re: Hitachi GPON Gets RUS ApprovalFirst of all, the leading sentence under this article's title on the main LR page is misleading and therefore incorrect:
"The AMN1220 becomes the first GPON unit to receive USDA Rural Utilities Service acceptance..."
Per LR's own site, Optical Solutions FiberPath 500 GPON product was awarded such status in 2003:
There may be other GPON equipment types that are RUS approved as well, but in any case the omission of "full-rate" creates a misleading tease for the article.
That said, RUS listing will be very helpful for any vendor seeking to sell to 3rd tier carriers. The 3rd tier carriers tend to pay more, tend to demand less, and (some of them) are more technically daring than the RBOCs. Many of them won't upgrade without an RUS loan.
Example from http://freenet.msp.mn.us/peopl... "Without RUS support, East Otter Tail says it would be unlikely to proceed with further implementation of the FTTH network."
3rd tier carriers therefore make an important lab for proving in equipment before exposing it to the greater challenges of 2nd and 1st tier networks. They can also be more profitable on a unit basis owing to their limited negotiating leverage.
re: Hitachi GPON Gets RUS ApprovalAccording to the article
"Those loans have helped spread broadband access to more than 500,000 households in 1,000 communities throughout the country that would have otherwise not have advanced telecom services available to them, according to USDA data."
And the experts reporting for and reading an industry trade site like LR don't bat an eye.
RUS needs to raise the bar. So do the rest of us. Claiming advanced telecom services, using the FCC's defintion of broadband, at $2400 per household is NOT something to be proud of. Maybe we can take somes lessons from previous generations who actually advanced our society.
"Here is an opportunity to do a big, basic work, such as comes to few in the course of a lifetime. The individual who fails to vision the importance of the task has no moral right to hold a position of authority in its performance." - Thomas H. MacDonald, Chief, Bureau of Public Roads, December 1921
"I think by far the most important bill in our whole code, is that for the diffusion of knowledge among the people. No other sure foundation can be devised for the preservation of freedom and happiness.
...Preach, my dear Sir, a crusade against ignorance; establish and improve the law for educating the common people." -Thomas Jefferson August 1786
A universal broadband platform will be anchored by knowledge diffusion. The diffusion won't be bounded by time or place. It's our chance to do something of real value. Doing so requires taking some risk (and maybe even a loan default or two.)
re: Hitachi GPON Gets RUS Approval Yes there were standards in place in 2003. Like all standards, GPON has been extended, clarified and updated since 2003.
re: Hitachi GPON Gets RUS ApprovalI'm not that familiar with the OS GPON product. But in 2003 the possibility of it being EPON is very high. The Hitachi product is true GPON not EPON called GPON. Some early PON vendors called EPON GPON. I would not call the 1220 GPON EPON, they are 2 totally different beasts. Hitachi uses true GEM to achieve 2.4down/1.2up. I question if other GPON vendors are truly using GEM as some of the docs I have read point to fixed cells which points to a BPON based transport within the PON.
re: Hitachi GPON Gets RUS Approval To your question about the ATM portion of GPON. There is, in the standard but becoming obsolete, an ATM partition of the GPON Frame. Nobody has implemented it, as it would be simpler just to do BPON at that point.
re: Hitachi GPON Gets RUS Approval If you want your product to be purchased with RUS funds, you need RUS approval.
GPON initially had a range of speeds (in fact they are still in the standard). The 2.4/1.2 variant came out of the JPC as the primary variant. Motorola was pushing a 1.2/1.2 GPON (not EPON but GEM framed). OSI never did EPON.
They were the first to call their products GPON. But there wasn't a standard definition of GPON back then, was there?

I'll adjust the article.
