Nothing to source and nothing to match. The cage is a standard SFP and the module is hot-swappable if the run changes. - AUTO-SENSING COPPER: 10, 100 AND 1000 MBIT - The RJ45 port negotiates 10Base-T, 100Base-TX and 1000Base-T automatically against whatever you plug in - a switch, a camera, an NVR, a router or a laptop - with auto MDI/MDI-X so a crossover cable is never needed. IEEE 802.3 / 802.3u / 802.3z / 802.3ab. - DUAL-SPEED FIBER, SET ON THE DIP SWITCH - Select 1000Base-LX (default) or 100Base-LX on the rear DIP block, so the converter drops into an existing 100 Mbit fiber plant as easily as a gigabit one. The same block carries LFP on/off, broadcast storm control, and forced speed on both the fiber and the copper port. - LLF AND JUMBO FRAMES - LINK FAULT PASS-THROUGH THAT ACTUALLY TELLS YOU - With LFP enabled, a break on the fiber side drops the copper link too, so the switch at the far end sees the fault instead of holding a dead port up. Jumbo frame support keeps end-to-end TCP throughput intact on storage and backup traffic. - WHAT YOU GET: - Converter, the 1310 nm LC SFP module already fitted, 5 V AC/DC power adapter, a Cat6 patch cable, wall-mount ears and a cable clip. Everything needed for one end of the link. Most converters at this size ship the unit and a power brick, and leave the patch cable to you. - DESKTOP OR WALL, RUNS COOL, 0 TO 70 C - 94 x 70.5 x 26.5 mm, fanless, 5 V DC from the included 100-240 VAC adapter. Rated 0 to 70 C (32 to 158 F), wider than most indoor converters. LEDs for Power, Link/Activity, Full-Duplex and Speed give per-port state at a glance. Mounts flat on a desk or on a wall with the ears supplied. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CXRL34L | | Best Sellers Rank | #48 in Computer Networking Transceivers | | Customer Reviews | 4.7 4.7 out of 5 stars (108) | | Date First Available | May 8, 2018 | | Item Weight | 14.1 ounces | | Item model number | AN-UM-SMC-AS-J + SM-SFP-kit | | Manufacturer | AD-net Technology., CO LTD | | Product Dimensions | 3.7 x 2.76 x 1.04 inches | ## Images ![LC Single Mode Gigabit 20km (12.24 mi) Built-In Fiber Module Media Converter - Image 1](https://m.media-amazon.com/images/I/61d9RTVUhrL.jpg) ## Questions & Answers **Q: What fiber patch cord should I choose for this converter?** A: Use a duplex LC-LC single-mode UPC (BLUE) patch cord (9/125μm). The included SFP runs at 1310nm. Avoid APC (GREEN) connectors, as they are not compatible. If needed, you can swap the SFP for multimode or other options. **Q: I plan to use it as a standalone unit – what should I watch for?** A: This converter cannot replace ISP ONTs (e.g., FiOS, GPON). It works only with standard Ethernet-to-fiber links. Ensure the wavelength matches on both ends (e.g., 1310nm TX - 1310nm RX) and use a compatible LC UPC patch cord **Q: What is the most common fault if the converter does not come up?** A: The most common issue is TX/RX mismatch—swap the RX and TX fibers at one side. If using it standalone, ensure the wavelengths match on both ends (e.g., 1310nm TX - 1310nm RX). Also check if fiber module speeds match - i.e. 100FX or 1000FX **Q: Can I use this as a replacement for Verizon FiOS, Google Fiber, or other ISP fiber services CPE?** A: No, this cannot replace ISP ONTs like Verizon FiOS, Google Fiber, AT&T Fiber, or CenturyLink. These providers use GPON/XGS-PON, which requires their own ONT. This converter works only for standard Ethernet-to-fiber extensions, not ISP connections. **Q: Can I use different SFP modules, can I replace module?** A: Yes! The SFP slot supports all types of fiber modules, including single-mode, multimode, BiDi, CWDM, and more. It works with both 155M and 1.25G SFPs, giving you full flexibility to match your network needs. ## Frequently Bought Together - Single Mode LC Gigabit Fiber Media Converter - Includes LC SFP 20 km (12.42 Miles) LC – to UTP Cat5e Cat6 10/100/1000 RJ-45 – Auto Sensing Gigabit or Fast Ethernet Speed - Jumbo Frame - LLF Support - FLYPROFiber- 1M/3ft OS2 Single Mode LC to LC Fiber Patch Cable, SM Singlemode Duplex, SMF Fiber Optic Cable Cord, 1G/10GB, 9/125um, LSZH - BEYONDTECH LC to LC Fiber Patch Cable Single Mode Duplex - 1m (3.28ft) - 9/125um OS1 LSZH PureOptics Optic Patch Cable Series --- ## 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.lk/products/81201664-lc-single-mode-gigabit-20km-12-24-mi-built-in](https://www.desertcart.lk/products/81201664-lc-single-mode-gigabit-20km-12-24-mi-built-in) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-23*
