Who Makes What: GPON Equipment

After years of hype, GPON rollouts are finally starting to happen. Heavy Reading forecasts that by the year 2012, 90 million homes will have a fiber-to-the-home (FTTH) connections, with GPON making up a bulk of those deployments.

To commemorate this joyous occasion, Light Reading has put out a report cataloging the components of a GPON network and the vendors that make them. (See Who Makes What: GPON Equipment.)

Many of these vendors have been in the GPON space for a while, but with big carriers finally rolling out the technology, more vendors around the globe are jockeying to get a piece of the action.

The report examines optical network terminals (ONTs), optical line terminals (OLTs), triplexers, and chip sets. It also examines PON's future, in the forms of 10 Gbit/s GPON and WDM-PON.

In the construction of this report, we may have missed some vendors along the way. If any companies need to be added or any information corrected, please bring it to our attention either on the message board below or by shooting an email to [email protected], placing "Who Makes What: GPON" in the subject line.

re: Who Makes What: GPON Equipment Why not make a "Who Makes What: WDM-PON Equipment"?

The buzz of the summer seems to indicate that WDM-PON is coming and G-PON is obsolete.

re: Who Makes What: GPON Equipment Or so it would seem. Novera, recently picked up by the LG-NT jv, supposedly has between 100k and 200k users currently being fed via WDM-PON, although I've yet to see a breakdown on how those endpoints are actually being provisioned. I.e., the percentage of users that are actually receiving their own wavelengths vs. those who are supported by local field- and in-building- nodes via xDSL and/or IEEE-LAN.

I agree that WDM-PON is quite topical lately, as evidenced elsewhere today by Lightwave's special edition newsletter:

re: Who Makes What: GPON Equipment
You guys do know the Novera system is less bandwidth than a GPON right?

re: Who Makes What: GPON Equipment
Until you actually find out where the components for WDM-PON are. It is sorta like saying that 40GigE is obsolete due to 100GigE TODAY.

16 Wavelenghts at 100Mb/s each....

pretty simple.

re: Who Makes What: GPON Equipment You need to be more specific, and at the same time more inclusive/comprehensive in defining the specifics, if you wish to draw comparisons between GPON and WDM-PON.

I believe you're referring to GPON's UPPER-tier version, which has an aggregate rate of 2.5 Gbps presently, usually "asymmetrical", but can accommodate symmetrical configurationst as well. In practice GPONs are divided among 16, more likely 32, or more end points.

Are you comparing the latter GPON to Novera's LOWER-tiered Speedlight product, Speedlight?

Speedlight's aggregate is rated at 2 Gbps "symmetrical", which is distributed over 16 channels, each rated at up to 125 Mbps (i.e., to each end point).

The next step up Novera's product chain, however, i.e., Novera's UPPER-tier if you wish to compare apples to apples, is the TurboLight product, which has an aggregate rating of 20 Gbps "symmetrical" distributed over sixteen (16) channels, where each channel (end point) is capable of supporting up to 1.25 Gbps "symmetrically", if my cursory read of the pages referenced below is correct:

re: Who Makes What: GPON Equipment Hopefully Light Reading will focus next on xEPON suppliers, with a special slant on its looming use in the enterprise. Were it not for the oversized, bloated designs of ONT/ONU wares today, which traditionally have been geared towards residential triple plays, GE-PON would already be in use in a wide range of business applications today. Indeed, even GPONs are now being deployed for SMBs by some of the MSOs, of all people ...

re: Who Makes What: GPON Equipment In the GPON foodchain no one is making money taking into account huge effort in development. Operators are not happy due to operational nightmare ( as an example if on ONT fails in upstream all the others users fails in upstream). WDM PON is the solution as PIC photonic integrated circuits will allow to reduce the cost of multiple transmitters and receivers to a level not so different from a single GPON transmitter.

re: Who Makes What: GPON Equipment Frank,

Can you elaborate on the comment on "oversized, bloated designs" of ONT ?? what part is unnecessary, eg., triplexer is not needed etc., ??

ramesh.
