OTDR Overview:
Due to its low cost and ease of use, this Spectrum 1625nm FTTH network OTDR has become quite popular in recent years. We are all aware that a fiber optic network’s worth is directly correlated with its user base. Based on our thorough understanding of FTTH networks, we are providing a single 1625 wavelength FTTH PON OTDR to make things simpler for the techs and to replace the existing multi-wavelength PON OTDR (1310/1550/1625) products. Why pay a high price when you only need the 1625um to confirm the accuracy of your customer’s signal?. Designed specifically for FTTH networks, this unit can fully meet the requirements for speedy debugging of fibre optic line issues between OLT and ONT for operation.
PON OTDR description:
Features for PON OTDR:
- 1625nm wavelength test
- PON OTDR can measured on-line without interrupting the optical signal in transmission.
- More convenient to locate the fiber optic fault location.
- Quickly and accurately detect loss, breakpoint, macro bend, reflection, etc.
- Distinguish attenuation events and reflection events.
- Data saving storage.
- VFL and OPM function, suitable for various home network environment.
- Friendly to use no complicated settings.
- Only 450g, easy to carry.
- Rechargeable 3X AA (3xAA alkaline batteries
- Powered also through the USB port.
