Installation completed Review: Works Great, But Read the Instructions Here on desertcart! - I initially had the darnedest time with this widget. I had trouble getting the foam seal out, in, and especially out again when I wanted to move the splice to another cable. Then I read the directions here on desertcart, and life got vastly better. Be aware that the little fingers that hold the foam seal are usually tight enough that getting the foam out and then back in seems impossible, though it becomes very easy if you have some tool like a watchmaker's screwdriver at hand to use as a micro-pry-bar. (I used a knife, but that requires a lot of care lest you cut the foam.) Getting the foam back into the coupler's "fingers" takes some manipulation, but really isn't very hard once you get the hang of it. Anyway, the widget is great. Just do read the instructions here rather than doing silly things like I did. ;) ## Features - LC fibre optic waterproof coupler is suitable for extending fibre optic cable connections by connecting 2 short LC fiber optic cables together, thus protecting network components from moisture, oxidation and corrosion and enabling high quality connections. - This fibre optic duplex coupler allows for quick connection/disconnection, is waterproof to IP68, works effectively in harsh environments and uses cable assemblies efficiently, accepts 2x (0-4mm) OD cable - This LC fiber optic waterproof connector shell is made of nylon PA66, high performance ceramic conduit is safe and reliable, using silicone ring and rubber ring to seal the water-proof performance of the product - Widely used where fibre optic signal transmission is required, no tools and expertise are required for installation, plug and play, easy and fast - Note: After long-term use in a humid environment, it is necessary to regularly check the sealing of the sealing ring to prevent water from penetrating into the connector. If used in corrosive soil and humid environment, the shell will be more susceptible to corrosion. Also, do not immerse the connector in water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C5R82DY4 | | Best Sellers Rank | #188,251 in Electronics ( See Top 100 in Electronics ) #1,148 in Fiber Optic Cables | | Brand | PNGKNYOCN | | Brand Name | PNGKNYOCN | | Cable Type | Fiber Optic | | Color | Black | | Compatible Devices | Router, Switch, Server, Network Device | | Compatible Phone Models | No Compatible Phone Models | | Connectivity Technology | Optical | | Connector Gender | Female-to-Female | | Connector Type | Optical | | Customer Package Type | Flat Free Package | | Customer Reviews | 5.0 out of 5 stars 6 Reviews | | Included Components | NO | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Shape | Round | | Manufacturer | YOUCHENG | | Model | PNGKNYOCN | | Number of Items | 1 | | Number of Pins | 2 | | Other Special Features of the Product | Waterproof | | Outer Material | Nylon | | Part Number | 20230519006 | | Recommended Uses For Product | Fibre optic cable connection extension, protecting network components in harsh environments | | Special Feature | Waterproof | | Specification Met | Ip68 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** PNGKNYOCN - **Cable Type:** Fiber Optic - **Compatible Devices:** Router, Switch, Server, Network Device - **Connector Type:** Optical - **Special Feature:** Waterproof ## Images ![IP68 Waterproof Fiber Optical Coupler, LC to LC Duplex Fiber Optic Cable Outdoor Waterproof Connector for LC Fiber Optic Cable Extension - Image 1](https://m.media-amazon.com/images/I/51VrrrCZXiL.jpg) ![IP68 Waterproof Fiber Optical Coupler, LC to LC Duplex Fiber Optic Cable Outdoor Waterproof Connector for LC Fiber Optic Cable Extension - Image 2](https://m.media-amazon.com/images/I/81HpXf8FQVL.jpg) ![IP68 Waterproof Fiber Optical Coupler, LC to LC Duplex Fiber Optic Cable Outdoor Waterproof Connector for LC Fiber Optic Cable Extension - Image 3](https://m.media-amazon.com/images/I/61P9zmeNPBL.jpg) ![IP68 Waterproof Fiber Optical Coupler, LC to LC Duplex Fiber Optic Cable Outdoor Waterproof Connector for LC Fiber Optic Cable Extension - Image 4](https://m.media-amazon.com/images/I/61WPO0-r4OL.jpg) ![IP68 Waterproof Fiber Optical Coupler, LC to LC Duplex Fiber Optic Cable Outdoor Waterproof Connector for LC Fiber Optic Cable Extension - Image 5](https://m.media-amazon.com/images/I/81D+UIxVQdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great, But Read the Instructions Here on Amazon! *by D***H on June 29, 2025* I initially had the darnedest time with this widget.
