QXP 50G single lambda BiDi Transceiver completes transmit and receive wavelengths self-tuning at initialization phase, no need to distinguish Transceiver types during deployment and maintenance, so the Transceiver is easy to use, without risk of mismatch. By using this kind Transceiver, the asymmetric delay of the optical fiber link is very small, so there is no need to consider the optical fiber delay difference during 5G deployment, which simplifies deployment and reduces management costs.
