scope:

This part of IEC 61282 describes a model developed as a tool to assist the physical layer committee of the gigabit ethernet (IEEE 802.3z) standard to understand potential trade-offs between the various link penalties associated with laser-based backbone links. The purpose of this technical report is to document the model as used by gigabit ethernet and to identify how it was used to develop the standard specifications.

This technical report presents the theoretical model. Experimental verification is also presented for links operating at valid gigabit ethernet wavelengths of 780 nm, 850 nm and 1 300 nm.

The technical report is organized as follows. In Clause 2, a simple theoretical prediction of laser-driven links is presented. Clause 3 contains the description of the experimental measurements and the experimental verification of the theoretical predictions. Finally, Clause 4 contains some example calculations and discussion of the results and use of the model.
