Dintek’s Light-Links OTDR

Responding to the growing need for field test instruments for the installation and maintenance of fiber-optic networks, Dintek released the Light-Links OTDR. The OTDR satisfies a range of test and measurement needs in analyzing optical networks and in doing so, empowers technicians to make fast, precise measurements. It is geared for testing of FTTx, PON, CATV, LAN, access and metro network fiber links. It is suitable for lab and factory testing, as well as live fiber troubleshooting. Featuring IP65-level protection, a 7-inch anti-reflection LCD screen, optional PON test and MMF test modules, and a multi-language display, the package includes a main unit power adapter; lithium battery; FC adapter (optional: SC/ST/LC adapter); USB connection cord; bare fiber adapter; and carrying case.

Viavi’s OneAdvisor-1000 supports high-capacity networks

At this stage in the technology’s lifecycle, 400-Gbit/sec services in the field are rare; finding portable equipment to test those circuits is a challenge. Viavi says its OneAdvisor-1000 tester is more than up to the task, providing full-rate and protocol coverage to address service activation, troubleshooting, and maintenance for 400G circuits. Compatible with fiber-optic test modules such as OTDR and WDM channel checkers, the scalable and modular OneAdvisor-1000 tests new technology including PAM-4 and KP4 FEC at 400GE. PAM-4 native support is provided via connectors and interfaces also to test 400GE. QSFP-DD and SFP-DD interfaces are also supported. The OneAdvisor-1000 is suitable for metro/core, data center interconnect, and business services testing. The platform enables advanced tests such as Optics Self-Test for QSFPx and SFPx pluggables, high-speed cable testing for data centers, RFC 2544/Y.1564, and OTN Check.

Anritsu’s MU100023A OTDR module

Anritsu introduced the MU100023A OTDR module for its Network Master Pro MT1000A optical network measuring instrument. With the module, Anritsu adds triple-wavelength support of 1310/1550-nm and 1650-nm singlemode fiber (SMF) to its existing line of OTDR modules. The new MU100023A module adds support for the 1650 nm wavelength used for live-fiber evaluations to the existing 1310/1550-nm wavelengths to enable all-in-one, triple-wavelength OTDR measurements. Like other MT1000A OTDR modules, the MU100023A can integrate visual light source and optical fiberscope options, in addition to having a built-in stabilized light source and optical power meter. Installing the MU100023A in the MT1000A offers all-in-one communications quality inspections of each optical fiber line, as well as live-fiber fault detection, Anritsu emphasizes.
