Industrial 4Ports Gigabit SFP Fiber Switch Din Rail Mounted with One SFP Transceiver 1.25G Dual Fiber SM up to 20km for Outdoor Use

Q&A
1. Q: Does this 4port Gigabit SFP fiber switch come with a power adapter?
A: The power adapter is sold separately. You could use industrial din-rail power adapter or commercial grade. The voltage can be 12-52VDC, like 12V3A power supply.
2. Q: Does it come with SFP transceivers?
A: Yes, the industrial 4port Gigabit switch includes one1.25G-LH ( SM, dualfiber, 1310nm, LC). If use other types of SFP transceivers, please use industrial grade SFP transceiver.
3. Q: Is it a managed 4 port industrial switch?
A: It is unmanaged industrial switch and no need any setting. It is plug and play, easy to use.
3. Q: What's the difference between industrial switch and commercial one?
A: The industrial switch can work in harsh environment where working tempersture is -40 to +75. The protection degree is IP40. The industrial 4port Gigabit SFP switch works more stable and reliable.
