The rugged 907 Video / Data Multiplexer system provides transmission of multiple video and data channels through a single optical fiber. These low-power multiplexers are available in a compact PC / 104 form factor. Standalone motherboards feature three high quality video channels and six serial data channels. For more advanced requirements, expansion cards and media converters may be stacked on the motherboards to provide modular systems that can be easily configured for many applications.

Motherboards

Motherboards are supplied in diverse optical configurations from high power versions for demanding optical systems to low cost options using bidirectional (Bidi) transceivers.  Each motherboard can operate as a standalone multiplexer (mux) with three unidirectional video channels (remote to console) and six bidirectional serial data channels (4 x RS-232 and 2 x high-speed RS-485/422). Video channels support NTSC and PAL composite signals as well as S-video (Y/C) and RGB formats.  Data channels support NRZ data rates up to 2.5 Mbaud, or 120 kbaud when configured for RS-232.  Alternative motherboards include the 907V with six video channels and the 907Plus with four video channels and six data channels. Expansion cards and media converters are compatible with all motherboards.

Cards are supplied with a singlemode or multimode Wavelength Division Multiplexer (WDM) for operation over a single fiber or without a WDM for two fiber operation.  Cards may also be configured with Coarse Wavelength Division Multiplexer (CWDM) transceivers, which allow data from multiple 907s, media converters, and other products to be combined on the same optical fiber.

Expansion Cards

Four to six expansion cards may be stacked on a motherboard using the PC/104 connectors for power and signals.  Each expansion card provides additional analog or digital formats or an increased number of serial data channels.  The 907-AIB expansion card allows standard AIB (Adaptable Interface Board) plug-in modules from the 903 system to be employed in 907 solutions as well.  Expansion cards may also be stacked on 907V or 907Plus motherboards.

Media Converter Cards

Media Converter Cards provide optical transmission of high speed data signals (20-1500 Mbps), such as Fast Ethernet, ECL/PECL for multi-beam sonar uplinks, IEE-1394 for digital cameras, and digital high definition video (SMPTE-292).  Media Converters may be deployed as standalone cards running on their own fiber or as CWDM versions that are optically multiplexed on the same fiber as the 907 motherboard.  Two CWDM wavelengths may be added to the standard 1310 / 1550 nm 907 link without changing the motherboard, thus providing an easy upgrade path.  With CWDM transceivers on all cards, up to sixteen wavelengths may be combined on a single fiber.  USB and Gigabit Ethernet switch solutions are also available.

AIB Plug-In Modules

Adaptable Interface Board (AIB) plug-in modules are used with the 907-AIB adapter expansion card to convert one of the motherboard data channels to a different data format.  Each adapter card provides two independent AIB sockets.  AIB plug-ins support standard serial data interfaces (RS-232/485/422), hydrophone and other audio signals, various digital and analog sonar telemetry, and control networks, such as CAN and Profibus.
