Fibre optic interconnecting devices and passive components performance standard - Non-connectorised single-mode bidirectional 1490 / 1550 nm downstream 1310 nm upstream WWDM devices for category C. Controlled environment algolia-search-ignore Shear strength is determined either

Shear strength is determined either by measuring the shearing force causing failure (direct shear tests) or by derivation from the measured compressive strength (unconfined or triaxial compression tests)

Fibre optic interconnecting devices and passive components performance standard - Non-connectorised single-mode bidirectional 1490 / 1550 nm downstream 1310 nm upstream WWDM devices for category C. Controlled environment algolia-search-ignore Shear strength is determined either1 Scope This part of IEC 61753 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 490 1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device must satisfy in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 617531. Annex B of this standard
