40G SR BiDi, 40G/100G SR BiDi,100G SR1.2 and 400G SR4.2

How to upgrade sig ansmission from 10G to 40G and 100G in a data center with existing multi-mode dual fiber cabling?

How to implement the transmission of 40G and 100G optical signal in a multi-mode dual fiber optic network?

AscentOptics' 40G SR BD and 100G SR BD series products employ multi-mode single fiber bi-directional optical transceiver design, providing excellent solutions to these issues.

How does 400G QSFP-DD achieve a one-to-four application in multi-mode fiber, similar to 40G QSFP+ optcal modules? By also adopting a multi-mode single fiber bi-directional optical module design, the 400G QSFP-DD4.2 and 100G QSFP28 SR1.2 series optical modules can achieve this application.

Many customers have various questions about the 40G SR BD, 40/100G SR BD, 100G SR1.2 and 400G SR4.2 series of products. We aim to provide a clearer understanding of these products through a simple introduction.
