Application of photonics integration approach is about to take off

Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. This technology is getting popular a few years ago, however, based on research from LC (LightCounting), the market demanding for SiPh will increase in the next couple […]

Parametric Introduction for Optical Modules

The follow parameter introduction is focused on the performance of internal components packaged inside the transceiver, mainly the transmitter optical subassembly (TOSA) and the receiver optical subassembly (ROSA). Once a client’s line arrives at the TOSA, the signal is converted from electrical to optical. Then, the TOSA sends and transmits the information. In the opposite […]

Takeaways and Conclusion for PON Network

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 […]
