LTX Patch and Splice Panel

Installation Guide

2.3 Installation Guidelines

Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

2.4 Location and Space

The LTX patch and splice panel requires space in the front and rear for access to patching, splicing and cabling. Leave as much side clearance for tray and panel removal and worker access as required by your application or local regulations. Plan the input/output, upward/downward (cable feed) layout of each panel and its position in the rack before beginning LTX panel installation.

LTX panels adapt to standard 19" or 23" ETSI racks with EIA, ETSI and WECO spacing and nominal 3¼" extensions beyond the front rack ange.

2.5 Tools and Equipment

No special tools required.

Chapter 4: LTX Panel Cable and Fiber Installation and Routing

WARNING! To avoid eye damage or blindness, never look directly into bers or connectors.

CAUTION! Do not connect bers to the adapters before all pigtail bers have been installed and spliced

at the splice tray.

CAUTION! Wear safety glasses while working with exposed ber optic ber. Do not touch eyes while working with ber optic bers.

LTX patch and splice panels can be used to either interconnect or cross-connect Network Elements (NE). The panels are typically used to interconnect IF (IntraFacility) splices from the LTX panel to network elements, to interconnect one system of network elements to another, as in a demarcation, or to cross-connect network elements within the same system.

Fiber installation involves splicing, patching and storage using LTX patch and splice panels. Splicing begins with installation of the IntraFacility Cable (IFC) at the rear of the LTX Panel. Each IFC ribbon ber contains 12 optic bers. Each LTX splice tray handles up to 36 splices (three IFC ber ribbons).

The IFC routes to the LTX panel from above or below and is clamped at the side of the LTX panel with a cable clamp that holds it in position. Protected ribbon bers then route around splice trays in the slack storage area of the LTX panel. Extra ribbon should be measured out and routed through the panel to provide for splicing requirements.

In the rear of the LTX panel and at the front of the splice trays, cables are clamped and unprotected ber ribbons are measured out and routed through the splice tray to splice sleeve holders.

At the rear of the LTX panel, pigtail ber strands route from connectors that attach to adapters with ber jumpers at the front of the LTX panel. The pigtail bers route into the splice tray at the corner opposite to where the incoming IFC ribbon bers route into the tray.

The loose ribbon and pigtail ber strands are then spliced (interconnected) with resulting splices placed into splice sleeve holders in the center of the splice tray.

4.1 Cable Installation and Routing

4.1.1 IFC Cable Installation and Routing

The IntraFacility Cable (IFC) is brought in from above or below the LTX patch and splice panel.

The IFC is clamped to the cable clamp mounted on the top rear corner of the LTX panel. Protected 12-strand ber ribbons route from the cable into the LTX panel through the slack storage area. Routing spools protect splice trays from routed cables. Cables can be secured in the panel with velcro bands that attach to tie down slots on the tray platform and along the sides and top of the LTX panel.

At the splice tray, 12-strand ribbon bers are broken out of the protected cabling and route through the tray for splicing.

LTX Patch and Splice Panel

Installation Guide

Refer to Figure 4-5, Figure 4-5-1 & 4-5-2 for this procedure.

Fiber jumpers enter the LTX patch and splice panel from front corners and attach to adapters following the number scheme designated on the designation label mounted on the front door.

After connectors with pigtail bers have been installed and bers have been spliced:

1. Locate adapter designation number on the designation card located on the front door of the LTX panel. Record designation information.

2. Remove protective dust cap from the patch plate adapter port for the ber jumper being installed.

NOTE: To protect bers, work with one ber jumper at a time. Only remove the dust cap for the ber jumper being installed.

3. Clean adapter port with oil free “canned” compressed air to remove any dust that has accummulated there.

4. Remove the protective cover from the ber jumper by pulling it straight out.

5. Inspect the end of the ber jumper for any dust or debris. If needed, clean the ber with lint wipes and a commercial solution formulated for cleaning ber surfaces or a reagent-grade ethyl alcohol to remove particles.

6. Use a second dry wipe to dry the ber.

7. Inspect again to ensure ber end is clean; repeat Steps 5 - 6 if needed.

NOTE: After conrming the ber jumper end is clean, do not wipe the ber or allow it to touch anything before installing it in the adapter.

8. Insert the clean, dry ber into the adapter port.

9. Repeat Steps 1 - 8 to install remaining ber jumpers to adapters in the patch plate.

Chapter 5: Service

5.1 Owner Maintenance

The Telect LTX patch and splice panels do not require any preventative maintenance. If equipment is not working properly, contact technical support and be advised of the following warning/caution/alert.

WARNING! To avoid eye damage or blindness, never look directly into bers or connections.

CAUTION! Wear safety glasses while working with exposed ber optic ber. Do not touch eyes while working with ber optic bers.

ALERT! This product must be installed and maintained by qualied technicians.

5.1.1 High Insertion Loss and the Importance of Cleaning Connectors and Adapters

The major causes for poor performance (high insertion loss) are:

• Attenuation due to too sharp or too many close radius bends in the fiber cable

• Loose connections

• Dirty connectors or adapters

If you experience insertion loss greater than 2.5 dB, check for sharp bends and loose connections. Clean all polished ferrules on pigtails and both ends of the patch cord or jumper.

Though Telect includes dust caps with all adapters and connectors, it is not always possible to ensure that ber ferrules stay clean. If you need to clean connectors and adapters, Telect recommends a commercially available system or solution. Special formulation for cleaning ber ferrules allows the commercial solvent to stay liquid long enough to dissolve impurities quickly and thoroughly, yet evaporate quickly after wiping dry. Always allow the ferrules to air dry thoroughly before reconnecting. “Canned air” can be used to clean away debris initially, but do not use an aerosol after cleaning polished surfaces. Most aerosols contain contaminants.

If a commercial solution is not available, a reagent-grade ethyl alcohol, nominally USP > 99% can be used, available at pharmacies.

Remove both connectors from the adapter:

1. Blow compressed gas through the adapter.

2. Moisten a lint-free wipe with the ethyl alcohol.

3. Wipe completely around the ferrule of the connector twice. Repeat with a dry wipe.

4. Moisten the center area of a third wipe and pass the face of the ferrule from the moistened area outward toward the dry area.

5. Repeat Step 4.

6. Allow ferrule to air dry. After completing this step, do not wipe the ferrule or allow it to touch anything before inserting the ferrule into the adapter. Do not cover with a dust cap.

7. Insert the connector into the adapter.

8. Repeat Steps 1 through 7 for each connector.
