1. General
1.1 LC™Jumper Connectors
The LC Fiber Optic Simplex and Duplex Jumper Connectors can be used to terminate simplex
and duplex 1.6-mm MiniCordjumper cords. It is intended for use in Central Offices, Local Area
Networks (LANs), and in patch cords for Premises Distribution Systems such as SYSTIMAX®
Structured Cabling Systems. The connector can also be used in computer backplane
connections, computer peripheral interconnections, device terminations, and other applications
where quality, small-size, high-density, low-loss, and a low-cost infrastructure are required.
Note: In addition to the simplex and duplex LC jumper connectors for 1.6-mm MiniCord
jumper cords, a Behind-The-Wall (BTW) connector is offered for 0.9-mm buffered fiber.
Installation of the BTW connector is not covered in this customer information product
(CIP). The BTW connector can be used to terminate Outside Plant (OSP) cables as well
as building cables.
When installed on typical fiber, the following performance should be obtained:
Multimode
Insertion loss (avg.) = 0.1 dB
Return loss ≥30 dB
Singlemode
Insertion loss (avg.) = 0.2 dB
Return loss ≥50 dB

1.4 Ordering Information
Section 11 contains ordering information for LC connectors and kits.
2. Safety Precautions
• Safety glasses should be worn at all times while performing the installation procedures.
• Avoid skin contact with the epoxy.
• Place combustibles away from the curing oven when it is in operation. After the oven
has reached its operating temperature, the oven ports and heat tube assemblies are
extremely hot [266°F (130°C)]. Allow the oven and heat tube assemblies to cool before
handling or storing.
• Optical fibers may emit radiation if the far end is connected to a working laser or Light-
Emitting Diode (LED). Never view the fiber end of a cable or plug with the naked eye
or any optical instrument until absolute verification is established that the fiber is
disconnected from any laser or LED source.
3. Oven Preparation
3.1 Set Up Curing Oven
1. Place oven on a level surface and away from combustibles.
2. Connect the power cord to a power source (120 V 60 Hz AC for the 200A oven and 220 V 50
Hz AC for the 200Al international oven).
3. Locate the six heat tube assemblies (108 261 835) supplied with the D-182959 Upgrade Kit
(108 262 569).
4. Insert the heat tube assemblies into the heater ports.
Note: Be certain that the metal portion of each heat tube assembly is fully inserted into the
heater ports.
5. Push the ON/OFF switch to the ON position (lamp in switch illuminates).
Note: A READY lamp will illuminate when the oven reaches its operating temperature of
266°F (130°C).
Caution: After the oven reaches its operating temperature, the metal portion of the heat
tube assembly will be extremely HOT [266°F (130°C)]. Allow the oven and heat
tube assemblies to cool before handling and storing.

4. Cord Preparation
4.1 Assemble Connector Components
4.1.1 Simplex Applications on a Simplex Cord
1. Thread a cable support onto the simplex cord, narrow end first.
2. Thread a crimp sleeve onto the cord. The metal end of the crimp sleeve should be oriented
toward the end of the cord.
3. Repeat Steps 1 and 2 for the other end of the cord.
4.1.2 Singlemode Simplex Applications on a Duplex Cord
1. Split the jacket on the duplex cord into two separate cords at least 9 inches (230 mm) from
the end.
2. Thread a cable support onto each cord, narrow end first.
3. Determine the buffer color of each cord by looking into the end of the cordage. The duplex
cord should have a blue buffer and an orange buffer.
4. Thread a yellow crimp sleeve on the cord with the blue buffer and a white crimp sleeve on
the cord with the orange buffer. The metal end of the crimp sleeve should be oriented toward
the end of the cord.
5. Repeat Steps 1 through 4 for the other end of the cord.

4.1.3a Duplex Applications on a Duplex Cord (with Regular Duplex Yoke)
1. Split the jacket on the duplex cord into two separate cords at least 9 inches (230 mm) from
the end.
2. Thread a cable support onto each cord, narrow end first.
3. Determine the buffer color of each cord by looking at the end of the cordage. The duplex
cord should have a blue buffer and an orange buffer.
4. Locate the Bchannel opening on the duplex yoke.
5. At the first end, thread the cord with the blue buffer through the Bchannel opening.
6. Locate the Achannel opening on the duplex yoke.
7. Thread the cord with the orange buffer through the Achannel opening.
8. Place a yellow crimp sleeve on the cord with the blue buffer and a white crimp sleeve on the
cord with the orange buffer. The metal end of the crimp sleeves should be oriented toward
the end of the cord.
9. On the opposite end of the duplex cord, split the jacket into two separate cords at least 9
inches (230 mm) from the end.
10. Thread a cable support onto each cord, narrow end first.
11. Determine which cord has the blue buffer and which cord has the orange buffer.
12. Locate the Achannel opening on the duplex yoke.
13. Thread the cord with the blue buffer through the Achannel opening.
14. Locate the Bchannel opening on the duplex yoke.
15. Thread the cord with the orange buffer through the Bchannel opening.
16. Place a yellow crimp sleeve on the cord with the blue buffer and a white crimp sleeve on the
cord with the orange buffer. The metal end of the crimp sleeves should be oriented toward
the end of the cord.
