12RU Open Line System with continuous 2 x 32 C+L-band ROADM

1FINITY L900 Series


Extreme scale & performance in a sustainable Open Line System platform

The 1FINITY L900 Series is a 1FINITY Ultra Optical System platform. The L900 Open Line System (OLS) features a 2 × 32 continuous C+L-band ROADM-on-a-blade, 16 × 8 continuous C+L-band Multicast Switch (MCS) channel add/drop, and C+L-Band forward and backward Raman amplifiers.

1FINITY L900 key benefits

  • Improves signal strength and quality
  • Reduces cabling complexity with innovative fiber cable architecture
  • Reduces power demand and footprint
  • Expedites installation and troubleshooting
  • Enhances fiber type detection and status monitoring
