FAQs

Q: What fiber type should I use?
A: Use multimode fiber (OM2/OM3/OM4). OM3/OM4 can provide longer reach than OM2.

Q: Will this work in an SFP+ port?
A: Many SFP+ ports accept 1G SFP optics, but support is platform-dependent. Check your device documentation.

Q: Do I need the same optic on both ends?
A: Yes. Use matching 1000BASE-SX 850 nm LC modules on both ends for proper link operation.

Q: Is this hot-swappable?
A: Yes, it can be inserted or removed without powering down the host device.
