Seven-core multicore fiber transmissions for passive optical network

A multicore optical fiber for distributed sensing

With advancements in optical fiber technology, the incorporation of multiple sensing functionalities within a single fiber structure opens the possibility to deploy dielectric, fully distributed, long-length optical sensors in an extremely small cross section. To illustrate the concept, we designed and manufactured a multicore optical fiber with three graded-index (GI) multimode (MM) cores and ...

Miniature multicore optical fiber vibration sensor.

We demonstrate a compact and versatile interferometric vibration sensor that operates in reflection mode. To build the device, a short segment of symmetric strongly coupled multicore optical fiber (MCF) is fusion spliced to a single-mode optical fiber (SMF). One end of the MCF segment is cleaved and placed in a cantilever position. Due to the SMF-MCF configuration, only two supermodes are excit...

Multimode Passive Optical Network for LAN Application

Reliability and Cost Benefit Analysis of Protection Schemes for Passive optical Fiber Network

This paper gives a model for finding the reliability and cost of passive optical fiber networks (PONs). Mathematical modeling of various PONs has been done using to determine the cost and reliability for deployment at the access domain. It is observed that there is a trade-off between cost of protection and the reliability level that we attain from adding redundancy, as duplication in PON netwo...

Ethernet Passive Optical Network (epon)

Ethernet Passive Optical Network (EPON) is a point to multipoint network architecture and suitable for carrying Internet Protocol Television (IPTV) service because it provisions higher bandwidth for downstream, but it also cannot satisfy the bandwidth requirement of tens of thousands of IPTV channels and carry these channels simultaneously. Previous papers had proposed some multicast mechanisms...
