Conclusion

Conclusion u u G-PON’s passive, built-in traffic aggregation, seamless integration into existing fibre plants, huge user capacity, service oriented FCAPS, Advanced Security support, High Availability options such a path protection, and flexible ODN topology such a linear add/drop bus, makes it a perfect match for building Optical Broadband Railway Line (BRL) Access Networks As Railway’s deploy G-PON for the Access and Edge Aggregation portion of their Optical Fibre communication (OFC) networks, it is expected that as of yet un-envisioned Railway-specific new revenue generating services and applications will be realizable due to G-PON’s any-play service architecture. © 2012 27
