    Division Multiplexing). CWDM systems support 4 to 16 wavelengths; DWDM systems support 16 or more wavelengths. Both CWDM and DWDM enable the combination of two or more FMBs, plus other media converter cards, on a single optical fiber, allowing considerable expansion of the Model 903 video and data channel capacity.

  • Page 15: Figure 2.3-2: Model 903 Fiber Optic Transmission System Expanded

    The media converter card uses 1471 nm and 1491 nm wavelengths and the FMB-X-2.5 card uses 1310 nm and 1550 nm wavelengths. Note that the 903 system continues operating on a single fiber (second fiber is optional). Refer to section 6.0 for more information about the media converter cards available for Model 903 systems.

    903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version Because of the high bandwidth of the HD-SDI signal, any external cabling and connectorization must adhere to proper RF practices. For example, 75-ohm cabling and connectors should be used throughout the entire link. Any connectors or cables with the wrong impedance, for example with straight wired pins and/or no shielding, will cause reflections and signal degradation.
