These products feature four channels of 25G NRZ electrical signals and four channels of 25G NRZ optical signals, a duplex LC connector, a distance of up to 10km reach via single-mode fiber, a case temperature range of 0°C~70°C, and compliance with IEEE 802. 3ba, and QSFP28 . If the module needs to reach the nominal data, the board FEC function must be enabled. The BER 5x10E - 5 is the data that is not enabled by FEC, so that 1x10E - 12 can be reached after FEC. The optical power calculation is based on the OMA value. Powered by Bosa Themes28G NRZ, 56G PAM-4, 112G PAM-4, up to 100, 200 or 400 Gbps aggregate. Offer low insertion loss and cross talk plus excellent electromagnetic interference (EMI) containment. Pervasive bandwidth requirements due to the tremendous growth in wireless devices are the catalyst for large-scale (200 Gbps). The 200G QSFP56 optical transceiver adopts PAM4 (Four-Level Pulse Amplitude Modulation), which transmits two bits per symbol using four distinct voltage levels—effectively doubling spectral efficiency compared to traditional NRZ. This higher bandwidth density allows QSFP56 module to achieve 200G. <0. 9dB,the OMA(min) mo e been listed at www. Please e-mail us at sales@etul.
