You should always match the test light source wavelength to the network requirements. While one refers to 850, 1300, or 1550nm routinely, actual source wavelength may vary. One long runs of fiber typical of WANs or long-distance networks, the difference becomes important.

Pure cylindrical forms crafted from precision milled anodised aluminium or pure brass. A custom-built glass lens that brings you a low glare light experience. Industry leading LED technology, delivering up to 1100 lumen. Its ability to rotate – up to 30° of tilt and 360° of rotation – along with its IP rating make it perfect for any type of room. Introducing a fixture that’s stunning in every way you look at it.

The appropriate resolution for a measurement should be chosen according to the test. Laboratory measurements of low-loss patch cables, connectors, and fiber splices can be made to 0.01dB resolution and an uncertainty of 0.05dB or less if great care is used in controlling the test conditions.

Invisible air supply and extraction, up to 50m³/h. Works for your bathroom. Works for your living room. Works for any other room.

Field measurements of absolute power are no better than the absolute calibration uncertainty, but relative power measurements can be made to 0.1dB. Cable plant loss is affected by not only the meter uncertainty, but also the characteristics of the test source, and may have an uncertainty of 0.5dB or more.

We work independent of any brand. Our light ventilation products are compatible with any ventilation system (DUCO, Renson, any other ventilation system). Our light ventilation products can be placed into any Ø125 valve adapter.

Made for thick plaster, adjustable from 12 to 33mm. Comes with a yellow plaster lid. The complementary connector makes it easy to add wires into your ventilation valve adapter.

Our Ø108 clt csc ring is the ideal trimless solution for cross laminated timber and cold stretch ceilings. The complementary connector makes it easy to add wires into your ventilation valve adapter.

Generally, multimode fiber is tested with LEDs at both 850nm and 1300nm and single mode fiber is tested with lasers at 1310nm and 1550nm. The test source will typically be a LED for multimode fiber unless the fiber is being used for Gigabit Ethernet or other high-speed networks that use laser sources. LEDs can be used to test single mode fibers less than 5000 meters long, while a laser should be used for long single mode fibers.

Lower cost field optical power meters usually have a resolution of 0.1dB, laboratory meters display 0.01dB, and a resolution of 0.001dB is available on a few specialized fiber optic power meters.

Optical power is usually measured in dBm, or decibels referenced to one milliwatt. This log scale is used because of the large dynamic range of fiber optic links, a range of 1000 or more. Some power levels may be given in microwatts, which many meters measure directly.

The fiber optic power meter is a special light meter that measures how much light is coming out of the end of the fiber optic cable. The power meter needs to be able to measure the light at the proper wavelength and over the appropriate power range. Most power meters used in datacom networks are designed to work at 850nm and 1300nn. Power levels are modest, in the range of –15 to –35dBm for multimode links, 0 to –40dBm for single mode links. Power meters generally can be adapted to a variety of connector styles such as SC, ST, FC, SMA, LC, MU, etc.

Our light ventilation valve is designed for air extraction of up to 50m³/h and air supply of up to 30m³/h. Just like most regular ventilation valves, a downward airflow isn’t suited for installation in or above comfort zones. So make sure to correctly position air supply valves in the room, not above seating areas for example. More information and capacity graphs on the technical sheet. Don’t hesitate to contact us to check your ventilation plan for advice.

Power meters measure average optical power, not peak power, so they are sensitive to the duty cycle of the data being transmitted. It is important to specify the test conditions for measuring the optical power of a transmitter or at a receiver in terms of the data transmitted. Most networks have a diagnostic test signal for just this purpose.

Our light ventilation valve recieves its power via the valve adapter. Use our prado connector (complementary with the Ø108 plaster ring) to connect the Ø16 preflex to the valve adapter. All light ventilation fixtures are IP65 rated so they can even be used in the shower. Watch the installation video to learn more about installation.

Optical power meters, like Digital Multimeters, come in a variety of types. The measurement uncertainty of practically all fiber optic power meters is the same, limited by the physical constrains of transferring standards with optical connectors. Most meters have an uncertainty of +/-5% or approximately 0.2dB, no matter what the resolution of the display may be.

The world’s first good looking ventilation valve. Made from precision milled, anodised aluminium. Works with Duco. Works with Renson. Works with every other ventilation system. Show what you want, hide what you need.

The test source is a portable version of the source that is used in the communication network attached to the fiber. It simulates the signal in the fiber for loss testing with a power meter, so the test source should match the wavelength and source type of the system source.

The fiber attenuation coefficient is a function of wavelength, so source spectral characteristics can be important. When testing long lengths of fiber, you may need to make corrections to nominal source wavelength losses.

Extract up to 50m³/h. Completely invisible and incredibly quiet. The installation ring fits in every Ø125 ventilation duct, a flow setting scale and rasterized adjustment positions allow easy and accurate adjustment. Simply twist the light to start tweaking. Light and ventilation valve are easily retractable, ideal for maintenance. An integrated lock prevents from accidentally modifying the air flow after installation. Introducing a ventilation valve that effortlessly works with every ventilation system. Works with DUCO, works with Renson, works with every other ventilation system.

Allows you to seamlessly integrate Ø108 fixtures into a concrete ceiling (50mm recessed). Requires a concrete installation box. A big advantage of our Ø108-118 concrete ring lies in its compatibility with a wide range of solutions. Scroll down to learn more.

The vertical part of the ventilation adapter (before the start of the turn) must be at least 74mm high for the plaster ring to be installed correctly. The connector can’t be placed in this zone. With most valve adapters, this means you need a total height of at least 105mm. Check the Ø108 plaster ring installation instruction or watch the installation video to learn more about installation.
