New Products |
By Nick Flaherty

Yamaichi Electronics has benchmarked signal integrity connectors up to 112G-NRZ and is planning versions that support 224Gbit/s PAM4 modulation for optical networking in data centre applications.

The market requirements of 112Gbps-PAM4 connectivity for optical transceiver pluggable modules are constantly increasing and Yamaichi plays an important role in the 112G and 224G standardisation with 112Gbit/s PAM4 connectros for the OSFP, QSFP, QSFP-DD, SFP, DSFP, NGSFP-DD and CFP form factors. Also available are a modular mezzanine connector and high-speed jumper cable interconnect product.

The SFP and DSFP formats support up to 112Gbps-PAM4 per differential pair while NGSFP-DD is the next generation small form factor pluggable with double density.

The QSFP and QSFP-DD host connectors support up to 112G-PAM4 per differential pair.
