FAQ For Juniper 40GBASE-SR4 QSFP
1. Are Juniper 40G QSFP+ modules compatible with all Juniper switches?
Yes, they work with most Juniper devices including QFX, EX Series, MX routers, and PTX platforms.
2. Do these modules support hot-swapping?
Yes, all Juniper QSFP+ modules support hot-swappable installation.
3. What type of fiber do I need for SR4 modules?
SR4 uses multimode fiber (MMF) with MPO/MTP connectors.
4. Can I break out 40G QSFP+ to 4×10G?
Yes, some QSFP+ modules support breakout cables for 4×10G connections, depending on the switch model.
5. Are DAC and AOC interchangeable?
No. DAC is copper-based and ideal for short distances. AOC is fiber-based for longer distances up to 100m.
6. What is the maximum distance for LR4 modules?
Up to 10 km over single-mode fiber.
