  • The high power polarization maintaining isolator (1310nm\/1550nm PM isolator) is customizable, and the above specifications are subject to change without notice.<\/li>\n
  • For device with connectors, IL is 0.3dB higher, RL is 5.0dB lower, ER is 2.0dB lower.<\/li>\n
  • Unless otherwise specified, the slow axis of the fiber is aligned with the key of the PM fiber connector.<\/li>\n
  • Slow axis working and fast axis blocked as standard, while operating on both the slow and fast axis available on request.<\/li>\n
  • Bare fiber should not support the weight of the connector. So that if any connectors needed, for the pigtail type it\u2019s better to choose the 900\u03bcm loose tube jacket instead of the 250\u03bcm bare fiber.<\/li>\n
  • For CW high-power optical interconnection, we recommend fusion splice without connectors.<\/li>\n
  • For product customization or special requirements, please contact Lfiber\u2019s sales department for availability.<\/li>\n<\/ul>\n

      A fiber optic component that transmits light in only one direction, thereby preventing reflected light from returning back to the source. It is built with PM Panda fibers and capable of maintaining a well-defined state of polarization (SOP) of the light. This polarization maintaining isolator (fiber-coupled PM isolator) can be single or double\/dual stage depending on the degree of required optical isolation of the propagating light. It\u2019s a good choice in many laser applications, since back-reflected light often have deleterious effects on the operating conditions of optical devices.<\/p>\n","protected":false},"featured_media":828,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":""},"product_brand":[],"product_cat":[66],"product_tag":[],"class_list":{"0":"post-821","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-pm-isolator-1310nm-or-1550nm","7":"desktop-align-center","8":"tablet-align-left","9":"mobile-align-left","11":"first","12":"instock","13":"shipping-taxable","14":"product-type-simple"},"_links":{"self":[{"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/product\/821","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/media\/828"}],"wp:attachment":[{"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/media?parent=821"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=821"},{"taxonomy":"product_cat","embeddable":true,"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=821"},{"taxonomy":"product_tag","embeddable":true,"href":"http:\/\/optiunik.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=821"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
