FAQs

Q: Is this compatible with 1310 nm LR-1 optics on the far end?
A: Wavelengths must match; use 1550 nm optics on both ends for proper operation.

Q: Do I need optical amplifiers for 80 km?
A: Link budget depends on fiber loss and splices; many deployments reach 80 km unamplified, but verify total loss and margins.

Q: Are the optics fixed or pluggable?
A: The optics are integrated on the line card and use SC connectors.

Q: What fiber type is required?
A: Single-mode fiber (SMF) optimized for 1550 nm operation.
