FAQs

Q: What does ULH indicate?
A: ULH denotes Ultra Long Haul—engineered for supervisory links across very long optical spans.

Q: Is this for payload traffic?
A: No, it carries supervisory/control traffic only via the Optical Supervisory Channel.

Q: What fiber and connector are required?
A: Single-mode fiber with an LC connector.

Q: How is reach determined?
A: Reach depends on the optical design, amplification, and platform-specific link budget of the ULH system.
