200G QSFP56 LR4 10km

The Arkoptics 200G LR4 QSFP56 Optical Transceiver Module is designed for use in 200 Gigabit Ethernet links over SMF28 single-mode fiber. It is compliant with the QSFP MSA, IEEE802.3bs, 200GBASE-LR4 and uses 4-level pulse amplitude modulation(PAM4) operating at four wavelengths on a Local Area Network. The bit rate per lane is 53.125Gb/s, which produces an aggregate data rate of 212.5Gb/s by means WDM to the transmit port of the LC connector. The received optical lanes are de-multiplexed from the receive LC connector port to 4 PIN-PDs with low- power transimpedance amplifiers (TIAs) to recover the PAM4 for interfacing with the electrical interface. The electrical interface is in compliance with 200GAUI-4 and specifies the use of four differential electrical lanes operating at 26.5625GBd PAM4 per lane. The bit rate per lane is 53.125Gb/s, resulting in an aggregate data rate of 212.5Gb/s that matches the optical line interface. Digital diagnostics functions are available via the I2C interface as specified by ACMIS4.0. The transceiver is RoHS 2.0 compliant and lead-free per Directive 2011/65/EU.
