1. Evaluation of transmission path characteristics

Waveform and error rate measurements with reduced characteristic loss can be performed by using HCB in combination with DSO/BERT on high-speed signal transmission paths where signals are reflected by providing measurement probe points. Therefore, accurate evaluation of transmission path characteristics is possible. It can also be used as an interface converter for a DUT with an SFP cage mounted.

Target of Evaluation (DUT) – DSP, FPGA, PHY

2. Optical Transceiver Characterization

Using the HCB board for compliance testing of optical transceivers, it is possible to perform measurements in an optimized evaluation environment. Transceiver characteristics can be easily evaluated without high-speed circuit design and development experience.

Module Compliance Board

You can characterize MSA compliant optical modules. We have a lineup of CFP, CFP2, CFP4, CFP8, SFP, SFP+, SFP28, QSFP+, QSFP28, and QSFP-DD, and we also provide a GUI that conforms to each MSA and has excellent operability.

Host Compliance Board

Electrical characteristics can be measured by inserting it into the port of the equipment that the customer is developing. By using it in combination with BERT and DSO, you can evaluate signal integrity (waveform quality) from ASIC, FPGA, etc. to ports.

Loopback Module

BER can be checked for each port by generating a PRBS signal or arbitrary signal on the customer's board and looping it back at the module port. We have a lineup of CFP, CFP2, CFP4, CFP8, SFP, SFP+, SFP28, QSFP+, QSFP28, and QSFP-DD types, and can operate with functions that comply with each MSA.
