SC UPC Fixed Fiber Optic Attenuator, Single Mode Optical Attenuator 0dB to 30dB

Visão geral do produto

The Luleey SC UPC Fixed Fiber Optic Attenuator is a passive optical component designed to reduce optical signal power by a fixed attenuation value in single mode fiber networks. It is commonly used when the received optical power is too strong for the optical receiver, or when engineers need to balance link budgets during installation, testing, and maintenance.

This SC UPC Attenuator is suitable for FTTH, FTTX, CATV, telecom rooms, ODF systems, PON networks, fiber testing, optical transceivers, media converters, switches, routers, servers, storage devices, and optical network maintenance.

The SC/UPC connector uses an angled polish structure, making it suitable for low-reflection single mode optical systems. Compared with UPC connectors, UPC connectors are more commonly used in FTTH, CATV, PON, and optical distribution environments where return loss performance is important.

Luleey provides multiple fixed attenuation values from 0dB to 30dB, helping installers and network engineers select the proper signal reduction value for different optical link requirements.

Why Use an SC UPC Fiber Optic Attenuator?

A fiber optic attenuator is used when the optical signal power is too high for the receiving device. In fiber networks, too much optical power may overload the receiver and cause unstable links, device alarms, packet loss, or poor performance.

A fixed attenuator helps:

• Reduce excessive optical power
• Protect optical receivers
• Balance optical link budgets
• Prevent receiver overload
• Improve link stability
• Support fiber testing and troubleshooting
• Simulate fiber loss in lab environments
• Match optical power requirements between different devices

For FTTH, CATV, telecom, PON, and optical testing applications, the Luleey SC UPC Fixed Fiber Optic Attenuator is a practical passive component for optical power control.

SC APC vs SC UPC Attenuator

SC APC and SC UPC attenuators are not the same. They use different connector end-face structures and should not be mixed directly.

Choose SC/UPC when the connected fiber line, patch cable, adapter, ONU, OLT, splitter, or optical equipment also uses SC/UPC.

Choose SC/APC only when the connected equipment and patch cable are SC/UPC.

Do not directly connect APC and UPC end-faces together, because this may cause poor contact, higher insertion loss, higher reflection, and unstable optical performance.

How to Choose the Right Attenuation Value

The correct attenuation value depends on the optical receiver input range and the actual received optical power. Before choosing the dB value, measure the current optical power with an optical power meter.

The selected attenuator should reduce the received optical power into a safe and stable operating range.
