Which 40G MMF duplex transceiver should I choose, QSFP-40G-SRBD or QSFP-40G-SWDM4?

TARLUZ currently offers two 40G transceivers that operate over duplex multimode fiber, QSFP-40G-SWDM4, and QSFP-40G-SRBD transceivers. Both transceivers operate at multimode fiber and are widely deployed in the industry. QSFP-40G-SWDM4 and QSFP-40G-SRBD are using different technology, so they are not able to use each other. QSFP-40G-SWDM4 Transceiver TARLUZ 40G QSFP+ SWDM4 transceiver provides 40Gbps bandwidth […]

Introduction to VSFF Connector

VSFF Connector is the next-generation connector for fiber optics, especially the high-density data center cabling network. It is short for a very small form factor connector, compared with traditional SFF connector (Small Form Factor connector) like Duplex LC and MTRJ, etc, it is much more compact. It utilizes a reduced ferrule pitch to enable a […]
