“…Additionally, in an access network, optical fiber cables are deployed to the home: a fiber-to-the-home (FTTH) scheme under a passive optical network configuration. Thus, home users can have a wireline connection to the Internet with a speed of up to 1 Gb/s [4], [5]. However, as wireline-based communication limits service areas, and thus, limits ubiquitous connectivity to the network, mobile communication based on advanced radio technology is being dramatically developed to enhance connectivity.…”

SUMMARYA terahertz-wave communication system directly connected to an optical fiber network is promising for application to future mobile backhaul and fronthaul links. The possible broad bandwidth in the terahertz band is useful for high-speed signal transmission as well as radio-space encapsulation to the high-frequency carrier. In both cases, the low-latency feature becomes important to enhance the throughput in mobile communication and is realized by waveform transport technology without any digital-signal-processing-based media conversion. A highly precise optical frequency comb signal generated by optical modulation and the vector signal demodulation technology adopted from advanced optical fiber communication technologies help perform modulation and demodulation with impairment compensation at just the edges of the link. Terahertz wave, radio over fiber, waveform transport, coherent detection, multilevel modulation, radio on radio. key words: terahertz wave, radio over fiber, waveform transport, coherent detection, multi-level modulation, radio on radio

“…The advantages of using a PON as an access network include lower fiber deployment cost due to subscribers sharing a fiber line, a wider bandwidth, and lower maintenance cost for the fiber line. The video distribution service uses radio frequency (RF) overlay technology as an alternative to providing a high-definition television (HDTV) video service over fiber lines [4]. This RF overlay technology enables a service operator to deliver video contents in the same format as a cable TV (CATV) or satellite provider.…”

SUMMARYThe emergence of new services in the cloud computing era has made smooth service migration an important issue in access networks. However, different types of equipment are typically used for the different services due to differences in service requirements. This leads to an increase in not only capital expenditures but also operational expenditures. Here we propose using a service adaptive approach as a solution to this problem. We analyze the requirements of a future access network in terms of service, network, and node. We discuss available access network technologies including the passive optical network, single star network. Finally, we present a future service adaptive access/aggregation network and its architecture along with a programmable optical line terminal and optical network unit, discuss its benefit, and describe example services that it would support. key words: optical access network, passive optical network, network service, network topology

“…In fiber to the home (FTTH) systems, optical connectors are used in both indoor environments such as buildings and in outdoor equipment such as aerial closures [1]. For example, the SC connector [2] and the MU connector [3] are used in buildings, and the FAS connector [4] is used in aerial closures.…”

Optical connectors are used both indoors and outdoors. To confirm the durability of optical connectors employing PC connection in actual outdoor environments, since 1997 we have been performing a reliability test on an SC connector installed in a high temperature and high humidity location. We confirmed that SC connectors with optimized ferrule end dimensions, which are designed to provide physical contact connection with long-term reliability, have maintained good levels of optical performance in an actual outdoor environment for 10 years.
