Key considerations when moved from copper to fibre(PON)

What kinds of network are you using?

  At the beginning, let’s share a table to show the relationship about “Access technology”, “Coverage diameter” and “Service requirement”.

Access technologies and solution

Access technologies and solution

Why choose PON (Passive Optical Networks) network?

  • PON supports Triple-play service, providing competitive all-service solution.
  • PON supports high-bandwidth transmission to break down the bandwidth bottleneck of the access over twisted pair cables, so as to satisfy the requirements of high-bandwidth services, such as IPTV and live TV broadcasts.
  • PON supports the long-reach (up to 20 km) service coverage to overcome the obstacle of the access technology over twisted pair cables and reduce the network nodes.
  • With complete standards and high technical requirements, PON supports integrated services in a good way.
  • PON is the choice of large carriers in the international market.

Main considerations when moving to a PON network

 One of our customers is still on DSL Technology and now looking move to FTTH PON network. And customer asked such a question: What is the main considerations when moving to a PON network? 

Answer 1:

Coz dsl using copper but pon is using optical fiber so i think “optimize network cost” is the first thing they should think about.

Answer 2:

If you have already GPON layout then convert connection from home pass to home ready and then activate the service, but if you are still using copper network then you must first plan and execute fiber network there.

Answer 3:

As a customer ..I felt big difference when I moved from copper to fibre. For a copper technician it is important to know about fibre and connector cleaning.

Answer 4:

fiber is passive no need to a power( no amplifier),,,,,epon is best in term of cost and user friendly…GPON network support more secure than EPON

Answer 5:

This is questions which always asked by our customers. The key consideration should be performance, bit rate and cost. here list out some consideration for you sir reference.

1. copper wire is unstable. Easy to get disconnection after few years using. And the DSL is not support headend managing Modem. It is not good for central management . GPON can do management for all ONt/modem in one OLT. It can even take control on WLAN SSID setting.

2. Bitrate: DSL—ADSL/VDSL have limitation on uplink and down link of bit rate. The uplink of ADSL is max 512KB. But GPON is equal for uplink and downlink. Bitrate reach into 2.5G. And support uplink into 10G XFP/SFP+

3. Cost— Fiber cable is very cheap(for example, 6 cores SM FOC is usd408/KM). In the whole solution cost comparing, FOC+GPON and DSLAM+ copper, you can find out GPON properly is mostly 40% down of copper solution.

There are mature complete GPON solution with max 128 PON ports sub rack in the market. It is extremely low price and fix for those customer which need upgrade from DSL to GPON in small quantity of users like 100 to 2000 users. welcome to ask for more detail.

Answer 6:

hmmm i think
1. Optical budget (nearest-farthest ONT)
2. Bandwidth budget (total bandwidth at 1 pon port is 2,5 Gbps downstream and 1,25 Upstream)
3. QoS such as assure, fix, or etc
4. migration scenario with the fallback scenario
