2. 2. Lightwave - Industry mulls over WDM-PON technology

   However, it,s simply cost prohibitive to locate a laser at every residence, admits Randy Eisenach, market development manager for Fujitsu Network Communications, Access Division (http://us.fujitsu.com/telecom). ,You just can,t have an ONT [optical network terminal] at the side of the house that costs multi-thousands of dollars when service providers are looking at $100 to $300 solutions,, he says.
   ...
   Fujitsu claims it is developing an ONT that will operate at any wavelength- without a laser. ,What it does is receives the transmitted wavelength, re-modulates it, amplifies it, and sends it back toward the OLT,, Eisenach explains.The vendor is examining numerous technologies to help lower the cost of the colorless ONT, including silicon optical amplifiers (SOAs).Because the signal must be amplified, some kind of amplifier is required, and Fujitsu thinks its SOA-based on quantum dot technology-is the right answer. ,It will get us to the silicon optical amplifier at a very low cost point,, says Eisenach, ,and we can do it uncooled.,
   
   Eisenach does not expect WDM-PON technology to be economically viable until the 2010/2011 timeframe.WDM-PON will never meet the price points of BPON or GPON, he says, but over time, ,that gap shrinks tremendously.,
   
   In the meantime, Fujitsu has developed an interim technology that marries GPON with CWDM to enable eight times more capacity in the downstream direction-at a fraction of the cost of WDM-PON. ,This is, to us, a more realistic, cost-effective, and efficient near-term solution to do multiple-wavelength PON,, Eisenach asserts.
   
   The FLASHWAVE 6100 GPON platform, which includes the OLT and ONT, supports what Fujitsu calls a hybrid GPON architecture, delivering higher capacity than the standard GPON technology.All the optics on the OLT end of the FLASHWAVE 6100 are based on small-form-factor pluggable (SFP) transceivers, which can be replaced with CWDM SFPs.The PON splitter is then replaced with a simple splitter and CWDM coupler at the service area interface. ,The combination of the passive splitter and CWDM coupler allow you to break out those wavelengths and reinsert them across any number of homes or businesses,, explains Eisenach.All of the ONTs remain the same, allowing carriers to achieve eight times their current capacity at a minimal cost compared with WDM-PON.
   
   For his part, Eisenach is not at all surprised that Verizon Business is pondering WDM-PON technology, as he believes the hybrid GPON architecture initially will be deployed in a mixed neighborhood to deliver services to homes and businesses or homes and a business park. ,You might not need to push an additional wavelength into the splitter to take care of the homes, but you may need to push an additional wavelength or two to be split off to take care of the business in the business park,, he explains. ,You can easily see how the business demand could drive the bandwidth much higher into that splitter.Maybe down the road we,ll start to see much higher bandwidth requirements for different residential services,, he adds.
