400G QSFP-DD ZR 120 km

Ascent’s QSFP-DD-ZR-120 module is intended to be used in conjunction with a host platform to support 400G transmission over optical links in DCI applications. The module can be portioned into four parts: oDSP, optical component IC-TROSA, Controller and Power supply.

    Hot Pluggable QSFP-DD

    Supports 400G PM-16QAM Modulation

    Full C-band wavelength tunable

    Supports 100G/75 GHz channel spacing for 400G PM-16QAM

    Reach beyond 80 km to 120 km for 400G over SMF without inline chromatic dispersion compensation

    Supports C-FEC

    Hardware Specification Compliant to QSFP-DD-Hardware-rev5p0

    Management Interface Compliant to QSFP-DD-CMIS-rev4p0 and oxf2019.015.05-CMIS

    Supports 400GE, compliant with 400GAUI-8 interface, the high-speed lane supports 8x50G configurations

    QSFP-DD class 8 (Maximum power consumption 16.5W)

    Operating case temperature: 0°C to 70°C

    LC connector
