Commonly
called jumpers or patchcords, these basic fiber assemblies range from more generic datacom jumpers to single fiber, large
core cable designs utilizing more robust and customized components. Optical coatings to enhance the fiber’s
properties of minimized reflection or cutoff wavelengths can be added for jumpers, as well as any multi-fiber assembly.
We also offer high power SMA's in several versions.
A bundle can be thought
of as a jumper assembly, but with many more fibers, and a virtually unlimited number of options available for fiber types,
cable materials and end terminations. Many of these bundles may contain some of our standard
types of terminations. However, many products are OEM based and therefore require a specific design that
can be manufactured by one of our top quality suppliers to our exacting standards.
The fibers can be arraigned into
round, ring, continuous or multi-segment line or arc, or packed into 2D shapes or arrays. V-grooves in
the base material or silicon are commonly used for interfacing to diode lasers and are generally optically coated to
minimize de-stabilizing reflection of energy from the polished fiber surfaces back to the diodes or interface hardware.
These assemblies are the same
as bundles, but either one end or both ends can be separated into a countless number of standard or custom-designed terminations
and fiber configurations to match the physical and optical characteristics required at the terminations.
These assemblies can be used to split or combine optical power. The only limitation is that the number of fibers per
furcated leg must be at least one!
Bundle assemblies using SM, 50 or 62.5um graded-index fibers generally
made for datacom applications are commonly called harnesses and use standard datacom connectors such as LC, SC, MTP, MT-RJ,
etc. for short assemblies intended for use inside enclosures. More robust inter-cabinet connections are
called trunks.

These assemblies are immersed into a solution in order to obtain spectra of its constituents and are commonly
referred to as a Dip Probe or a Transmission Probe. The basic design consists of two fibers with a lens
that collimates the light from one fiber through an open section through which the liquid can pass. The light
is then reflected off of a mirror where it passes through the liquid and lens a second time, and is refocused onto the
second fiber for transmission to the analyzing instrument. For the standard probe design, the liquid absorption pathlength
is double the physical opening of the replaceable tip. Other designs may call for larger probes or more robust probes
designed to meet harsher conditions. These adapters are designed to fit onto a connector or custom termination, or can be designed to be mounted
onto a piece of equipment. Their purpose is to image or collimate the light from the fiber(s) or from a source to the
fiber(s). Generally they consist of a machined part with the optical elements mounted in place, with or without focusing
adjustment. Optical adapters also consist of vacuum feedthroughs where optical testing through a vacuum chamber is desired.
This can be accomplished using a variety of modified vacuum flange designs, such as the variety of conflat flanges available, and
an internally sealed fiber and/or optics. This product class generally contain no optical
components, but are for mounting or enclosing optical components or assemblies, and are made specifically for OEM clients
and their applications.
