The OBL-301A is a high-performance, easy-to-use diagnostic tool designed for fiber maintenance, locating faults and general troubleshooting. The OBL-301A utilizes much of the same technology used in an OTDR, such as a graphical representation of the fault location, but at a much lower price point than an OTDR. Up to 1,000 test results can be stored onboard and later transferred to a PC, via a built-in USB port. The onscreen interface has been engineered for ease of use and utilizes convenient "Hot Keys" for quick, simple testing. Water, shock and dustproof, the OBL-301A is reliable and built to last. The unit will operate for up to 8 hours on the included NiMH rechargable battery and includes an AC/DC adapter. Sold, serviced and supported in the USA, the OBL-301A is a workhorse, well-suited for inside plant, outside plant and FTTx applications.
