Changing out reference cables during the insertion loss and return loss testing process to accommodate new DUT types can cause downtime for a manufacturing line and drastically reduce the efficiency of the cable production process. With single channel DUTs and reference cables, the issue may seem inconsequential. However, in the modern fibre production line every minute counts; any method that...

In optical networks where action on a message or signal is time critical, latency becomes a critical design element. Latency in communications networks is comprised of the networking and processing of messages, as well as the transmission delay through the physical fibre. Measuring and optimising this optical transmission delay can be critical in diagnosing latency issues in a data centre...

The Ultra High Resolution OSA (UHR-OSA) proposed by APEX Technologies remains a very important tool not only to measure the optical OFDM (Orthogonal Frequency Division Multiplexing) signal spectrums even with few tens of MHz spacing sub-carriers but also to adjust and adapt it to other modulation techniques. APEX-UHR-OSA incessant need in OFDM research area APEX UHR-OSAs have found a wide industrial and...

The APEX Technologies Ultra High Resolution Optical Spectrum Analyser (OSA) can be used to measure the active/passive optical component insertion loss/gain thanks to the possibility to synchronise the internal Tunable Laser Source and the OSA sweepings. In this context, the APEX OSA remains a perfect tool to measure the Fibre Bragg Grating (FBG) Sensor reflection with 1 MHz of resolution...

High return loss in a network or data centre is an issue that can cause a number of problems ranging from source stability to increased BER and a lower signal-to-noise ratio. As a result, pass/fail criteria on fibre optic connections has jumped in recent years as advancements in polishing techniques have allowed for fibre optic matings with lower reflections. Click...
