Optical transmission links are generally composed of optical fibers, amplifiers, and filters. In this paper, we present a channel reconstruction method (CRM) that extracts physical characteristics multiple link components such as longitudinal fiber losses, chromatic dispersion (CD), amplifiers’ gain spectra, filters’ responses, only from receiver-side (Rx) digital signal processin...

High-data-rate ground-to-space optical links are envisioned to be an alternative and more probably a next step to radio-frequency links, after the Q/V band still under development [1] for the feeder links of next generation high throughput satellites. Indeed, optical links allow a significant increase of the available spectral resources per link. This enables a drastic reduction of the number o...

We experimentally investigate the optical loss of graded-index (GI) core polymer optical waveguides with a 45-degree mirror on their one end fabricated using the photo-addressing method. In addition, we also theoretically analyze the loss of GI square-core waveguides with mirrors using a ray-trace simulation tool. Then, in the waveguide based optical link including the optical path conversions ...

The ingress and egress nodes in an all-optical network have an electronic inand egress part and an optical switch. This work analyses various architectures for interconnection of the "electronic" and "optical" parts of the network in order to tolerate single optical switch failures and single optical link failures. The architectures studied are: non-redundant (reference), fault tolerant optical...

Telecommunication traffic (voice, data etc.) is increasing day by day. So to meet the capacity demand, in this paper we have designed and verified a high capacity optical fiber communication system through simulation. We simulated a 40 Gbps single optical fiber link for telecommunication traffic transmission which could be possible to implement in developing countries with few modifications in ...

The effects of aberration on the Bit-Error-Rate (BER) and reliability of free- space optical (FSO) communication links are investigated. Based on aberrated divergent rectangular partially coherent flat-topped beam formula on the receiver plane and considering the atmosphere losses due to absorption and scattering, numerical values for Power In Bucket (PIB), Signal to Noise Ratio (SNR) and BER a...

A fiber-optic broadband signal distribution link based on a millimeter-wave self-heterodyne transmission/optical remote heterodyne detection technique was developed. To avoid having to use expensive optical and millimeter-wave devices to construct a frequency-stable fiber-optic millimeter-signal transmission system, a millimeter-wave self-heterodyne transmission technique was used, in which tra...

In this work we present a model for the design and optimization of the video distribution link in the next generation optical access network. We analyze the video distribution performance in a SCM-WDM link, including the noise, the distortion and the fiber optic nonlinearities. Additionally, we consider in the model the effect of distributed Raman amplification, used to extent the capacity and ...

We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the telecommunication network. The optical reference signal is in...
