TNCS-O: Shelf Controller with Integrated OTDR/OSC
• NCS2K shelf controller: compatible with M15 and M6
• Supports up to 2 Optical Service Channel Termination
with embedded OTDR Capabilities
• Supports USB Management through the ECU
The OTDR behaves like a ”radar” in the optical domain.
• A probe optical pulse is launched from one fiber’s end
• the resulting back-scattered light is measured against time (or distance from source).
The measurement provides:
• Fiber length
• Fiber type (att. Slope)
• Position and loss / reflections of optical connectors
• Position and loss of splices
• “Visual feedback” of any concentrated event.
OTDR Basics
TNCS-O W/Integrated OTDR/OSC
• NCS 2015 supports 2x Node Controller Line Cards (TNCS-O)
• Each TNCS-O Line Card supports 2x OTDR/OSC ports
• 1 OTDR per Degree with up to 4 Degrees per NCS 2015 chassis – Dedicated OTDR
• Digital – Bit Stream instead of High Power Optical Pulse
• In Band – Take measurements directly @ 1518nm, no extrapolations
• Bi-directional operation – Tests both fibers and both directions of the fiber with a single device
NODE A
OTDR & OSC Operations
• Using TX of Near-End XFP and TX on Far-End
allows to scope the Top Fiber Left-to-Right and the
Bottom Fiber Right-to-Left
• OSC flows Left-to-Right in the Top Fiber and Right-
to-Left in the Bottom fiber
• OSC can run in parallel with OTDR scans on the
span fibers – will be available with Hybrid Mode

OTDR Integration Details • Operates In Band @ 1518nm
• Bi-directional operation – Tests both fibers and both directions of the fiber with a single device
• Able to support:
• OTDR-only Operation – During system turn up for faster fiber scanning
• OSC-only Operation – For maximum throughput (e.g. SW Download)
• Hybrid OSC & OTDR Operation (HW Ready) – Continuous monitoring of fiber with OSC connectivity
• OTDR Sensitivity SW Configurable:
• Zone #1 (Up to 1Km) – Fiber Connectivity check through CO Patch Panels
• Zone #2 (Up to 25Km) – Check Insertion Losses and Back Reflection
• Zone #3 (Up to 80Km) – Measurement Accuracy to detect issues w/10m resolution
• Zone #4 (Above 80Km) – Maximum Length spanning w/20m resolution
• Expert Mode – User can manually set Scan parameters

When the OTDR measures a variation of Insertion Loss/Reflection
higher than threshold, an entry is raised in the alarm panel.
