The IN-Q3JZ1-TC is a pluggable Digital Coherent Optics (DCO) transceiver. This DCO can be plugged into compatible switches and routers for coherent transmission of 400GbE signals over DWDM links up to 120 km. The transmitter is tunable over the ITU C-Band (75 GHz grid). The INQ3JZ1-TC includes a narrow linewidth tunable laser, Silicon Photonics Modulator ICR, and a DSP. Optical signals are transmitted and received from the module by standard duplex SMF and LC receptacles. The client/electrical interface is compatible with IEEE P802.3bs 8-lane 56G PAM-4, as used for “gray” datacenter optical transceivers, for example 400GBASE-DR4. COLORZ 400 (ZR) modules are mechanically and electrically compatible with the QSFP-DD MSA and utilize a 76-Pad electrical connector. The IN-Q3JZ1-TC utilizes 7 nm coherent DSP technology, including its low power C-FEC as well as innovative silicon photonics, driver, and TIA technology to provide coherent transmission performance previously only available on lower density, higher power, and higher cost systems.
