E-tone’s single mode dual window coupler can be operated at both 1310nm and 1550nm wavelength level. E-tone applies advanced FBT technology which induces no additional water peak attenuation at 1383nm which displayed by traditional FBT technology; this advantage lead E-tone’s coupler available across the Extended Band (1360nm~1460nm) and insensitive to the operating wavelength from 1270nm to 1600nm
