General Description Phytrex PBR-310C BERT System (hereafter called PBR-310C) is an perfect manufacturing testing gear aim for 10Gb/s level optical and electrical devices or modules. It provides wide bandwidth and continues data rates between 8.5Gb/s ~ 11.1Gb/s and extended data rate down to 125Mb/s to 5Gb/s. It can also provide symmetric and asymmetric test especially on optical components and transceiver module compliance to today s most popular application such as 10G-PON,10GE-PON and SFP+. Figure 1: Basic BERT Function Block Diagram PBR-310C provides the variable patterns and receiver was built-in clock recovery unit, "synchronized loss" detector and error lamp could provides an useful indication for manufacturing purpose. The remote control interface generally provides the USB or RS232 serial port, with the development API for Labview, VB and Microsoft C#.NET versatile developing platform.

It allows a one-shot eye diagram test for a valid signal from 8.5~11.1Gb/s without any trigger input. Extrapolated eye contour lines display the eye opening for even lower BER levels, more. The display allows the quick check for relative eye parameters. Eye masks can be loaded from a library and eye mask violation check can be set from 0~30% margin for the DUT waveform testing criteria. The result screen can be printed and saved for documentation purpose. Figure 3: User control interface including Setting, BER, History and Eye Diagram Test four folders 3
simultaneously. Figure 6: Eye Diagram Measurement UI Eye contour and Histogram Eye opening is a key characteristic for a device. More deeper views with BER and eye contour simultaneously are much desiable. eyetrex provides eye contour and histogram on vertical /horizontal axis..
