Optical link budgets – Vary by ODN class and PON type. However, 29 dB is often used as a “loose” loss budget for both XGS-PON and NG-PON2 for Class N1/N2 applications. This reasonably healthy link budget can be adversely affected by bending losses at NG- PON downstream lambdas. Spectral losses – XGS-PON (1270 nm) upstream […]
