NSN moves on to next-generation optical access

Nokia Siemens Networks (NSN) has announced it will not continue to invest in GPON, focusing instead on DSL and next-gen optical access (NGOA).

The decision, we believe, is attributable to a number of factors, including the truth that PON in any form is not universally feasible (where demand density is low it won’t recover costs at current price points).  In addition, vendors including ALU already have a substantial lock on the GPON business, and an NGOA that combines fiber remote and DSL or multimedia over oaxial cable access (MoCA) with PON could be the real long-term winner. We’re hearing interest in this last point from both carriers and equipment vendors.
