Products Description
SC fiber optic attenuator: Applied to SC fiber optic interfaces, it looks very similar to the RJ-45 interface, but the SC interface appears flatter. The obvious difference is the contacts inside. If it is 8 thin copper contacts, it is the RJ-45 interface, and if it is a copper column, it is the SC fiber optic interface.
Fiber optic attenuators are devices used to reduce the power of optical signals to a certain extent.
Optical attenuator is a device used to attenuate optical power, mainly used for measuring the indicators of fiber optic systems, signal attenuation in short distance communication systems, and system testing.
The fixed fiber optic attenuator is refined using standard high-precision dust orchids. Used in various fiber optic transmission lines, with high attenuation accuracy and stable and reliable performance. The performance characteristics are independent of wavelength changes and can achieve dual functions of adapters and attenuators. Attenuation accuracy, high additional loss, low application optical distribution frame optical fiber network system, low-speed optical fiber transmission system. Fixed fiber optic attenuators can be classified into flange type and male/female type by type, and can be classified into SC, ST, FC, LC, etc. by model.

FAQ
What are the steps to replace the optical attenuator?
1. Use a power meter to measure the optical output power of the fiber optic transmitter. Please remember that industry standards define the optical input power of transmitters and receivers for specific network standards. If you are testing a 100BASE-FX transceiver, you should use a 100BASE-FX transmitter, and the optical output power of the transmitter should be within the range specified in the manufacturer's data sheet.
2. Connect the transmitter to the receiver and verify its normal operation at the maximum optical output power provided by the transmitter. You need to test the receiver with the minimum optical input power that the receiver can accept, while still providing the best performance. To achieve this, you need to obtain the lowest optical input power value from the manufacturer's data sheet.
3. Calculate the required attenuation level for testing. For example, the optical output power of the transmitter is -17 dBm, and the minimum optical power level of the receiver is -33 dBm. The difference between them is 16 dB. You can use a 16 dB barrier attenuator at the input of the receiver and retest the receiver. If the receiver is still functioning properly, it is within the specification range.
