Compact-size optical amplifier
First Claim
1. An apparatus for organizing the components of an optical amplifier, comprising an active light guide section (7,10), a dichroic coupler (5,8), a pump laser source (6,9) acting on the active light guide section (7,10) through the dichroic coupler (5,8), a directional coupler (3,11) associated with a respective optical meter (4,12), and connection light guide sections (14) between the various components, characterized in that said apparatus comprises:
- an auxiliary frame (21) accommodating both the dichroic (5,8) and directional (3,11) couplers as laid parallel to one another and to a longitudinal axis (A) of the auxiliary frame (21), and the optical meter (4,12);
a organizer frame (28);
two winding drums (30) provided on the organizer frame (28) side-by-side in spaced relationship, the active (7,10) and connection (14) light guide sections being wound on the drums (30); and
a main frame (15) having the organizer frame (28), auxiliary frame (21), and pump laser source (6,9) mounted thereon.

Abstract
The amplifier (1) comprises two active light guide sections (7,10), two dichroic couplers (5,8), two pump laser sources (6,8) acting on the active light guide sections (7,10) through the dichroic couplers (5,8), two directional couplers (3,11) associated with two respective optical meters (4,12), and light guide sections (14) for interconnecting the various components. The dichroic (5,8) and directional (3,11) couplers, and the optical meters (4,12), are pre-assembled onto an auxiliary frame (21); the active (7,10) and connection (14) light guide sections are wound on two drums (30) provided on an organizer frame (28). The auxiliary frame (21), organizer frame (28), and pump laser sources (6,9) are accommodated on a main frame (15).
