Introduction to the Fiber Optic Modem General Overview The Fiber Optic Modem is used to simplify field wiring and increase transmission distances by converting system copper-wired interfaces to fiber optic connections. It has field wiring connections for the Digital Audio Riser, Analog Audio Risers, RUI, and 4120 Network. A Modem pair replaces copper wiring between any two points including node-to-node, node-to-transponder, and transponder-to-transponder.
Introduction to the Fiber Optic Modem, Continued Definitions and X-link (continued): X-link connections are only required in Class A Analog Audio and Class A Terms RUI configurations. They are not required for the Digital Audio Riser interface, a Network interface, or for any other Class B configuration. Where required, the x-link connection maintains Class A supervision even though the remote side of the fiber link is electrically isolated.

It is either installed in the same manner as other standard panel 4-inch (102 mm) X 11-inch (279 mm) option cards (except that there is no PDI connection), or mounted using the mounting plate in the 4100 or any other close-nippled cabinet.
Mounting, Continued Mounting The Remote Expansion Cabinet (4190-9021, -9022, -9024, -9025) comes supplied with a Fiber Instructions Optic Modem Left-Port Assembly (4100-6072, -6074) and all necessary mounting hardware. Other boards like the Audio Expansion Board (4100-9842) are optional. To mount the modem in a Remote Expansion Cabinet with selected board options, refer to Figure 4.

Mounting, Continued Mounting To add a fiber modem audio expansion board to a 4100, see Figure 5. When mounting in any Instructions other cabinet, attach mounting plate to enclosure using self-tapping screws or equivalent. Mount the bracket first before mounting the modem and expansion board to the bracket. No standoffs are required.
Wiring Overview All Modem wiring is supervised and power-limited. The following Modem wiring must be within a system box or close-nippled to a system box: • Digital Audio Riser • 24V Card Power • 4120 Network Left Port • Analog Audio Risers •...
Wiring, Continued 4120 Network Wiring These wiring specifications apply to the Modem’s 4120 Network Right Port only (the Left Port Specifications must be internal or use close-nippled wiring): The distances listed below allow for the introduction of two lightning suppressors (TEPG Part# 2081-9027) into the communication line for installations where the wiring leaves the building.

Wiring, Continued Enhanced Analog EAA Combinational System Audio (EAA) Riser Wiring In some analog audio systems, more than six modem pairs might be required (therefore requiring Specifications EAA usage), but the topology will not allow for all modem-to-modem connections to be close nippled.
Wiring, Continued Digital Audio Riser These wiring specifications apply to the Modem’s Digital Audio Riser Wiring. Specifications The Digital Audio Riser (DAR) wiring is always within a system box or close-nippled to a system box. The DAR connection is always either to a Digital Audio Controller or a Digital Audio Riser Interface card.

Testing and Troubleshooting General Use this section as an aid in testing and troubleshooting a fiber modem pair installation. It should be noted that a fiber fault can cause a trouble on all connected media. A fiber fault must be resolved before any further troubleshooting or testing can be performed.
Testing and Troubleshooting, Continued The Modem has LED indicators as shown in Table 12. Refer to Figure 1 for LED locations. LED Indications Table 12. LED Indications Reference Function Details LED1 AAR1 FAULT Indicates a fault condition on Analog Audio Riser Channel 1. LED2 AAR2 FAULT Indicates a fault condition on Analog Audio Riser Channel 2.
Testing and Troubleshooting, Continued Analog Audio If the analog audio interface is not operating properly, verify the following: 1. The analog audio switches are properly set. 2. A good quality voltmeter can be used to measure the riser’s RMS voltage on the panel side loop, and then be re-measured on isolated loops to determine what modem pair could be causing a fault.
Testing and Troubleshooting, Continued Testing Circuit Use the procedures in the Table 13 to confirm that all interfaces (that are in use) are supervised for Supervision opens, shorts, and grounds. The left two columns indicate the interface/test method while the right column indicates the system response.
