400GBASE-LR4 QSFP-DD PAM4 1310nm 10km DOM LC SMF Optical Transceiver Module

The Hyper Photonix HSD1-400-LR-C4S is a high performance, cost effective module for optical data communication applications to 400G and transmission distance up to 10km on SM fiber. The transceiver consists of two sections: The transmitter section incorporates a quad channel EML Laser, a quad channel driver and a DSP. The receiver section consists of a quad channel PIN photodiode integrated with a quad channel transimpedance preamplifier (TIA) and sharing DSP with transmitter. The module is hot pluggable with a 76-pin connector. The high-speed electrical interface is base on low voltage logic, with nominal 100 Ohms differential impedance and AC coupled in the module.
