The 100G QSFP28 SWDM4 provides 100Gbps bandwidth over a standard duplex multi-mode fiber eliminating the application for expensive parallel multi-mode fiber infrastructure and offers a seamless migration path from duplex 40G to 100G. It is supported on all mainstream switches QSFP 100G ports and can be used for links up to 70m of OM3 fiber or up to 100m of OM4 fiber or 150m of OM5 fiber. The SWDM4 Tx port transmits 100G data over 4 x 25Gbps wavelengths, and the Rx port receives data over 4 x 25Gbps wavelengths. The wavelengths are in the “short wavelength” range (850nm, 880nm, 910nm, 940nm).

The 100G QSFP28 SWDM4 are well known cause of the optical interface is duplex LC connector, when in deployment, it is convenient and smooth upgrade from duplex LC cable structure, it is the special application in finance industry and the government organization, reuse the existing 40G MPO-8 fiber infrastructure.

FAQ;

Q: I had the QSFP-40G-SWDM4 used in my network, can I upgrade the network with QSFP-100G-SWDM4?

A: Yes, the existing duplex LC Multimode fiber infrastructure for 40G QSFP+ SWDM4, are perfect matching the connection application of 100G QSFP28 SWDM4, you can reuse the fiber cables and upgrade the switch and transceiver only.
