FAQs

Q: Will it work over existing duplex MMF cabling?
A: Yes, it is designed for duplex LC OM4 multimode fiber for distances up to 30 meters.

Q: How is SL4 different from SR4?
A: SL4 operates over duplex LC using shortwave wavelength multiplexing, while SR4 uses MPO-12 with 4 parallel MMF pairs.

Q: Can I run this over OM3?
A: It may work over OM3 at reduced reach; OM4 is recommended to achieve the specified 30m.

Q: Does it support DOM/DDM?
A: Yes, real-time digital diagnostics are supported.

Q: Is it suitable for breakout to 4x25G?
A: No, SL4 is intended for 100G duplex operation, not 4x25G breakout.
