Designed for panel or rack mounting, the shuttered design protects fiber ends from dust, ensuring reliable, high-performance multimode fiber connectivity in demanding environments. ## Description A great solution when you need to join two standard multimode duplex LC fiber patch cables together. The coupler is panel-mountable so you can use it where all your connections are accessible. The shuttered door prevents dust and debris from entering between cable swaps. The aqua color is indicative of OM3 and OM4 Aqua multimode fiber which is 50/125 laser optimised fiber. ## Features - ✅ Enjoy great quality, plus savings when purchasing this bulk pack of twelve (6) aqua multimode shuttered couplers. These are flanged couplers, which mean they can be used for panel mounting or also installed into our wall mount and rackmount fiber chassis units. - ✅ These couplers achieve ultra-low signal loss due to the ceramic inserts, which create a perfect fit and alignment of your LC fiber jumpers. - ✅ Our CableRack optical couplers have a wide operating temperature range of -20°C to +70°C, which means they can be deployed in typically unsuitable conditions. - ✅ LC fiber connectors are the most popular type of fiber connector being used today. LC feature a snap-lock type mechanism for making secure connections. - ✅ Multimode LC couplers may come in either teal color (as shown here) or a beige color. Either will work fine for OM5, OM4, OM3, OM2, and OM1 type fiber connections. ## Product Details - **Brand:** CableRack - **Connector Type:** Optical - **Cable Type:** Fiber Optic - **Color:** SHUT-MM6 - **Connector Gender:** Male-to-Male ## Images ![CableRack LC to LC OM3/OM4 Multimode Duplex Shuttered Fiber Coupler Aqua (6 Pack) - Image 1](https://m.media-amazon.com/images/I/61eLeWU1euS.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Small box, great for residential install *by I***P on Reviewed in the United States on May 1, 2019* I decided to pull fiber to remote parts of my home over running copper to be a bit more future proof. I had a terrible time finding a small box that would hold some excess fiber length as well as held LC-LC couplers, most were huge or needed to be rack mounted. I needed something compact I could mount on the side of my 6U server rack as well as something small to put on the wall in the remote sections of my home. This was the smallest I could find and it fits the bill perfectly. I imagine if you actually populated all 12 couplers it would be a bit of a tight squeeze in there, I only have 2 LC-LC couplers in the one at my server rack and it is starting to feel cramped. It comes with a lot of screws, tie downs and labels that aren't shown in the photos. It also comes with what appear to be heat shrink mechanical fiber splices if you are into that, but I didn't use them. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars its okay *by A***F on Reviewed in the United States on July 19, 2019* came with tons of accessories, not sure what they all were for but it's whatever ### ⭐⭐⭐⭐ 4.0 out of 5 stars Only 1 set of clamps on a 24Pair Panel. *by P***E on Reviewed in the United States on September 23, 2019* Good panels, only negative is it comes with 1 set of clamp for a panel with 48 cables or 24 pairs. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/176933527-cablerack-lc-to-lc-om3-om4-multimode-duplex-shuttered-fiber](https://www.desertcart.us/products/176933527-cablerack-lc-to-lc-om3-om4-multimode-duplex-shuttered-fiber) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-27*
