Accelight ’s AQP100CDxxxx020 series single mode transceivers are designed for multiple channel 100GbE transmissions for up to 25km distance over standard G.652 single mode optical fibers (SMF). The transmitter side converts the multi-lane host electrical signals to a single-lane PAM4 optical signal. The module’s optical interface utilizes a single wavelength in the O-band with wavelengths aligned to the LAN-WDM grid with 200GHz channel spacing. The module is Laser Class 1 compliant according to International Safety Standard IEC-60825. The receiver section uses a wideband APD detector and is WDM channel independent. Digital diagnostics functions are available via the I2C interface as specified by QSFP28 MSA specification SFF-8636.
