MDC interface 100G SR4 optical module adopts QSFP package and supports MDC connector cables. 4 groups of MDC optical interfaces are used for connection, and a total of 8 optical fibers are used for parallel transmission. The MDC connector is a duplex connector designed to provide efficient, high-density fiber optic connections. 

100G QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links over multimode fiber. They are compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4 and CAUI-4. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA. The transceiver is RoHS-6 compliant per Directive 2011/65/EU.
