2.4 Cabling
The 6002/3/4 models are passive, unidirectional wavelength division multiplexers. Each module
allows simultaneous transmission of two to four optical signals over a single fiber pair.
2.4.1 Fiber Optic Cabling
Optical cabled devices transmit (Tx) and receive (Rx) channel-to-channel signals through local
and remote modules. All fiber optic cables should be properly connected using the Tx to Rx, or
Rx to Tx orientation. The diagram in Figure 4 shows the correct cable installation.
Note: When cables are not in use it is imperative to keep the connectors clean and protected.
Optical cable management is important to ensure proper cable installation and system operation.
Each fiber cable and connector must be labeled appropriately.
Note: Different applications may dictate that a change in the labeling convention of the fiber
optics is required – dependent upon the architecture of the customer's application.
2.4.2 Cleaning Fiber Optic Connectors
Use a lint-free alcohol pad from a fiber cleaning kit to clean the ferrule and the end-face surface
of the fiber coupler before installing any type of cable or connector.
The ferrules and end-face surfaces of optical components must be kept clean and free of all
contaminants. Use an appropriate lint-free alcohol pad, (or similar lint-free cloth saturated with
reagent grade Isopropyl alcohol) to clean the end-surfaces of your fiber coupling. You may also
use special swabs made specifically for cleaning fiber optic couplers.
Note: Optical components must be kept clean at all times. Attach protective dust covers to fiber
connectors or cable ends when they are not in use.
2.4.3 Connecting Fiber Optic Cables
Attach the required transmit and receive cables to the 6002/3/4 modules. The connectors on the
rack mount models are located on the front panel. The stand alone model has the connecting ports
on the rear panel.
Note: Use extreme care when installing or removing connectors so that damage is not incurred
to the fiber end-face surface, or to the connector housing.
Dirty optical connectors are a common source of link loss or attenuation problems, especially for
the single mode fiber (SMF). Connectors should be checked and cleaned whenever there is a
significant or unexplained light loss.
Note: To prevent contamination, install appropriate dust covers on all unused or disconnected
optical components. Always clean the optical connectors before connecting them.
