OLT Specification Summary

In the optical communication process, it is the access network with light as the transmission medium, replacing copper wire, used to access each home, optical access network (is our home wifi). Optical access network generally has three parts: optical line terminal OLT, optical network unit ONU, optical distribution network ODN, where OLT and ONU optical access network core components. But the classification of OLT has been somewhat ambiguous, for all the collation, for reference only.

GPON FTTH with 10G

1, mixed GPON and 10G GPON

GPON and 10G GPON share one ODN, but due to different wavelengths, a passive wavelength division multiplexer WDM1r is required.

Advantage: sharing one ODN, save the ODN construction cost

Disadvantage: 10G GPON ONU and GPON ONU are complex, difficult to maintainance.

2, Build a 10G GPON

10G GPON and GPON network are separated physically, clear network structure, which is convenient for management and unified business planning.
