Review: Compatible with older Netgear switches - My home LAN consists of 3 different switches (2 Netgear 24 port managed and a DIN Rail 8 port PoE switch, designed to withstand the high temperatures in my attic) as well as about 50 devices. Originally I had all the switches wired with CAT5, but I had cheated and run one of the CAT5 cables alongside a 120 volt line, in order to get it into a room that was difficult to wire otherwise. I knew it was against "code" but figured as long as the 120 volt line didn't interfere with the Ethernet signal, then it would have to work. It worked fine for a couple of years but eventually I decided to redo that and ran fiber through my attic and over to all the switches. I used these Transceivers to terminate the fiber. Now I'm code compliant and ready for faster speeds when I need it.
Review: Worked well with my udm Pro - Worked well with my UDM PRO

## Questions & Answers

**Q: What transceiver model should i purchase for my fortiswitch-124e-fpoe to reach over 400m in single mode?**
A: This Gigabit SFP LC Single-Mode 1000BASE-LX Transceiver is fine, and you can get it through https://www.amazon.com/gp/product/B00U8PN0NQ/ref=ask_ql_qh_dp_hza.

**Q: Same model for Sender And receiver ?**
A: Yes.  There is a transmitter and receiver built in.  Think of it like the transmit and receive over copper. Works the same way. Just requires a single fiber in each direction instead of a wire pair.

**Q: Will this work with Stratix switch?**
A: Yes.  The Stratix is essentially a Cisco Catalyst.

**Q: Do you have sfp work with hirschmann rsp20 switch?**
A: Hello, thanks for the consultation. 

We have no experience with Hirschmann rsp20 switch and there's no instruction about its compatibility, but the datasheet shows that it supports 100Mbps SFP. You may purchase this 10/100/1000Base-T Copper SFP to have a test through
https://www.amazon.com/gp/product/B01L6PQ6I2/ref=ask_ql_qh_dp_hza?th=1

If it doesn't work, we will provide you with a return refund.

### ⭐⭐⭐⭐⭐ Worked well with my udm Pro
*by J***E on March 27, 2026*

Worked well with my UDM PRO

### ⭐⭐⭐⭐⭐ Works great with Ubiquiti (and other brands as well)
*by C***P on September 2, 2024*

Works perfect with Ubiquiti network switches. I bought tons of these for a campground WiFi deployment with fiber backbone utilizing their 8-port aggregation switches. These were plug and play compatible and reports gigabit links between all of the nodes. All of this is replacing legacy CAT6/copper network which was prone to weather/lightning interference. Ive used 10Gtek products in the past for smaller setups and I’ve never had an issue. If you aren’t certain about what to get, their support is excellent and they will point you in the direction of which SFPs to buy if you provide them the details of your equipment. Great product, great price, and great support
