Optical Zonu fiberoptic delay lines incorporate wideband lasers and photodiodes (fiberoptic transmitters and receivers) designed for linear analog modulation. Fiberoptics provide high bandwidth and sensitivity to facilitate long delays, and wide spur free dynamic range for operation over a variety of loss budgets. The basic advantage of a fiberoptic delay line is that long lengths

Recently, one of our network customers shared an experience, along with resulting insights, to illustrate the value proposition of our Micro-ODTR feature. Some years ago, when a machete-wielding grounds-crew was clearing brush behind the business that hired them, an optical fiber cable was cut, causing the network service of a key subscriber to go down.

The Micro-OTDR stores its measurements in the EEPROM, just like any Digital Diagnostics Monitoring (DDM) data. These are accessed by the host Equipment via the I2C port using SNMP. When linked the data is stored and not refreshed (up to 15 reflections). The user can force a new measurement via the Tx Toggle command. The

Reflections in an optical link are not a good thing for SFPs. But they make the Micro-OTDR work. Understanding reflections is important for the interpretation of Micro-OTDR test results. Micro-OTDR SFPs operate in any conventional optical fiber network, but are specified for use with Ultra-Polish (UPC) connectors, which are widely deployed and exhibit a reflectance

For years, US mobile carriers have been moving their networks to a more centralized architecture that saves on both capital and recurring costs. The CRAN (centralized radio access network) approach consists of aggregating base station base band units (BBUs) in centrally located facilities. From here, capacity and coverage are brought to venues in the area

Given the projected growth of 5G wireless networks (see adjacent chart), it is no wonder that 5G is the topic of conversation on the telecommunications scene. For CSPs the new business potential is enticing, though the technical challenges are enormous. The higher-level network issues get the most play – and rightly so – but like

The challenge for many networks has always been the limited reach the RF cabling. This is due the location of the Antenna Sin respect to Network Operating Center (NOC) doesn’t always coincide with the limitations of coaxial cable. In many instances to support the coaxial limitations extensive building modifications are required. When using a fiber

From Michael J. Hartmann VP Business Development Digital Marketing. Optical Fiber Fault Detection must be Fast, Distributed and Pervasive – To materially improve the reliability of the Access Network. The detection of a fault needs to be fast so that the operation of the network is minimally impacted. A fault should be detected, located and

In our ever-changing world Secure RF communications is a must. The Common Data Link “CDL” surpasses the limited reach the RF cabling and unsecure nature. The CDL by transporting RF signals from a few MHz to beyond 60 GHz over the tamper-proof fiberoptic cable. This means your outdoor RF and Ethernet signals can be sent
