“Where PON technologies are used for residential broadband services, 2.5-Gbps GPON will remain as the dominant technology due to its lower price and sufficient speeds,” explains Alam Tamboli, senior analyst at Dell’Oro Group. “However, for a number of growing use cases such as business services and mobile backhaul, next-generation PON technologies have capacities and capabilities that current generation technologies lack.”
Such next-gen platforms include 10G-EPON, XGS-PON
, and NG-PON2
. “10-Gbps EPON has already begun shipping strongly in China, where current generation PON is widely deployed,” Tamboli continued. “Shipments of XGS-PON and NG-PON2 remain small for now, but we anticipate that XGS-PON will grow more rapidly. XGS-PON and its 10-Gbps symmetric bandwidth should meet operators’ needs for business services and mobile backhaul.”
The Dell’Oro Group “Broadband Access 5-Year Forecast Report” provides an overview of the broadband access market with tables covering manufacturers’ revenue, average selling prices, and port/unit shipments for Cable, DSL, and PON equipment. Network infrastructure equipment includes cable modem termination systems (CMTS); digital subscriber line access multiplexers (DSLAMs) by technology, including ADSL, ADSL2+, G.SHDSL, VDSL, and Gfast; and PON optical line terminals (OLTs). Customer premises equipment (CPE) technology covered in the report reflects voice-over-IP (VoIP) or data-only.
