CARE AND HANDLING OF OPTICAL FIBER
2.1.1. Safety
!
Never look directly into an optical fiber. Non-reversible damage to the eye can occur
in a matter of milliseconds.
The laser modules used in the Evertz fiber optic modules are Class I, with a maximum output power of
7mW, and a wavelength of 1270 to 1610nm.
2.1.2. Handling and Connecting Fibers
"
Never touch the end face of an optical fiber.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that you maintain a minimum bending radius of 3 cm to avoid fiber-bending loss that will
decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come with
cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the
frame that does not have a suitable I/O module. For further information about care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design chapter of this manual.
