The 100G BIDI transceivers are designed for dense applications and provide the ability for operators and service providers to save optical fiber resources. It enables the transmission and reception of 100Gb/s high-speed data over a single optical fiber. Transmission distances cover from 10km, 20km, 40km and 80km. 

10km (BX10): Often uses 1271nm/1331nm 

20km (BX20): Often uses 1291nm/1311nm 

40km (BX40): wavelengths 1305nm/1309nm 

80km (BX80): Coherent optics, multiple wavelengths (e.g., 1273nm-1309nm) for longer reach
