LinkScope Sourcing 11
LinkScope Sourcing 11 coordinates fiber OTDR inquiries for business buyers in the United States. The work is to capture a configuration, contact factories, and place their replies side by side. The desk is an independent sourcing partner. It is not a meter manufacturer, a calibration laboratory, or an authorized channel for any instrument brand.
What the desk will and will not put in writing
Captured from your brief
- Wavelength set, fiber mode, and connector on the optical port.
- Dynamic range and both dead zones, each tied to a pulse width.
- Quantity in pieces or kits, US destination, and requested timing.
- Optional budget with currency and a per-instrument or whole-order basis.
- A high-end, mid-range, budget, or undecided supplier preference, stored as a preference.
Left for the named supplier
- Whether a model is in production, and the lead time that supplier states.
- FCC or safety evidence, if the exact handheld requires it for your import path.
- Calibration traceability for the serial number that will ship.
- Software licenses for trace analysis and any file-format limits.
- Compatibility between a launch reel and the port on that model.
Public standards, including ITU-T optical-fibre recommendations, are used as question prompts. A recommendation number on this site does not mean a proposed meter complies with it. Measurement accuracy stays a datasheet claim until the supplier attaches the test conditions.
The desk does not publish customer counts, founding years, or savings figures. Those numbers would describe a factory or a past project this site has not audited. If a supplier offers an alternative wavelength module, the reply should mark it as an alternative so it is not averaged into the original line.
Compatibility questions the desk repeats to every factory
Two meters can share a color screen and still differ at the optical port. The questions below are asked so a compatible-looking photo does not close the comparison early.
Name the wavelengths installed, the fiber mode, the connector, the pulse widths behind the dead-zone numbers, and the trace file format. State exclusions for launch fiber, adapters, freight, and calibration.
Single-mode and multimode remain a plant decision. Quoting an 850 nm meter into a 1550 nm feeder is a mismatch, not a commercial alternative. Refurbished and new units can both be requested, but battery condition and the calibration date have to be visible before the prices are read as peers.
A dynamic-range number becomes usable when the supplier names the pulse width and averaging time behind it. Ask whether 1310 nm, 1550 nm, and 1625 nm are in one module or sold as an extra wavelength. A 20 µs pulse can extend the displayed range and still miss a splice that a 100 ns pulse would resolve, while a 3 ns or 10 ns pulse is the question when the event dead zone must stay near the connector. Request the attenuation dead zone at that same pulse, including whether it is under 10 m or longer than 20 m. A 150 m launch reel and a 500 m launch reel are different kit lines. Connector mating-cycle wear sits on the launch cord and adapters. Ingress protection and battery runtime stay datasheet questions if the meter lives in a vehicle. This desk does not turn those open lines into a savings figure or a certification claim.
Return loss and insertion loss of the patch cord under test are properties of that cord and its end faces. The OTDR can display events. It does not clean a connector or certify a short jumper that sits inside the dead zone.

Paste wavelengths, quantity, destination, and open questions into the requirement field. There is no file upload on this form. A written list is enough to start factory outreach.
