CARE AND HANDLING OF OPTICAL FIBER
2.2.1. Safety
!
CLASS 1 LASER PRODUCT
2.2.2. Assembly
Assembly or repair of the laser sub-module is done only at Evertz facility and performed only by qualified
Evertz technical personnel.
2.2.3. Labeling
Certification and Identification labels are combined into one label. As there is not enough room on the
product to place the label it is reproduced here in the manuals.
•
There is no date of manufacture on this label as it can be traced by the bar code label placed on
the Printed circuit board of each Evertz plug-in module
•
The Model number is 7707MTA15-HD-W

2.2.4. Handling and Connecting Fibers
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical end
face of a connector before making a connection.
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 5 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 binder.
