Functional Block Diagram
General Description
FQDD-400G-DR4 is a Silicon Photonics 400G (4x100G) DR4 transceiver. FQDD-400G-DR4
is a fully integrated, 425 Gb/s optical transceiver for SMF links up to 500m. FQDD-400G-DR4
transmits data in compliance with the optical interface specification IEEE
Std802.3-2018 Section 8 400GBASE-DR4. 400GBASE-DR4 specifies the use of 4-level
pulse amplitude modulation (PAM4) at 53.125 Gbaud operating at four parallel channels
with wavelength on the range of 1304.5-1317.5nm. The bit rate per lane is106.25
Gb/s, which produces an aggregate data rate of 425 Gb/s by means PSM to the
transmit ports of the MPO-12 connector. The received optical lanes are paralleled
from the receive MPO-12 connector ports to PIN-PD built in PIC (Photonic
Integrated Circuit) to recover the PAM4 for interfacing with the electrical
interface via with transimpedance amplifier (TIA) surfaced-mounted to PIC.
