Despite Technical Difficulties with 40G, Some IXC Engineers Confident It Can Work

Implications: 1.      Several interexchange carriers (IXCs) can barely get 40G turned up. 2.      The high level of sensitivity involved with its operation means that technicians need to be very meticulous. 3.      Given the inherent problems at 40G, expectations are that 100G for long haul will be a tremendous challenge.

Analysis:  If craftspeople in IXC networks do not clean the connectors properly, it cannot get turned up.  A lot of times network managers have discovered that these technicians are not disciplined enough to do it right the first time.  Nevertheless, there are a number of engineers, including at AT&T, who are apparently adamant that 40G will be realized.StrataLight’s scientists are also working very hard to help smooth the way for the higher rate capability.  

The very tough obstacles with 40G make confronting 100G that much more daunting.  At present, there is the belief by certain long-haul planners that they will have to fusion splice everything in order to achieve this level of capacity – making its prospects questionable.  In addition, the lasers at 100G get incredibly hot.  So, it will require developing a laser, which is cost-effective, that will not burn up.
