| I have no idea how fast BPON is; however, another related GPON thread has some rather surprising factoids and infobits:
1. GPON is actually *less* equipment-intensive than BPON at the CO/wirecenter level.
2. GPON results in lower electric bills than BPON.
3. GPON has longer range than BPON.
4. The largest planned GPON installation/upgrade in the world is.....in the US (specifically, the VZ FIOS Network, which will be all-GPON).
And when I mean lower electric bills, I mean at the CO/wirecenter level. The thread discusses a 16,000-subscriber wirecenter/CO (such an example exists: Indian Head, MD is a CO/wirecenter of exactly this size). A typical CO uses 67 kW of electricity on a monthly basis to service those 16,000 subs with a point-to-point (typical copper, BPON or EPON) network. GPON requires only 4.8 kW to service the same number of customers; even scarier, it services the same number of customers while requiring a mere *one percent* of the rack space (one square meter vs. one hundred square meters). The larger the CO, the greater the savings. |

Fiber Optic outside plant has tremendous capacity. It is the electro-optical equipment at both ends that dictate speed. 10Gig optical Ethernet is readily available and 100Gig is in the works. While PON is very different then Ethernet the critical components are the optical/electro converters needed to convert optical signals to electrical and vice versa. Prices on these components is rapidly falling.
Wavelength division multiplexing (WDM) allows many "colors" to share a single single fiber. The combination of very fast channels and ability to carry many colors over a single fiber means for all practical purposes fiber bandwidth is unlimited.
The future looks bright.

2 edits | To all those who can get FIOS or who will be getting it soon. Damn am I jealous !!
I live in broadband no mans land otherwise known as Maine.
We won't be seeing FTTP here for quite sometime if at all unless a third party telco offers it. We are a VZ territory but not for much longer. I laugh and cry at the thought of fairpoint NE buying VZ out.
As for WDM I used to work for LVLT (Level 3) in cambridge Mass and we were doing some amazing things with the technology and this was 7 years ago. WDM over an OC768 circuit was incredible. |
