  • Page 19: Media Converters

    Stacking units have long pins on the PC/104 connector so that they can be stacked on top of other cards, typically a 907 motherboard with expansion cards. Usually stacking units have CWDM wavelength transceivers so that their optical signals can be combined with other cards in the stack on a common fiber.

    Kongsberg EM2000 and EM3000. The 907-ECL card can be ordered as a standalone card (built with short PC/104 connector pins and a short optical jumper from the SFP transceiver to the optical ST-ST bushing) or as a CWDM stacking version, for integration with a 907 multiplexer or other devices.

  • Page 23: 907-Hdv (Hd-Sdi)

    Config. Dwg. 907-2012-00 The 907-HDV (HD-SDI) media converter is based on the same printed circuit board assembly as the 907- ECL, but using an SFP transceiver with a higher data rate to support the 1.5 Gbaud signals. At the remote (subsea) end, the camera signal is input at SMB jack J1, as shown in Figure 4-7. At the console end, the HD-SDI monitor or processing equipment is attached to jack J3.

  • Page 24: 907-Gbe (Gigabit Ethernet)

    Config. Dwg. 907-2021-00 The 907-GBE (Gigabit Ethernet) media converter shown in Figure 4-8 is used to convert a single channel of 10/100/1000 Mbps Ethernet data into optical format at the remote end and vice-versa at the console end. Regardless of the input data rate, the optical link always runs at 1000 Mbps. Jumbo frames are supported.

  • Page 25: 907-Gbes (Quad Gigabit Ethernet Switch)

    In this way, the 907-GBES card can behave like a 907 motherboard or a 907 media converter. Each 907-GBES is fuse limited to 2.0 A of on-board current draw and 5.0 A of total current draw from the 907-GBES and all stacked cards.

  • Page 26: Expansion Cards

    When one of the six data ports is assigned to a stacked expansion card, the corresponding on- board i/o circuits on the motherboard are disabled to avoid a conflict. For example, if a 907-485 card is assigned to data port 5, then the channel 5 RS-485/422 channel on the 907 card itself is disabled while the expansion card overrides it.

    Installation and Operation Mounting The model 907 multiplexing cards all come in the standard PC/104 form factor of 3.55 × 3.775 inches (90.17 × 95.89 mm). The cards are outfitted with a PC/104 keyed connector to provide backplane connectivity between multiple cards assembled in a vertical stack. Note that this connector, as used by the Model 907 system, has a proprietary pin-out.

  • Page 53: Power

    All Model 907 cards which require power require a regulated +5 VDC. The tolerance varies from card to card, but is typically (+/- 5 to 10%). Current draw varies from card to card, and the total current draw for a stack (if drawn from the motherboard) must be calculated to ensure it does not exceed the fuse rating of the motherboard.

  • Page 54: Maintenance

    EX-L to carefully wipe any dirt off the face of the ceramic ferrules prior to making a connection. Always replace dust caps on the Model 907 fiber optic bushings when removing connectors. If bushings are left open, they should be cleared of dust with compressed air prior to reconnection. Fiber jumpers and pigtails should be periodically inspected for damage, such as nicks in the jackets or excessive bends.
