CAUTION! Any extreme stresses onto the optical cable could degrade the
optical performance or damage the fiber.
• Do not pull on the fibers ! • Never bend an optical cable more sharply than a 35mm radius! • Bending over any sharp edges may damage or break the fiber! • Avoid excessive heat near cables!
• All optical connectors should remain covered with dust cups in place when not in use. Cleaning & Mating Instructions for Optical Connectors
• Clean both connectors prior to mating by using a high-grade isopropyl alcohol and a cotton swab.
• Allow connectors have to dry before mating. • Insert the connector ferrule into the appropriate adapter smoothly. • Do not over-tighten the connectors.
• Specifications for the eol series switches are based on an optimal connection. If the resulting values are unacceptable, please repeat the cleaning procedure and start again.
The Fiber optical switches from LEONI are based on a unique
patented micromechanical / microoptical concept. They provide
excellent parameters, high flexibility and long term stability
for various applications. The switches are available for a broad
wavelength range from the ultraviolet to infrared and can be
fabricated with practically all possible fiber types.
The switches can be easily integrated into an existing system
due to maximum input power of 450 mW and standard inter-
faces (RS232, I2C, TTL, USB, optional Ethernet). High channel
numbers can be achieved without cascading, e. g. eol 1×16.
With cascading almost any desired combination is possible.
