FAQ
1、Question: Is it possi le to order 400 to 500 of these??
Answer: Of course! Please contact us at "sales2@HTF.com", we will offer you a reduced price for this bulk order. Look forward to cooperate with you.
2、Question: Just making sure, I can plug an LC fiber connector into these correct?
Answer: Yep, these are LC. Make sure you are using SMF.
3、Question：Will this work with 1g (not 10g) sfp ports in Cisco switches?
Answer：Yes. As long as the rate of both ends are consistent.
4、Question：Should I use CAT6a or SFP+ to connect my office to my server room?
Answer：
SFP+ is just a small form factor transceiver module for network gear so you can get SFP+ transceiver for copper (cat6a) or fiber optic. The cost of labor can sometimes make it worth the upgrade to fiber optic cable and the transceivers are fairly inexpensive. Fiber isn't affected by environmental issues like copper, so you can string it near
Electromagnetic gear like fluorescent light ballasts, transformers, etc. Fiber optic also does not pass electricity so the damage that a lightning strike can cause is isolated to just that side.
5、Question：I wish to connect two switches in my network rack. I can use the 1000BASE-T RJ45 connectors or SFP. Why should I consider using SFP?
Answer：The backplane on the switches may be designed so that the SFP ports have dedicated bandwidth specifically designed to cross-connect switches. “uplink port”, so to speak. If that’s the case, you will get better throughput and lower latency between switches using the SFP ports because they’re configured differently on the backplane but not necessarily because of the ports themselves.
