Page 10: Product Overview
Product Overview Newport's 1x2 and 2x2 Prism Switch provides channel selection from one or two input fibers to two output fibers, using a moving prism between fixed collimators. Newport's 1x2 and 2x2 switches are actuated electrically and require +5 VDC to switch position. -
Page 11: Section 2 - Switch Control
Section 2 Switch Control The four-pin electrical interface is used to control and monitor switch position. The electrical connector is Molex P/N 22-23-2041, and mates with Molex P/N 22- 01-3047 or equivalent. Pin 4 is the position sensor output. The output alternates between normal open contact and normal close contact (low or high signal) depending on the switch position. -

Page 17: Section 4 - Handling Fiber Optic Components And Cables
Section 4 Handling Fiberoptic Components and Cables Handling Fiber Optic Cables The user's switch may come with fiber pigtail outputs. Treat cables with care to avoid cable damage and minimize optical loss. The minimum bend radius for most optical cables is 35mm. Never bend an optical cable more sharply than this specification. -
Page 18: Storing Optical Connectors
In order to obtain the most stable, repeatable • optical performance, immobilize optical cables using wide pieces of tape or some form of mechanical cushion after the optical cables have been connected. Figure 4.1: Fiber Optic Component Storing Optical Connectors All switches are shipped with dust caps in place covering all optical connectors. -
Page 19: Mating Optical Connectors
To clean with alcohol and a swab, dab the tip of a cotton swab in alcohol and then shake off any excess alcohol. The tip should be moist, not dripping wet. Stroke the swab tip gently across the surface of the connector and around the connector ferrule. - Page 20 Optical power trending (slowly increasing or decreasing) is caused by the slow evaporation of alcohol trapped in the connection. Continue to monitor optical power until it stabilizes. If the loss is unacceptable, re-clean the connector and start again. Section 4 – Handling Fiber Optic Components and Cables...
