100G QSFP28 Bidi optical Transceiver enables the transmission and reception of 100Gb/s high-speed data over a single optical fiber. It use one PAM4 to minimize point of failures compared to a 4-lane standard part. We can offer single fiber 100G connectivity for wavelength 1271/1331, transmission distance 10km, 1291/1311 20km, 1304/1309 30~40km.
