I'd love to convert 10g fiber to 10g copper ethernet.** A: I run this switch with three (3)10G RJ45 transceivers (10Gtek for Cisco SFP-10G-T-S Compatible 10GBase-T SFP+ 10 Gigabit RJ45 Copper Transceiver 30-Meter) and one (1) DAC cable (10Gtek 10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU3M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Devices, 3m. Works like a champ. **Q: Can i use regular cat7 rj45 cables in the sfp+ to achieve 10gbe speeds, or do i need to use a different cable?** A: When using RJ45 sfp+ modules, you do not need Cat7 (not technically a US standard anyway). Cat 6a must be able to carry 10mbit for at least 100M. Cat 6 has to be able to do at least 55M, longer than any most any home or small business run is going to be. Cat 5e, while not officially rated, will generally work fine for 10gbit over the length of runs used in homes. **Q: Can I use this as 1 fiber uplink to data center then the other 3 fiber ports to different buildings and the copper to connect to another switch?** A: Yes. Just think of it as a switch. All 5 ports are on the same network. I have 2 installed essentially as you described. ## Frequently Bought Together - MikroTik CRS305-1G-4S+in Network Switch Managed Gigabit Ethernet (10/100/1000) Ethernet Power (PoE) White - 10Gtek 10Gb PCI-E NIC Network Card, Single SFP+ Port, with Intel 82599EN Controller, Ethernet LAN Adapter Support Windows Server/Linux/VMware, Compare to Intel X520-DA1(E10G42BTDA) - 10GTEK 10GBase-SR SFP+ LC Transceiver, 10G 850nm Multimode SFP Module, up to 300 Meters, for Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, Ubiquiti UniFi UF-MM-10G, Fortinet, TP-Link and More, Pack of 2 --- ## 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.pt/products/313962433-crs305-1g-4s-in-network-switch-managed-gigabit-ethernet-10](https://www.desertcart.pt/products/313962433-crs305-1g-4s-in-network-switch-managed-gigabit-ethernet-10) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-24*
