Technical principlesof PON:

Application mode 1 of PON technology: FTTH

Applications: Newly-built high-grade residential, High-grade residential reconstruction, apartment villas

Application Features: FTTH, No cooper outside the house, POP in every user’ home, each user own one ONT port, higher costs than FTTB and FTTN; providing various services and voice service can be realized through the internal IAD.

Business Requirements: VOIP, Broadband service, HDTV, Visual communication etc.

Conclusion: Adopting FTTH solution can fully satisfy the requirements of high bandwidth now and then, but the cost is higher.

Application mode 2 of PON technology：FTTB (PON+LAN)

Applications: Newly-built high-grade residential, High-grade residential reconstruction, apartment villas

Application Features: FTTH, No cooper outside the house, POP in every user’ home, each user own one ONT port, higher costs than FTTB and FTTN; providing various services and voice service can be realized through the internal IAD.

Business Requirements: VOIP, Broadband service, HDTV, Visual communication etc.

Conclusion: Adopting FTTH solution can fully satisfy the requirements of high bandwidth now and then, but the cost is higher.

Application mode 2 of PON technology：FTTB (PON+LAN)

Applications: Restruction of old campus (Speeding up the broadband), online service of broadband in countryside (POP down); fiber and copper to the home

Application Features: FTTN or FTTB, Keeping the existing copper for broadband service and voice service, and POP all in the building, cooper distance within 300~1000m, multi-user sharing ONT unit, Lower networking cost than FTTH, but higher than FTTB+LAN.

Business Requirements: VOIP, Broadband service, HDTV, Visual communication etc.

Conclusion: Making full use of the existing network source ,small adjustment for the networking ,flexibly meet the needs of old town ‘s restruction, saving fiber core and uplink data, satisfying the needs of integrated service at this stage and helping for further fiber expanding, lower costs than traditional reformation model of cables.
