The fiber-optic interface reduces susceptibility to conducted electrical noise present on metallic communication paths. Installation requires verification of optical path attenuation; where total fiber attenuation remains below 3 dB, an external 3 - 4 dB attenuator should be inserted to prevent optical receiver saturation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the SNT501-13 support direct electrical ESB bus extension without optical fiber?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The module is intended for optical transmission of ESB bus signals and is designed to operate with fiber-optic communication links.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum number of repeater stages supported?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The specification permits a maximum of two connecting stages within the optical ESB bus repeater network.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is additional optical attenuation sometimes required?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes.
