■Features

1. Smaller package

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.

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

The MU standard tool is available as shown in Fig. 4.

4. Maximum input power :100mW

5. Please contact us if you have any requests.

Hirose will offer excellent solutions to meet

your requirements.

■Applications

Power level adjustment of optical fiber communication

networks.
