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). <IMAGE> |
