Chapter 1: LCX Fiber Panels
1.1General Information
Telect manufactures LCX fiber splice panels and LCX fiber patch panels of various densities to suit
network fiber splice, patching and routing requirements.
•2RU through 4RU models vary in density from 24 to 144 fiber terminations. All have spring-
hinged removable front and rear doors (Fig. 1). Knockout holes at the top and bottom of the panel
allow for routing from splice panels to patch panels (and between patch panels) vertically within
the rack. Hole pattern and positions are compatible with panels offered by other manufacturers,
allowing expansion and replacement of those systems using the LCX panels.
•Interconnection and cross-connection cabling from above or below enter at the two front corners
of each LCX panel via isolation hooks and/or radius control arcs (sold separately) installed on-site
to suit the application and entry/exit direction. Eight split arcs and 24 snap-in cable rings are
standard with each panel. Telect also offers optional kits (KIT-CMHOOK, KIT-CMRHOOK, KIT-
CMARK) to satisfy cable management practices requiring multiple arcs or guide posts to separate
and isolate groups of fiber cables.
1RU models have densities up to 24 fiber terminations. Instead of front or rear doors, 1RU panels have a
removable sliding drawer that can be extended at the front or rear of the chassis to maximize access to
fiber connections. Pivoting arcs at corner entries and exits provide cable management. Entry and exit
positions are compatible with entries and exits of other Telect LCX panels and those of other
manufacturers.
1.1.1 LCX Fiber Splice Panels
Telect offers four sizes of LCX fiber splice panels (1RU-4RU) to accommodate up to 144 splices. Each
removable splice tray (LCX-S-HSF) holds up to 24 splices along with about five feet (1½ meters of fiber
cable storage:
•For a 1RU splice tray, all fiber (subunit, cable and strands) is stored on the tray
•For a 2RU, 3RU and 4RU splice tray, all subunit and interconnection cable storage is below the
trays
Trays easily slip free of the panels to allow splicing. Storage spools or arcs, along with splice holders, are
mounted directly on the tray, eliminating the need for special splice cassettes.
1.1.1.1 LCX 1RU Fiber Splice Tray –24-Splice Capacity
LCX 1RU fiber splice trays use sets of pivoting arcs for routing and storing both fiber subunits and
interconnection cable.

IFC stranded cable from the splice vault is secured at either rear corner of the LCX splice panel by an
optical cable clamp. A single clamp comes with two rubber bushings to fit either a 12- or 24-fiber IFC
riser/plenum cable.
The following illustration shows a clamp holding an IFC cable installed on the rear rack flange near the
entry/exit of an LCX 1RU splice panel. The interconnection cables enter the tray at one of the other
corners of the splice tray.
1.1.1.2 LCX 2RU, 3RU & 4RU Fiber Splice Trays
A 144-splice 4RU LCX panel (LCX-S141) that houses six splice trays is available but not pictured.

•48-splice 3RU LCX panel, 2 splice trays
•72-splice 4RU LCX panel, 3 splice trays
•96-splice 4RU LCX panel, 4 splice trays
2RU, 3RU and 4RU fiber splice trays use storage spools to route and store stranded fiber.
The following figures show termination capacities of LCX 2RU, 3RU and 4RU fiber splice panels.

IFC stranded cable from the splice vault is secured at either rear corner of the LCX splice panel by an
optional cable clamp. A single clamp, KIT-CLMP, fits all sizes of IFC riser and plenum cable. (Fig. 12
shows a clamp holding a 96-strand IFC cable installed at the left rear corner of an LCX splice panel.)
Cable rings in the rear portion of the panel lead the IFC tubes to one of the front corners of the splice
trays. The interconnection cables enter the tray at the other front corner of the 2RU, 3RU and 4RU splice
tray.

Chapter 2: Applications
2.1 Interconnecting IFC to Network Elements
Figure 26 shows a simple interconnection scheme where OSP is spliced at a vault to IFC plenum or riser
cable, which is then spliced at a LCX fiber splice panel to the network elements.
Note: Stranded or ribbon fiber should always enter or leave LCX panels in tied-down tubes, sheathed

2.3 Cross-connecting Network Elements
In a variation of 2.2 Interconnecting Network Elements, NE1s and NE2s are connected to the rear of two
LCX fiber patch panels with the fronts reserved for patch cords to cross-connect the two.
Figure 28 shows a stylized version of this application.
2.4 Cross-connecting Combinations
LCX fiber patch and splice panels can be used in
combination to cross-connect IFC to network
elements.
Figure 29 shows a 48-fiber LCX combination panel
(a 48-fiber LCX splice panel bolted to a 48-fiber LCX
patch panel). After the incoming IFC is spliced, the
fiber strands are passed through the 1.5-inch (38.1
mm) diameter hole in the top of the splice shelf to
the patch shelf.
Flexible edge protectors are used to protect the
unsheathed fiber strand passing through holes to an
upper panel.
NOTE: If you create your own combination LCX
patch and splice panel on-site, remember to remove
knockout plugs at the top and bottom of LCX panels
before installing panels in racks. Knockouts can be
removed and flexible edge protectors can be
installed around the edge of holes after panels are
racked; however, it is easier before panels are
racked.
Avoid removing the knockouts on the top of the top-
most and bottom of the bottom-most LCX
panels. The knockout plugs also provide fire
abatement.
The hardware for connecting the patch splice together is not included when purchased separately.

2.5 Interconnecting & Cross-connecting with Special-Function Modules
Wavelength Division Multiplexing (WDM) and splitter modules can be used in LCX panels.
Figure 30 shows one way a 48-fiber IFC is spliced and then interconnected via splitters/WDMs to network
elements.
Three 3RU LCX configurable panels with dual, 1-to-3 splitters (or dual WDMs) are required for splitting/
de-multiplexing the 48 incoming fiber signals.
Dedicated LCX patch panels can be used to interconnect/cross-connect the split/de-multiplexed signals
with the network elements. In such case:
•Splitting 48 signals three ways requires a 4RU LCX patch panel with 144 adapters
•De-multiplexing 48 signals into two wavelengths requires a 4RU LCX patch panel with 96
adapters
Three, 3RU LCX Configurable Patch Panels
with eight, 1-to-3 dual splitters can be used
to terminate spliced strands from a
single 48-fiber LCX Fiber Splice Panel.
A single, factory-configured 4RU Fiber
Patch Panel can be used for centralized
patching of outputs from the splitters.

Chapter 3: Panel Installation
3.1 Installation Considerations
WARNING! To avoid eye damage or blindness, never look directly into fibers or connectors.
ADVERTENCIA! Para evitar leslones oculares o ceguera, nunca mire directamente a las fi bras o
conectores.
ATTENTION! Pour éviter toute lésion occulaire ou cécité, ne regardez jamais directement dans les
fibres ou dans les connecteurs.
ALERT! This product must be installed and maintained by qualified technicians.
ALERT! These instructions presume you have verified that the Telect equipment being installed is
compatible with the rest of the system, including power, ground, circuit protection, signal
characteristics, equipment from other vendors and local codes or ordinances.
3.1.1 Location & Space
LCX fiber panels adapt to standard 19-inch, 23-inch or ETSI racks with WECO, EIA or ETSI spacing and
nominal 3¼-in. extensions beyond the front rack flange.
Plan the input/output, upward/downward (cable feed) layout of each panel and its position in the rack
before beginning LCX panel installation. If you plan to pass fiber strands, cable and/or tubing through the
knocked-out holes in the tops and bottoms of the panels, the panels should be mounted in contiguous
vertical rack spaces.
3.1.2 Tools & Equipment
No special tools required.
3.1.3 Inspection
Please read and understand all instructions before starting installation. If you have questions, contact
Telect at [email protected] or call 1-509-926-6000.

3.2 Panel Installation Procedure (All Except 1RU)
Prepare, mount and insert modules and cable management rings
in all panels in a rack before cabling any panels in the rack.
1. If applicable, if you plan to pass fiber strands, cables and/or
tubing through the 1½-in. (38.1 mm) diameter holes in the
tops and bottoms of panels, see the notes below and then
knock out the applicable fire-abatement plugs covering these
holes (Fig. 31). Install flexible edge protectors, 110048-F01 (or
a standard grommet for 1½ in. holes) in place of plugs.
NOTE:
•Avoid removing fire-abatement plugs on the top of the top-
most and bottom of the bottom-most panel
•Plugs can be knocked out when panels are in place on the
rack; however, plug removal is easiest before racking
panels.
2. Install standard entry/exit split arcs and/or either optional
isolation hook kits, KIT-CMHOOK or optional entry/exit arc
kits, KIT-CMARC, at the front and/or rear corners of the panel.
•Installing standard split arcs: Slip the arc over the top
and/or bottom edges of the chassis at the entry/exit
corners. Refer to Figure 32.
NOTE: Two of the provided arcs are longer than the rest.
These should go on the bottom rear of the LCX chassis.
•Installing an isolation hook kit (purchased separately):
Follow these steps and refer to Figure 33.
i. Remove the split arc at the top and bottom of the
applicable corner entry/exit
ii. Use the two Phillips head machine screws
(screws with cross recessed heads) to secure the
hook mounting plate and flat backing plate to
either side of the panel sidewall
•Installing an optional arc kit: Follow these steps and refer
to Figure 34.
NOTE: Arcs are attached to the angle-shaped mounting
bracket using a thread-forming screw and an anti-rotation
boss. The bracket contains two sets of screws and boss
holes so that each arc can be mounted with the arrow-
shaped keeper flange pointing either up or down.
i. Remove the split arc at the top of the applicable
corner entry/exit. Leave the split arc at the bottom
in place, as shown in the illustration on the right.

ii. Use the three thread-forming Phillips head
screws (screws with cross-recessed
heads) to attach the arcs to the angle
bracket. Normally, the arrow-shaped
keeper flange of the top two arcs point
down and the bottom one points up. For
flange clearance, the middle and bottom
arcs must use a different set of screw and
boss holes.
iii. Use the two Phillips head machine screws
along with the flatbacking plate to secure
this arc assembly to the panel.
3. Mount each panel to the rack using four 12- to 24-
thread-forming mounting screws supplied, two per side
(Fig. 35).
4. Torque to 35 in.-lb. (4.29 N•m.). For one of the
mounting screws, if desired, include a ground lug and
star washer. (Use one ground lug with #14 AWG
stranded wire per chassis.)
5. Install adapter packs and/or special function modules in configurable LCX fiber patch panels. Figure
36 shows a six-adapter pack being installed in a 4RU LCX fiber configurable patch panel.
6. Push in quick-connect plungers at both ends of faceplate to lock pack or module in bulkhead.
7. Place a plastic cabling ring at each of the four corners of the chassis (Fig. 37-38). Rings can be
added and moved around later during cabling. The rings not only serve as corrals for fiber cable but
also as guideposts. Cables can be inserted in the split rings or routed around the rings.
NOTE: Each shelf of an LCX fiber patch/splice combination panel must be grounded separately.
