Extreme Networks 10338 Compatible 10GBASE-T SFP+ Copper Transceiver Module (30m, RJ45)


The Extreme Networks 10338 compatible 10G copper SFP transceiver module is equipped with an RJ45 connector, reaching a link up to 30m at 10GBASE-T data rate over cat6a/cat7 Ethernet copper cabling. Besides, the 10 Gigabit copper module is backward compatible with 1GBASE-T, and intermediate rate 2.5GBASE-T, 5GBASE-T, providing multi-gigabit Ethernet deployment. QSFPTEK manufactured 10GBASE-T SFP+ module is compliant with IEEE 802.3an, IEEE 802.3az, and SFP+ MSA. The 10G RJ45 module uses the electrical signal to transmit data, allowing an upgrade to 10G by reusing existing copper architectures. This 10G SFP+ RJ45 copper transceiver caters to 10 Gigabit Ethernet (10GbE) copper connections, delivering a cost-effective NBASE-T copper solution. It has been tested on host devices to ensure full compatibility with 10G-T ports on Extreme equipment, such as 10GBASE-T switches, enterprise routers, and server network interface cards (NICs).

    Order processing is fast, (packing and shipping). As each country has different customs regulations, the shipper handling your shipment needs to inform customers in advance what information they need from us to clear customs quickly if an item gets stuck in customs! Until we find it out and we need to start import licenses, documents and figure out what the correct HS code for the product is, finding the correct HS code can be challenging for someone who is not in logistics/shipping.

  • Jayden lIM United States of America

    I purchased the incorrect cable on the initial order and after discussions with Wendy and the tech they were able to recommend two products that should work. I purchased the above transceiver along with a 15m (49ft) LC UPC to LC UPC duplex OM4 multimode PVC (OFNR) 2.0mm fiber patch cable and now have 10gbe from my NetGear RBK752 router to my QNAP 2104-S switch . Big thanks to Wendy and the team for all the help with this.

    Transceivers typeSFP-10G-SR




  • Jayden lIM United States of America

    I have nothing to say other than that this is exactly what I want and it works perfectly. I'll notice that I put it in a 10G port and it shows up when the other end is hardcoded to 1000Mbps (1Gbps). The other side is running fine at 1Gbps and the traffic is going through fine, so no problem at all. QSFPTEK is definitely on my list of preferred suppliers!

    Worked for exactly what I needed it for and no better price to be found! I can confirm these work with the Cisco Meraki MS225.

  • Tre Brown United States of America

    The price is fantastic and these work perfectly on my HPE switches. They also report their operating temperature, BTW. Combine with LC-LC fiber (30m) and you get a very cheap 10 Gb/s backbone in your house!

  • Stretch J. United States of America

    I am using these SFP transceivers to connect two JUNIPER switch over fiber. They worked perfectly, no speed issues noticed. They have been working for several months 24-7 without issue. Very satisfied with the results.

  • Dale Dryden United States of America

    We just finished building our new office building right next to our old one. I needed to connect the old server room to the new one, an x1052 to a N2048 stacked with a N2048p. Dell wanted about $$$ for each transceiver! No way! These worked perfectly.

  • David Kumar Venezuela

    The test effect of the sample order is very perfect, the after-sales service experience is very well, and the cost performance ratio is high. Now I directly place the order according to the project requirements.

  • L. United States of America

    I have tested a few weeks. The SFP transceiver works perfect on my Nexus 5596T switch. The price is also attractive. I highly recommend

    Transceivers type SFP-10G-T-S




  • Canada

    These modules appear indistinguishable from the OEM versions, and work perfectly. I'm running a pair between Netgear XS series managed 10Gbe switches, and everything worked out of the box with no tweaks or settings required.
