OC-3/STM-1 And OC-12/STM-4 Analysis And Emulation Card(w/ GigE And USB 2.0)
LightSpeed1000™
Voice, data, and video traffic is exploding as smartphones, IP TV, video streaming, and "cloud" based services takeoff. A majority of the backbone transport for these applications continues to be SONET and SDH optical transmission networks. A dominant protocol for IP transport is PoS (Packet over SONET) and another is ATM (Asynchronous Transfer Mode). Both schemes are packet based, with ATM using fixed size packets of 53 bytes called "cells", and PoS using variable packet sizes closely matching to Ethernet frames. GL's LightSpeed1000™ hardware platform (PCIe Card and USB Pod) is capable of OC-3/12 and STM-1/4 wire-speed processing on quad optical ports for functions such as wire-speed recording and wire-speed playback of Unchannelized and Channelized ATM, PoS, and RAW Traffic.

Firmware for High-speed HDLC Mode
OP-FW10
OP-FW10 is firmware to upgrade protocol analyzer LE-7200/LE-3200 to dedicated analyzer that is specialized for High-speed HDLC communication up to 10Mbps. By installing this OP-FW10 to LE-7200/LE-3200, HDLC measurement processing such as the trigger and filter that were processed by software of the analyzer can be replaced to the hardware processing by FPGA built in the analyzer. Therefore, a maximum speed of HDLC supported is vastly improved. After installation of OP-FW10, You can switch to the usual firmware that supports multi protocol by pressing “SHIFT” and “0” keys at the same time when turning on the power of the analyzer. Therefore, it saves you trouble to reinstall firmware.

Understanding TEM, TE, and TM Waveguide Modes
Energy can propagate through a medium or through what is currently believed to be a vacuum. Propagation modes vary depending upon the type of energy and the nature of the medium.Electromagnetic energy is transmitted in waves. Like sound, it may propagate equally in all directions, the wave energy radiating in concentric shells corresponding to amplitude. Or it may be directional, focused to form a tight beam.View more Understanding TEM, TE, and TM Waveguide Modes

Oil Immersed Transfer Standard
esi SR1030 Series
The esi SR1030 transfer standards consist of 12 equal steps. These steps are available in increments of 1 (SR1030-1), 10 (SR1030-10), 100 (SR1030-100), 1k (SR1030-1k), 10k (SR1030-10k) and 100k (SR1030-100k). The esi SR1030 provides four-terminal connections for each step or for series and parallel combinations of these resistance steps using the optional Series-Parallel (SPC102), Parallel Compensation Networks (PC101) and shorting bars (SB103). This improves power dissipation, stability and errors due to variance in temperature. The esi SR1010 and esi SR1030 are used for the same applications and are alike in configuration. The esi SR1030 differs from the esi SR1010 in that it is specially sealed, and values below 100 k are filled with oil to improve changes due to thermal variations.
