Patch cord apc connector

This ensures that focused beams of light are not incident on fragile parts of the connector or fiber, which can possibly cause damage. Always inspect the fiber end prior to connecting the fiber to an optical system.

The fiber end face should be clean and clear of dirt and other contaminants that can cause scattering of coupled light. Bare fiber should be cleaved prior to use and users should inspect the fiber end to ensure a good quality cleave is achieved.

If an optical fiber is to be spliced into the optical system, users should first verify that the splice is of good quality at a low optical power prior to high-power use.

Poor splice quality may increase light scattering at the splice interface, which can be a source of fiber damage. Users should use low power when aligning the system and optimizing coupling; this minimizes exposure of other parts of the fiber other than the core to light.

Damage from scattered light can occur if a high power beam is focused on the cladding, coating, or connector. Tips for Using Fiber at Higher Optical Power Optical fibers and fiber components should generally be operated within safe power level limits, but under ideal conditions very good optical alignment and very clean optical end faces , the power handling of a fiber component may be increased.

Users must verify the performance and stability of a fiber component within their system prior to increasing input or output power and follow all necessary safety and operation instructions. The tips below are useful suggestions when considering increasing optical power in an optical fiber or component.

Users should follow all appropriate guidelines to prepare and make a high-quality fiber splice. Poor splices can lead to scattering or regions of highly localized heat at the splice interface that can damage the fiber. After connecting the fiber or component, the system should be tested and aligned using a light source at low power. The system power can be ramped up slowly to the desired output power while periodically verifying all components are properly aligned and that coupling efficiency is not changing with respect to optical launch power.

Bend losses that result from sharply bending a fiber can cause light to leak from the fiber in the stressed area. When operating at high power, the localized heating that can occur when a large amount of light escapes a small localized area the stressed region can damage the fiber.

Avoid disturbing or accidently bending fibers during operation to minimize bend losses. Users should always choose the appropriate optical fiber for a given application. Step-index silica single mode fibers are normally not used for ultraviolet light or high-peak-power pulsed applications due to the high spatial power densities associated with these applications.

For SM operation near the cutoff wavelength, launch conditions need to be taken into consideration.

The wavelength range is the spectral region between the cutoff wavelength and the bend edge, in which the fiber transmits the TEM 00 mode with low attenuation. For this fiber, the bend edge wavelength is typically nm longer than the cut-off wavelength. MFD is nominal, calculated value, estimated at the operating wavelength s.

Attenuation is specified for unterminated fiber. Not all cable types are available in all lengths. For custom length cables see our Custom Cables page. Attenuation of SM fiber is highly dependent on wavelength.

Verification of the performance and reliability of fiber components in the system before operating at high power must be done by the user, as it is highly system dependent.

This is the estimated safe optical power density that can be incident on a fiber end face without damaging the fiber under most operating conditions.

The value of return loss for mated APC connectors in the field will typically be greater than dB. For a UPC connection, it is normally dB. For systems such as RF video, the APC connector is preferred because these particular systems are extremely sensitive to any back reflections from connectors within the network. In general, UPC connectors are deployed in transport systems designed for digital signal transport, while APC connectors are preferred for RF video signal transport.

APC connectors are also preferred where there are open ports at the other end of splitters, very typical in FTTP network designs. Cart 0.
