Solutions of PON


What is a Gigabit Passive Optical Network (GPON)?

A Passive Optical Network (PON) is fibre-optic telecommunications technology that only uses fibre and passive components like splitters and combiners rather than active components like amplifiers, repeaters, or shaping circuits, to deliver broadband network access to end-customers. Passive optical networks cost significantly less than those using active components.

A gigabit passive optical network (GPON) are currently the leading form of passive optical networks.

A gigabit passive optical network is a point-to-multipoint access network and uses passive splitters in the fibre distribution network, enabling one single fibre connection to serve multiple end users.

It achieves this with a passive optical splitter in a junction box, usually in the pavement/road manhole.

Once it reaches the development or estate, where a cluster of end customers reside, a splitter is connected.

From here, multiple fibre cables fan-out of the splitter connecting to homes via an Optical Network Unit (ONU).

Encryption is used to keep each user’s data secured and private from other users.

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.
