  • Page 6: Installation

    OSD9004 input is less than +3dBm or damage to the unit may occur. The OSD9003 can launch optical power as high as +7dBm. In situations where optical path attenuation is not high enough, a fixed optical attenuator must be used to reduce optical power at the OSD9004 receiver input to less than +3dBm.
  • Page 7 OPTICAL SYSTEMS DESIGN OSD9003/OSD9004 DRAWINGS AND DIMENSIONS The OSD9003/OSD9004 standalone module is designed to be mounted on an even surface and to be secured by means of M4 or smaller screws. 25.6 25.6 DETAIL A Ø8.5 R2.1 R2.1 DETAIL A 83.4...
  • Page 8 When an alarm occurs, the output goes into a high impedance state. When power to the OSD9003 unit is switched off or the laser current monitor indicates laser fail mode Pin 3 becomes open circuit. The unit’s monitoring circuit connects Pin3 to Pin2 (circuit ground) when there is no fault.
  • Page 9 OPTICAL SYSTEMS DESIGN 2.5.3 OSD9003/OSD9004 SWITCH SETTINGS FIGURE 4: OSD9003 SWITCH SETTINGS OSD9003 Settings In Manual Mode the RF attenuation is controlled by dip switches (SW1-SW5). Each toggle switch changes the Input RF attenuation level by 1,2,4,8 and 16dB respectively. Toggling the position on any switch is the sum of the attenuated amount ie switch 1 (16dB) and 3 (4dB) enabled will provide an attenuation of 20dB.
  • Page 10 RF output power manually or alternatively can be set to automatic gain control by setting switch 6 to the on position (up). In automatic gain control mode the unit maintains constant output level over the optical range of 15dB. DOC ID: 10111701 PAGE 10 OSD9003/OSD9004 OPERATOR MANUAL...
