FAQ
1、Question：What are CWDM, DWDM, SFP and GBIC used for? What kind of company buys them?
Answer：First, CWDM (Coarse wavelength division multiplexing) and DWDM (Dense wavelength division multiplexing) are 2 kinds of technology, compared with single wavelength technology. They are used in optical network because it saves cost.
SFP and GBIC are transceiver modules. They are used to connect switches and cables. There are slots on the switches. SFP can be inserted and removed according to different demand.
2、Question：What is the best method to make fiber runs with SFP connectors 100M+?
Answer：Making fiber runs with SFP and distance over 100m is easy to reach. Both single-mode SFP and multi-mode SFP transceivers can meet the requirement. It's all depends on your actual need.
3、Question：Do you offer 40G QSFP+ transceivers that operate at an industrial temperature range?
Answer：Sorry, 40G QSFP+ transceiver that operate at an industrial temperature range are currently not available, but in development. Please stay tuned.
