FAQs

Q: How does LRL4 differ from LR4?
A: LRL4 provides similar duplex CWDM operation at 1310 nm but targets shorter reach up to about 1 km, offering a lower-cost alternative to 10 km LR4.

Q: What cabling does it use?
A: Standard LC duplex single-mode fiber.

Q: Can I break this out to 4x10G?
A: No. LRL4 duplex modules are intended for 40G point-to-point links, not 4x10G breakout.

Q: Is DOM supported?
A: Yes, digital diagnostics monitoring is supported.
