G SR4 QSFP optical transceiver contains an MDC receptacle able to accept 4 MDC duplex assembliess. The quad receptacle design offers the ability to breakout the 100G transmission into four 25G transmission paths over 4 MDC cable assemblies without the need of a breakout cable or module. The 0.15 dB insertion loss of the MDC assemblies’s ceramic ferrules is lower than the typical insertion loss(0.35dB) of MT ferrules providing more insertion loss headroom for your communications path.
The ELiMENT™ MDC Assemblies by US CONEC is a Very Small Form Factor (VSFF) duplex fiber optic assemblies designed for high density duplex connectivity. The MDC assemblies triples the density of traditional duplex LC assemblies systems providing up to 432 fibers in 1 RU and offers the simplest polarity reversal method of any duplex assemblies.
