Optical Fiber Attenuator SC/APC(F) to SC/APC(M) 3 dB No name RB08823 single-mode

Inline optical fiber attenuator with SC/APC female to SC/APC male connectors, providing 3 dB attenuation for single-mode fiber links. This passive device is intended to reduce optical power levels in telecom, CATV and laboratory test environments. It is compatible with APC-terminated single-mode patchcords and adapters, and is designed to be inserted directly into an optical path to lower signal strength without converting formats or affecting fiber alignment.

Advantages

The attenuator offers a fixed 3 dB attenuation value that provides predictable reduction of optical power. Its SC/APC female-to-male connector arrangement ensures low back-reflection thanks to angled physical contact termination. As a passive inline component, it requires no power or configuration and can be used immediately in existing single-mode fiber assemblies. The compact form factor supports simple insertion into patch panels and test setups while maintaining stable insertion loss characteristics.

Suitable for

• Balancing link budgets in single-mode telecom and CATV systems
• Reducing optical power to protect sensitive receivers
• Creating controlled power conditions for fiber optic testing and measurements
• Temporary attenuation in lab benches and field test rigs

Key specifications

• Attenuation: 3 dB (fixed)
• Fiber type: Single-mode (SM)
• Input connector: SC/APC female
• Output connector: SC/APC male
• Connector polish: Angled Physical Contact (APC) for reduced back-reflection
• Device type: Inline passive optical attenuator
• Typical applications: Telecom, CATV, optical test and measurement

How to use

Insert the SC/APC male end of the attenuator into the corresponding SC/APC female adapter or equipment port, and connect the incoming fiber patchcord to the SC/APC female end of the attenuator. Ensure connectors are clean and free of dust before mating to avoid increased insertion loss or damage. Use standard fiber handling practices: avoid sharp bends, maintain proper strain relief, and avoid twisting. The attenuator provides a fixed 3 dB reduction when placed in the optical path; no configuration is required.

Usage recommendations

Prior to installation, inspect and clean APC connector endfaces with appropriate fiber cleaning tools. Avoid exposing the attenuator to mechanical shock or excessive pulling force. For precise power control during testing, verify attenuation effect with an optical power meter after installation. Store in a dry, dust-free environment when not in use.
