If you have a APC fiber you need to connect it to, adapters are available to do that. **Q: Does it support 220v ?** A: Yes. The adapter states input voltage 100-240VAC You will need an adapter if you get the US plug model as mine came with a standard US adapter. **Q: Is it compatible with a hp j9660a or a dell powerconnect 2724?** A: I am using this with the MC220L Transceiver converter and it works great. However you can use this in any switch that has a SFP or SFP+ port. Both the HP and Dell you stated do have SFP ports so you are good on either. **Q: Is this module compatible with Netgear Switch?** A: They are pretty much interchangeable. I put them in tp-link switches but from what I got at my local fiber optic store is that they are all the same. ## Frequently Bought Together - TP-Link Gigabit SFP module | 1000Base-LX Single-mode Fiber Mini GBIC Module | Plug and Play | LC/UPC interface | Up to 10km distance (TL-SM311LS) - 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 --- ## 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.kg/products/120057608-tp-link-gigabit-sfp-module-1000base-lx-single-mode-fiber](https://www.desertcart.kg/products/120057608-tp-link-gigabit-sfp-module-1000base-lx-single-mode-fiber) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-09*
