INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek Series 94882SL singlemode forty-eight channel video multiplexer with bi-directional multi-protocol data. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The 94882SL Series units operate as a transmitter / receiver pair for the digital transmission of forty-eight simultaneous NTSC or PAL video signals along with two channels of field configurable bi-directional data over one singlemode fiber optic cable. These data channels may be configured as RS485 data, RS422 data, RS232 data, or Manchester data. The RS485 channel may be configured for 2-wire (half duplex) or 4-wire (full duplex) with or without biasing. Switch selectable internal 120 ohm terminations are available for RS422 or RS485 data.

NOTE: This unit is shipped with Data Channel 1 and Data Channel 2 in the RS485 4-wire configuration. For other configurations, please refer to the DATA MODE section for changes to the default switch settings.

NOTE: This unit is shipped with data terminations off and data bias off for Data Channel 1 and Data Channel 2. For other configurations, please refer to the DATA TERMINATION / BIAS section for changes to the default switch settings.

The RT-94882SL transmitter accepts up to forty-eight video inputs in six groups containing eight videos and multiplexes each group into a high speed serial data stream. The first group’s serial data stream modulates a laser at 1510nm wavelength. The second group’s serial data stream modulates a laser at 1530nm wavelength. This pattern is repeated for group’s three through six using wavelengths 1550nm through 1610nm respectively. A Course Wave Division Multiplexer (CWDM) combines these six wavelengths, along with the forward data wavelength of 1490nm and the return data wavelength of 1470nm, onto a single optical output port for connection to the fiber transmission system. Correspondingly, the RR-94882SL receiver converts the optical signal to forty-eight independent video output signals and two forward data channels while transmitting the two return data channels.

The 94882SL Series product is designed to operate over an optical loss budget range of 0dB to 21dB on 9um singlemode fiber. Refer to the product specification sheet for additional performance data.

INSTALLATION

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.

RT-94882SL COMPONENTS

The RT-94882SL consists of the following components:

1) RT-980-1510 1) RT-980-1570 1) RT-482-1470/1490 1) SR-20

1) RT-980-1530 1) RT-980-1590 8) PCSC/UPC-0.3 1) PSR-2

1) RT-980-1550 1) RT-980-1610 1) MTX-CWDM-8 1) BPS-1 The individual 980 series video rack cards that make up the RT-94882SL are combined in a

rack mount configuration using the SR-20 subrack. Please refer to the instruction manuals for the SR-20 and the PSR-2 for information on the installation of the subrack with its power supply. The individual 980 series rack cards can slide into any of the open slots in the SR-20 subrack, however, the recommended configuration is shown below. This configuration starts with a blank panel next to the PSR-2 power supply followed by the RT-482-1470/1490 data card. The lowest wavelength video card, the RT-980-1510 continues the configuration which ends with the highest wavelength card, the RT-980-1610, at the left side of the rack. Following this configuration allows the fiber port on the back of the 980 series cards to best line up with its associated port on the CDWM unit. Use a small screwdriver to push and lock the ¼ turn fasteners into place. The Multi-Channel Digital Video CWDM that optically multiplexes the six video rack cards and one data rack card used in the RT-94882SL is labeled MTX-CWDM-8. It should be mounted directly below its corresponding SR-20 subrack with a ½ RU space between the two components. To maximize the performance and life of the system, installing a fan above the SR-20 subrack is recommended to pull air up across the RT-94882SL components.

RR-94882SL COMPONENTS

The RR-94882SL consists of the following components:

1) RR-980-1510 1) RR-980-1570 1) RR-482-1470/1490 1) SR-20

1) RR-980-1530 1) RR-980-1590 8) PCSC/UPC-0.3 1) PSR-2

1) RR-980-1550 1) RR-980-1610 1) MRX-CWDM-8 1) BPS-1 The 980 series video rack cards and the data rack card that make up the RR-94882SL are

installed in a manner similar to the RT-94882SL (see drawing below). The Multi-Channel Digital Video CWDM that optically demultiplexes the six video rack cards and the one data card used in the RR-94882SL is labeled MRX-CWDM-8. Mounting procedures and recommendations should follow those used for the RT-94882SL.

POWER SOURCE

Power to the 980 series and 482 series rack cards is supplied by the subrack. Please refer to the SR-20 and PSR-2 instructions for further details.

The CDWM unit is a passive device which does not require any power source.

POWER CONNECTION

Power is supplied to the individual 980 series and 482 series units via a four finger backplane connector. The individual components can be inserted into the subrack or removed from the subrack with power applied to the backplane. Please refer to the SR-20 and PSR-2 instructions for details.

The CDWM unit is a passive device which does not require any power connection.
