200G QSFP56 FR4 2km

The Arkoptics 200G FR4 QSFP56 Transceiver Module is designed for 200GBASE Ethernet throughput up to 2km optical communication over single-mode fiber (SMF). The module converts 4 inputs channels of 50Gb/s PAM4 electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 200Gb/s PAM4 optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s PAM4 input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 133nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module. Host FEC is required to support up to 2km fiber transmission.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP56 Multi-Source Agreement (MSA). The transceiver is RoHS compliant and lead-free per Directive 2011/65/EU. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
