Features

LC^®/PC or LC^®/APC Connectors
- LC/APC Connectors do Not Come Pre-Angled
Smaller Ferrule and Housing Size than SC/PC Connectors
Spring-Loaded, Ø1.25 mm, Ceramic Ferrule
Strain Relief Boots for Ø900 µm or Ø3 mm (green boot only) Tubing and Connector Cap Included

These LC^®*/PC (Lucent Connector / Physical Contact) and LC/APC (Lucent Connector / Angled Physical Contact) connectors were developed to meet the need for smaller and easier-to-use fiber optic connectors. These connectors reduce space required on panels by 50% compared to SC/PC connectors.

The ferrules in the LC/APC connectors do not come pre-angled, users will need to polish the ferrule to 8° to use as LC/APC connectors. A blue boot is used to designate the LC/PC connector while a green boot is used to designate the LC/APC connectors. Packaged with a strain relief boot for either Ø900 µm or Ø3 mm (green boot only) tubing and a dust cap, these connectors each have a Ø1.25 mm, spring-loaded, ceramic ferrule. Thorlabs also offers loose ceramic LC/PC ferrules as well as splice-ready LC/PC connectors.

As an alternative to buying and assembling separate optical fiber, connectors, and furcation tubing, Thorlabs also offers custom pre-built patch cables using the connectors sold on this page, including LC/APC angled ferrules. See our Custom Fiber Patch Cable Configurator to place an order.

Let me question that how much attenuation loss should be considered for this LC/PC Connector 30126L9. If there's any applicable ITU recommendation, kindly share with me.

Thank you for reaching out to us at Thorlabs, attenuation and losses come from a variety of sources when working within an optical fiber system. We have some of the typical loss-specs listed on the product page. Others tend to be application-dependent. I have reached out to you directly with more information regarding your specific application.

Dust Cap

Zoom

The CAPL Dust Cap is for use with Ø1.25 mm fiber connector ferrules. Dirt on the fiber tip can cause permanent damage to the fiber connector, which can result in increased coupling losses or undesirable mode structure in the output light. To prevent damaging the connectorized fiber, clean it before each use and use a fiber connector cap to protect the end face of the connectorized fiber when it is not in use.
