FAQs

Q: Do I need separate SFPs for these ports?
A: No. The ports use integrated single-mode optics with SC connectors.

Q: What fiber type is required?
A: Single-mode fiber (SMF) compatible with 1310 nm optics.

Q: Is this LR-1 card compatible with LR-2/XR optics on the remote end?
A: Yes, OC-12/STM-4 links can interoperate across LR classes if link budget and wavelengths are compatible; ensure the remote end supports 1310 nm and overall loss is within budget.

Q: What is the maximum supported distance?
A: Up to 40 km under typical optical budgets with suitable single-mode fiber.
