Description

Introduction

This document describes a methodology that is recommended for
engineering a single-mode fiber optic transmission system. The
methods address the design of a regenerator section in which the
transmitter and receiver come from the same vendor. As an initial
step, only laser systems operating in the 1300 nm region over a
class IVa' dispersion unshifted fiber are being considered. As
engineering technology improves, this document will be revised to
include systems operating in the 1550 nm region. For systems using
multilongitudinal mode lasers above approximately 0.5 Gb/s, the
calculated dispersion limited lengths may be conservatively
low.

As detailed below, suppliers should provide, if requested as
part of system documentation, parameters which allow the design of
regenerator sections. Some of the parameters in this document will
be measured via FOTPs and OFSTPs. The transmission design
information for terminal and regenerator station equipment is
covered in Section 2, while that for outside plant cable is covered
in Section 3. Worksheets 1 to 4 have been provided as examples of
forms which could be used in gathering the transmission design
information. Section 4 discusses how this information is used in
the design and analysis of regenerator sections, which can be
performed by either users or a system integrator.

In the sections which follow, the transmission design parameters
are specified by their worst case values. It is the option of a
user to require that suppliers guarantee the worst case values over
the lifetime of their respective system components. Some users or
system integrators may desire to perform analysis and design
calculations via a statistical approach and to request statistical
values of the parameters. The statistical approach is covered in
Appendix 1. Custom engineering may further optimize the design.
