A fiber loop carrier for broadband service in fiber to the curb

摘要

The invention DS1 (1.544Mbps), DS1E (2.048Mbps), DS3 (51.84M), 10BaseT, STM-1 (155.520Mbps) receives a signal by using an ATM cell multiplexing STM-1 / STM-4c (622.080 Mbps) relates to a multiplexed into a signal, and the opposite side of ONU (Optical Network unit) function and a demand-dense broadband subscribers optical transmission apparatus for performing dysfunction (the Host Digital Terminal (HDT for optical transmission in) quot;), wideband Local Loop is used for, in addition to traditional voice, ISDN service, can be accommodated at the same time seems to be the multimedia services to surge in future demand and using the ATM technology and bus routing techniques were used to maximize the efficiency of the subscriber bandwidth. In addition, voice and ISDN service when the device was removed facing channel unit in HDT and to enable the heat exchanger and a solid line is connected to IDLC (Integrated Digital Loop Carrier) function using the DS1E not, STM-1, DS3 for the wireless connection of Internet subscribers , by various service to the 10BaseT signal it was given the flexibility to network configuration environment, compared to the conventional implemented economically and efficiently by maximizing the carrying capacity per self is used as an optical transmission device in the affairs for demand-dense optical network optical cable screen subscriber It can be transferred to a variety of services.
