Flexible optical access and in-building networks

IEICE Proceeding Series, 2007
Optical routing in acces or in-building networks can improve the flexibility with which services are provided to the end users. It also can increase the systems´s operational efficiency by remarkably decreasing the call blocking probability.

Optical access network technologies for future radio access networks

2017 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2017
This paper describes optical access network technologies that support future radio access networks. Packet-based BBU is expected to accommodate multiple services and PON with low-latency scheme is a promising candidate to for MFH transmission in future radio access networks.

DPSK for optical access networks

2012 IEEE Colombian Communications Conference (COLCOM), 2012
The development of technologies for optical access networks and user demand for more bandwidth has enabled consider increasing rates and improve the current coverage of access networks. Currently there are various ways to achieve this goal, one relates to the use of modulations in the signal processing in both the OLT and the ONU.

Introduction to Optical Access Networks

2020
Fixed-access networks have had a tremendous impact on society over the last few decades enabling residential broadband services and being a driver for the digitalization of society. With increasing broadband speeds, optical access technologies are playing an increasingly important role for fixed access.

An Introduction to Optical Access Networks

2010
With the current continuously growing bandwidth demand, it is apparent that conventional broadband access solutions will quickly become bottlenecks in terms of bandwidth provision. In this chapter, the authors analyze the present global challenge for extended bandwidth provision in the scope of the fast developing electronic communications sector ...

Coherent Optical Access Networks

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2011, 2011
Coherent technology is the only viable solution to fulfill requirements regarding data rate, reach and splitting factor for optical access. Cost of optics is compensated by savings in system design to achieve an economic solution.

Developments in optical access networks

BT Technology Journal, 2002
Optical fibre access network technology has become more complex over the last few years with bit rates steadily increasing. PON systems are available with bit rates in the range 155 Mbit/s to, currently, 622 Mbit/s. Newly designed systems, both PON and point-to-point, will allow this trend to continue with 2.5 Gbit/s systems becoming practicable in the

Coherent Optical Access Networks

2018
The constant increase in IP traffic, mainly driven by the growth of the number of connected users and the demand for bandwidth per user, has profoundly influenced the evolution of optical communication systems as a whole, including fiber-based access networks, which constitute the last mile of an optical system, directly connecting the edge IP network ...

Active optical access networks

Communications Engineer, 2003
While fast connections over copper are possible, higher bandwidth requirements can only be met with fibre connections in the local loop. This paper reviews the structure and operation of active optical access networks in providing telecom services to the user.

Optical Amplifiers in the Access Networks

Optical Amplifiers and Their Applications, 1994
The application of optical amplifiers to access networks is expected to have the greatest impact on optical video distribution systems. Among optical amplifiers, EDFAs are being commercially used in video trunk line systems because of their advanced maturity. This paper surveys the applications of optical amplifiers.
