Is this a male-to-female or female-to-female type?

This is an adapter type (female-to-female) attenuator, designed to connect two FC/APC patch cables directly.

What is the difference between this Adapter Type and an In-line VOA?

The primary difference lies in their physical form and installation method: while an In-line VOA comes with fiber pigtails (typically 1 meter) and is designed to be spliced or integrated directly into a system's internal optical path, the Adapter Type VOA features a compact, pigtail-free design. It acts as a mechanical 'bridge' between two existing patch cords, making it the perfect space-saving solution for quick power adjustments on patch panels or ODF mountings without requiring additional splicing.

FC/APC Single Mode Adapter Type Variable Optical Attenuator

The FC/APC Single Mode Adapter Type Variable Optical Attenuator is a compact, plug-in optical attenuation solution designed for precise manual adjustment of optical power in single-mode fiber systems. Featuring an adapter-style (female-to-female) structure, it can be directly installed between two FC/APC connectors without additional fiber pigtails.

This attenuator offers a continuously adjustable attenuation range from 1 dB to 30 dB, enabling flexible signal control in testing, system balancing, and protection of sensitive optical components. The FC/APC interface ensures low back reflection and stable performance in high-precision optical networks.
