CARE AND HANDLING OF OPTICAL FIBER
2.5.1. 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 3000MVP modules are Class I, with a maximum output power of
7mW, and a wavelength of 1270 to 1610nm.
2.5.2. 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.
Fiber interconnections must be made securely. The Evertz fiber optical transmitters and receivers
come with SC interconnection housings built into the module. With this style of connector, the fiber
assembly and the housing assembly can only be connected in one way and with very good
repeatability. The fiber interconnect panel that is provided with each product can be ordered with
optional SC/PC, ST/PC or FC/PC connectors. The customer is required to provide the optical fiber with
the correct connectors to connect the modules together. SC/PC, ST/PC and FC/PC interconnection
housing and connectors as well as adapters are industry standards with many available sources.
2.5.3. Making Sure The Optical Fibers Are Clean
Dust particles on the ends of the optical fiber greatly increase the signal loss at interconnections, and
large dust particles can even obscure light transmission altogether. To minimize the effects of dust
contamination at the interconnections, the fiber should be cleaned each time it is mated or unmated.
When using interconnection housings to mate two optical fibers it is good practice to remove dust
particles from the housing assembly with a blast of dry air or by wiping the end of the fiber connector
with the pre-moistened tissue you received with the optical module before mating it to the module.
Whenever a fiber is unmated it must be covered immediately. Most fiber manufacturers provide a
plastic boot that fits over the ferrule body for this purpose.

DISPLAY SETUP
When using standard video resolutions (XGA, SXGA, 720p, etc.), the 2430GDAC-WARP outputs video
with an upright orientation. Orient the connected display device in it's upright position.
When using WARP resolutions (WXGA-WARP, etc.), the 2430GDAC-WARP outputs video that is
rotated 90° clockwise. Orient the display such that it is rotated 90° counter-clockwise relative to its
upright position (see Figure 2-2).
