ST Attenuator
Fiber optic attenuators are devices designed to reduce (attenuate) the strength of an optical signal within a fiber optic network. They are typically used when the incoming signal is too strong and may overload the receiver. This can occur due to mismatched transmitters and receivers (such as transceivers or media converters) or when media converters are specified for longer transmission distances than required.
Attenuators are also valuable in testing environments, where the signal strength can be gradually reduced (increasing dB attenuation) to simulate performance limits and determine the network’s safety margin.
Our attenuators are manufactured with high-quality doped fiber to ensure precise attenuation. Single-mode attenuators operate within a 1250–1600 nm wavelength range, covering the common 1310 nm and 1550 nm bands. They support a maximum transmission power of 1 watt.
We stock attenuators compatible with connector types including ST, SC, SC/APC, FC, FC/APC, LC, LC/APC, and MU. Values range from 1 dB to 25 dB, with custom options available upon request.
While attenuators are most commonly used in single-mode networks—where stronger lasers are employed for long-distance transmission—we also supply multimode attenuators (custom order) in 50/125 and 62.5/125 fiber sizes. Please note, custom multimode orders may require a minimum quantity of 50 units and a lead time of 2–4 weeks.
