A: Use 50/125 µm multimode fiber (MMF) with LC connectors for optimal reach up to 550 m.

Q: Does this module support digital diagnostics?
A: Yes, it supports DDM/DOM for real-time monitoring of optical power and temperature.

Q: Is it compatible with 1G SFP ports on EX and QFX switches?
A: Yes, it is intended for Juniper platforms with 1G SFP slots, including many EX and QFX models.

Q: Are patch cords included?
A: No, fiber patch cords are sold separately.

Q: Can it be mixed with LX modules on the far end?
A: No. SX requires an SX module on the far end over MMF; LX is for SMF.
