Optical receiver design for high optical return loss

Applied Optics, 1992
A new fiber pigtailed optical receiver design using a single gradient-index rod lens with a beveled exit face achieved a broadband optical return loss of > 65 dB, which was limited by the diffuse reflection from the photodetector front surface. By contrast the optical return loss for a receiver with an unbeveled lens exit face and an on-axis optical ...

Structural return loss phenomenon in coaxial cables

Proceedings of the IEEE, 1970
This paper presents a study of the structural return loss (SRL) phenomenon pertaining to coaxial cables. Basic equations are developed, the effect of periodic changes in the physical structure of the cables is analyzed, measuring principles and techniques are discussed, and a method of fault location using the SRL test technique is given.

Return loss characteristics of optical fiber connectors

Journal of Lightwave Technology, 1996
This paper describes the return loss characteristics for four typical contact type connectors: perpendicular and oblique endface connectors employing either physical contact or contact via index matching material. The high index layer on the polished fiber endface and the index matching material, which are important connector parameters, are ...

Simplified De-embedding for Return Loss Estimation

2021 IEEE International Joint EMC/SI/PI and EMC Europe Symposium, 2021
In some applications, it is shown that the peak return loss of a Device Under Test (DUT) can be accurately estimated from a knowledge of the magnitude of the s-parameters of the test fixture and the assembly. Numerical results illustrate advantages and limitations.

Impedance and return loss performance

Electrical Engineering, 1958
THE DESIGN of intercity trunks under conditions of nation-wide dialing and the greater number of permissible links between terminal offices has required a reappraisal of transmission objectives, including terminal return losses.

Return loss requirements for optical duplex transmission

Journal of Lightwave Technology, 1987
There has recently been considerable attention given to bidirectional transmission over the same optical fiber. One of the impairments associated with this type of system is receiver sensitivity degradation due to reflected power. This paper presents an analysis of this impairment and compares it with experimental results.

Three Stories of Loss and Return

Cultural Studies ↔ Critical Methodologies, 2001
"Land of My Fathers," "Another Mother," and "Someday He'll Come Along" were written for and presented at sessions chaired by Norman Denzin at the Midwest Sociological Society meetings in 1998, 1999, and 2000, respectively. Along with two earlier pieces, "My Mother's Car" and "Sarah and Me," they are intended to answer Denzin's call for new stories ...

Loss persistence and returns in the UK

Accounting and Business Research, 2015
In this study, we examine whether estimated loss reversal probabilities are fully reflected in UK stock market prices. Overall, we provide evidence of varying degrees and types of loss firm mispricing with respect to estimated loss reversal probabilities.

Estimating Millimeter-Wave-Circuit Insertion Loss from Return-Loss Resonances

2007 IEEE International Vacuum Electronics Conference, 2007
Measurements of RF loss in millimeter- wave circuits typically are limited to frequencies that are impedance matched to permit transmission through the circuit. An alternate cold-test method can provide estimates of such RF absorption for frequencies that are not matched by measuring return- loss resonances without regard for coupling conditions.
