MU Type Optical In-Line Attenuators MU MU Multi-position Mounting SC Fig.1 FC ■Features Save 16.7mm space 1. Smaller package Attenuator - MU Plug configuration Hirose’s original design combines a plug and attenuator into the same connector size of a standard MU plug,and the superior design enable to save a space using 4.5 mm pitch MU multiple adapters as shown in Fig. 1 and 2. 16.7mm Harsh Environment 2. Easy to Change attenuation level Easy to change the attenuation level by exchanging the attenuatin part with a simple push-twist lock as shown in Fig.3(See page 80).15 levels of attenuation are currently available : 0,1,2,3,4,5,6,7,8,9,10,12.5,15,17.5,and 20 dB 3. Insertion and extraction tool MU plug Adapter - MU Fig.2 Attenuator - MU PJ configuration Easy to change an attenuation part The MU standard tool is available as shown in Fig. 4. Back harness 5.
