Optical line systems: the road to 100Tbps
Optical system capacity enhanced by extended C-band, Super C-band, and C+L bands
Advances in transmission, optical line amplification, and ROADM switching technologies are enabling more wavelengths to be transported on optical fiber systems. The additional wavelengths transmitted enables a greater overall transmission per fiber pair improving network economics.
Advances in transmission, optical line amplification, and ROADM switching technologies are enabling more wavelengths to be transported on optical fiber systems. The additional wavelengths transmitted enables a greater overall transmission per fiber pair improving network economics. Today's industry transmission standard is 96 wavelengths in the extended C-band. The industry is currently in the midst of evaluating the merits of "Super C-band" and C+L solutions. The higher wavelength systems pave the way for 100Tbps transmission. Network operators are constantly searching for the lowest cost per solutions. Super C and C+L require technology ecosystem development. Once Super C and C+L achieve high volume production, the communications services providers will be able to reap the benefits of lower cost per bit systems.
