| How to Cleave and Splice Optical Fibers
In any signal transmission system, the low loss splicing of transmission line segments is
fundamental to optical performance and reliability. The precise nature of fiber optics demands a
high level of skill and attention to detail on the part of the fiber technician. Unlike copper wire
that relies on simple contact for a low attenuation splice, optical fibers must be correctly aligned
and held in position to transfer a maximum amount of light across the splice. In addition,
because the glass fiber is vulnerable at the splice point, it must be protected from the elements
and from mechanical stresses
How
to Cleave and Splice Optical Fibers will demonstrate the correct methods of preparing,
cleaving, splicing and protecting optical fibers. Learning the proper techniques is essential for
any fiber technician.

| | How to Perform an Optical Loss Budget
When designing a fiber optic system, one of the most important design elements is the "Optical
Loss Budget", a detailed calculation of the optical power available at the output of the
transmitting source, the optical power required at the receiver's detector and the dissipation or
attenuation of optical power in the optical path between transmitter and
receiver. In essence,
the Optical Loss Budget is a statement of how the optical power available will be used.
Learn how to do optical loss budgets for Local Area Networks per the TIA/EIA 568A standard
and for Wide Area Networks in telecommunications and CATV networks using singlemode fiber.
In addition, not to exceed loss budgets for contractors are demonstrated.
