JW3303 handheld variable optical attenuator
JW3303 handheld optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, therefore, JW3303 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV).

Features

* stepwise attenuating by circumgyrated dial: attenuating step 0.05dB
* Provide with the function of displaying dB and dBm attenuating value
* 10 minutes Auto-off function can be activate and deactivate with keypad operation.
* After off the instruments, the system will have the memorizing of the attenuating value and the attenuating step, in order to restore the system back to the previous shut down state when open the instruments next time
* Portable, rugged, lightweight; Easy to use.

JW3306B Optical Fiber Identifier
JW3306B Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the bended fiber. When the traffic is present,the intermittently audible tone is activated.

The JW3306B optical fiber identifier also recognize the modulation like,270Hz,1kHz and 2kHz .When they are used to detect the frequency, the continuously audible tone is activated.There are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0. The JW3306B optical fiber identifier is powered by a 9V alkaline battery .

Features

* Easy-to-use with “ONE KEY” operation.
* Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning.
* Displays the relative core power
* More accurate test with Sunshade
* Easy-to-replace adaptors
* Durable metal housing and quality construction
* Lower power indication
