It can test 8 of 14-pin butterfly lasers at same time.It allows you to connect directly to your 8016 , 9016 , 9008 controller with the proper cables.This Newport 8-Channel Butterfly Fixture, Laser Diode Drawer, Water Jacketed with TEC with Rackmount. This drawer is unique in that it has built adapter at the detector to align FP3-FH1 bare fiber holders. There are 8 large-area photodiodes to monitor 8 lasers. 8-photodiode array comes with a ribbon cable, but its operating wavelength is unknown.Designed For:1. Testing (8) 14-pin Butterfly, Pigtail Laser Diode Packages Simultaneously2. Interface to (8) FP3-FH1 Bare Fiber Holders (Bare Fiber Holders will be sold separately)3. (8) User Configured Jumper Blocks for communications with system (Only two of the 8 Jumper Blocks for type-1 laser at the top of the 6th photo below are included in this sale ! ). It comes with one configuration board 708-CONF-1 (for type-1 laser) and one configuration board 708-CONF-2 (for type-2 laser), as shown at last photo below, so you can test one type-1 laser and one type-2 laser at the same time.
