Page 10: Installation
2405/2407LTA Standalone L-Band Fiber Optic Transmitter INSTALLATION The 2405/2407LTA comes in a die-cast enclosure with integral mounting flanges. It is recommended that the enclosure be mounted on a flat surface with the connectors facing down. For units with the -WP option that are exposed to the elements, while not required to prevent water ingress into the unit, good outdoor installation practice suggests protecting connectors with a wrap of Scotch 130C rubber tape followed by Scotch Super 88 vinyl tape, or equivalent. -

Page 12: Labelling
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. -
