  • How to intake air for cold aisle server racks

    How to intake air for cold aisle server racks

    Arrange server racks in a hot aisle/cold aisle configuration. Most equipment manufactured today is designed to draw in air through the front and exhaust it out the rear. Cold aisle containment (CAC) is a proven data center cooling strategy that creates physical barriers around cold air supply zones, preventing contamination from hot exhaust air and eliminating the energy-wasting effects of air mixing. Pick the Low-Hanging Fruit The first step to take is implementing certain basic measures to increase cooling efficiency, save money and improve your data center's carbon. Cold air is directed to the front of server racks, while hot air released from the back is removed. When the heat isn't managed well, it can slow down your servers, cause shutdowns, or even damage your equipment. Over time, this can lead to costly problems.

  • Distance between cable tray and air duct

    Distance between cable tray and air duct

    The horizontal safety distance between cable trays and ventilation ducts should generally be no less than 100 mm. In some projects, especially where airflow is critical, this distance may be increased to 150 mm or more. What is the required separation distance for them to be considered separate obstructions where we can omit sprinklers below, as long as they are 24" away (horizontal). Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. I have 2 questions: Why there is a problem with “Point Z” node when I'm trying to connect it to “Element. Get location”? Are there any other ways to get Z coordinates of every cable trays. Can't tell you for Canada, but in the US (NEC) there is no distance requirement (assuming no splicing / boxes or special conditions), just the common sense of being able get your hands in there to dress the cables in the tray. Not all cable ties are created equal. The information listed below can be.

  • Reasons why the air port of the optical splitter cannot be used

    Reasons why the air port of the optical splitter cannot be used

    A more common cause is poor field termination that results in air gaps and high insertion loss or scratches, defects and contamination on the end face of the connector. Fiber optic splitters distribute optical power from one input fiber to multiple output fibers through either fused biconical taper (FBT) coupling or planar lightwave circuit (PLC) waveguide structures. Their performance depends on optical symmetry, waveguide integrity, and mechanical stability of. Optical splitters in the outside plant (OSP) are used mostly in passive optical networks (PONs) for fiber-to-the-user (FTTx) networks, and are often overlooked as failure points. You can read more about their use in FTTH PONs and passive OLANs in the FOA Guide. The fiber optic. Or it could be caused by the quality of the connector itself, such as poor end-face geometry that doesn't pass the parameters defined by IEC PAS 61755-3 standards, including angle of the polish, fiber height, radius of curvature or apex offset. I'm confident that's the right answer. I know Splitter is used for connecting ports, but I'm not sure about the specific.

  • Air bubbles in the fiber optic cable connector

    Air bubbles in the fiber optic cable connector

    There are bubbles or cracks in the joints during welding This situation may be due to poor cutting of the optical fiber, such as inclined end faces, burrs, or unclean end faces. Perhaps one of the most maddening things about a mixed material is entrained bubbles. You want to stab them, push them and blow on them. It is necessary to clean the optical fibers before performing fusion splicing operations; another case is that the.
