## 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
