NOS EZFieldMate Field Termination Kit offers a simple, efficient, and cost-effective
process for field connectorization of single mode or multi-mode fiber optic cable
at the tightest factory specifications. Minimal training is required for installers
and technicians to become proficient and certified. The kit includes all tools,
parts and instructions needed to complete the termination of fibers in the field,
which are compliant with GR-326-CORE & Telcordia GR-1081-CORE requirements.
NOS can customize the kits to contain various connector types/polishes to meet
should be installed from the originating head-end i.e., the electrical or telecommunications
closet. Once the pathway has been established, it is important the layout of the
pre-fabricated junctions be installed first. Junctions/intersections lengths are
standard: 12 inches wide or less come 2 feet in length and junctions/intersections
more than 12 inches wide come 3 feet in length. This allows for field measurements
to be taken before installing the cable tray. If the straight sections are installed
first, it will cause unnecessary field adjustments. Each section has loops at
each end. When the sections are connected, the loop on the bottom aligns under
the galvanized masked area of the adjoining section. The loop on the side slides
into the outside loop guide. Once the trays are aligned, install the 5/16 inch
carriage bolt (included) through the loops with the treaded end to the outside
of the tray. Install and tighten the flanged nuts with a ½ inch socket.
This reduces the chances of damage when pulling the cables. Elevation may be adjusted
by using pre-fabricated drop with universal hooks (Fig. 1) or individual straight
sections with universal hooks and extenders (Fig. 2). Adjust the length with the
Cable-Mgr. cable tray extensions CM-58 (Fig. 3). The extensions fit into the side
guides facilitating adjustment of the tray up to 6 inches on each end. It is not
recommended that the cable tray be cut as it will interfere with the grounding
characteristics and UL classification..

is a Cable Tray System?
the National Electrical Code, a cable tray system is "a unit or assembly
of units or sections and associated fittings forming a rigid structural system
used to securely fasten or support cables and raceways." What does this
* Cable trays support cable the way that roadway bridges support traffic.
* A bridge is a structure that provides safe passage for traffic across open spans.
* Cable tray is the bridge that allows for safe transport of wires across open
spans. * Therefore, think of cable tray as the structural component of a building's
standards / guidelines are available for cable tray systems?
1. The National Electrical Code publishes the standards for all types of electrical
applications. Articles 318, 250, and 800 cover various aspects of cable tray systems.
2. NEMA, (National Electrical Manufacturers Association), is an association comprised
of the major cable tray manufacturers in the industry. This committee has published
three documents to date: NEMA VE1, FG1 and VE2.
NEMA VE1 covers general cable tray definitions, manufacturing standards, performance
standards, test standards, and application information. Free download of this
document is available on the NEMA website.
NEMA FG1 addresses the standards for fiberglass cable tray systems. Free download
of this document is available on the NEMA website.
NEMA VE2 is a cable tray installation guideline which covers receiving and unloading
material, storage of material, and general installation practices. Free download
of this document is available on the NEMA website. 3. CTI, (Cable Tray Institute),
is a trade association comprised of the major cable tray manufacturers in the
industry and was formed to provide specifiers, designers, and installers information
on the advantages of using cable tray systems over other types of products. (i.e.
conduit, ladder rack, etc.)

that I know what types of cable trays are available, what configurations are available?
1. Straight sections are available to route cables in a horizontal or vertical
plane. 2. Fittings are available to route cables in various directions in
either the horizontal or vertical planes. Typical examples of fittings include
elbows, tees, crosses, and risers. Each of these fittings are available in various
radii and bend angles. 3. Covers are accessories and shouldn't be in here
unless splices etc. are included.
selecting the type of cable tray and configuration required, what support methods
1. Trapeze Support (Single or Multi-tier) 2. Hanger rod clamps, "J"
hangers 3. Center Hung Support 4. Wall Support 5. Underfloor Support
6. Pipe stanchions or other structures
of these support methods are preferable in different applications. For instance,
trapeze supports may be desired in an application where cables will be pulled
through the cable tray. Center hung supports, on the other hand, are generally
used when cables will be installed from the side of the cable tray. Center hung
supports are especially useful when future cable additions are desired. Wall supports
and underfloor supports are useful when ceiling structure is not available or
undesired. Outdoor installations are controlled by the structures available to
support the cable tray. Before selecting the type of cable tray, cable tray
configuration(s), and support method desired, what additional information do I
need to supply to the cable tray manufacturer for them to best understand and
satisfy my needs?
1. Where? Job site and installation considerations 1. Outdoor 1. supports
available affect the length and strength requirements 2. environmental loads,
ice, wind, snow, and possibly seismic 3. corrosion requirements affect the
materials and finishes 4. classified hazardous locations affect the cable
types acceptable 2. Indoor 1. support locations available affect the
length and strength of the system 2. industrial installation may require a
200 lb. Concentrated Load 3. commercial or institutional installation may
make system appearance, system weight, and space available important factors
4. environmental air handling area may affect cable types, cable tray material,
or cable tray type and need for covers 5. classified hazardous locations affect
the cable types acceptable
2. What? 1. Type and number of cables to support 1. NEC cable fill requirements
dictate size, width and depth, of system 2. cable support requirement may
control bottom type 3. largest bending radius of cable controls fitting radius
4. total of cable weight determines load to support 2. Future requirements
1. cable entry / exit freedom 2. design partially full or an expandable system
3. support type to allow for needs
