Optical fibre monitoring software detects occasional faults
A new software package allows the Yokogawa AQ7275 optical time-domain reflectometer (OTDR) to be used in unattended mode for detecting and monitoring faults occurring occasionally or at regular or irregular intervals in fibre-optic networks.
Advanced utility option allows ScopeCorder to pre-analyse waveform data during acquisition
A new advanced utility option in Yokogawa's Xviewer waveform display and analysis software boosts the hard disk recording capability of the recently introduced DL850 ScopeCorder by allowing an engineer to pre-analyse waveform data while the acquisition is still in progress. The new DL850 advanced utility option for Xviewer uses a file transfer tool to transfer recorded data files from the DL850 to a PC without stopping actual hard disk recording.
Dynaload Expands Communication Options with Ethernet
Transistor Devices' Dynaload Division has announced the addition of Ethernet communication capabilities to its popular RBL, MCL and WCL series of programmable electronic loads.
RJ45 jack with magnetic filter and LED light pipes
The Y-ConJack-31 is a new RJ45 connector jack for PCB with integrated magnetic filter, and LED light pipes for the function display. The jack is particularly suited to industrial applications such as industrial ethernet. The function principle of the integrated magnetic filter module definitely makes a decisive contribution to the signal conditioning, thanks to the galvanic separation (potential separation) and the additional components. Overlaye...

Single Port PoE Controller Simplifies Power Sourcing Equipment Design
Linear Technology has introduced the LTC4263, an autonomous single-channel Power Sourcing Equipment (PSE) controller with an onboard MOSFET for use in IEEE 802.3af Power Over Ethernet (PoE) compliant systems. Requiring only a few external components, the IC is a complete single-port PSE solution that detects, classifies and provides isolated 48V power to Powered Devices (PDs) connected to it. Offering standard-compliant AC or DC methods to sense ...
High Power PD Controllers with Built-In Switchers Address IEEE 802.3at PoE+ Standard
Linear Technology has introduced the LTC4269-1, LTC4269-2 and LTC4278, IEEE 802.3at compliant Power over Ethernet (PoE+) interface controllers with integrated switching regulators for high-power Powered Device (PD) applications up to 25.5W and beyond. The new IEEE 802.3at definition, also known as the PoE+ standard, simultaneously expands the power budget and improves the classification mechanism used by Power Sourcing Equipment (PSE) and PDs to ...
Isolated 12-Port Power over Ethernet PSE Controller Chipset Eliminates Optos for Lowest Solution Cost
Linear Technology introduced the LTC4270/ LTC4271 isolated 12-port Power Source Equipment (PSE) controller chipset designed for use in IEEE 802.3at (PoE+) Type 1 and Type 2 compliant Power over Ethernet (PoE) systems.
Quad & Single LTPoE++ PSE Controllers Deliver Up to 90W
Linear Technology Corporation introduces the LTC4266A and LTC4274A, 4-port and single-port Power over Ethernet (PoE) controllers for Power Sourcing Equipment (PSE), delivering up to 90W of power to Powered Devices (PDs). The current IEEE standard, 802.3at (also known as PoE+), limits the maximum available power to PDs to 25.5W. By the time the standard was ratified in 2009, applications were already demanding higher power levels. The LTC4266A and...
Linear Technology Commemorates 30 Years of Analog Innovation
Founded 30 years ago, Linear Technology Corporation commemorated three decades of innovation in analog integrated circuits. Founded in September 1981, at the dawn of the digital revolution, some questioned the wisdom of founding a company focused purely on analog technology. Over these 30 years, the worldwide analog market has grown from $2 billion to over $40 billion today, and Linear has prospered with that growth.
