QSFP28 Module

4 x 28Gbps transmission

Codeable to all major vendors

QSFP28 100GBASE transceiver modules are hot-pluggable 100G Ethernet Quad Small Form-Factor transceivers that plug into QSFP28 high-speed data ports.

Widely used across mid-range data centre applications, Newton Optics QSFP28 transceivers can transmit 100 Gbps optical Ethernet connectivity up to 40 meters over OM3 multimode fibre or up tousing OM4 multimode fibre cable.

SR4 100G transceivers transmit four 25G channels using 8 fibre cores (4 duplex pairs) to give an aggregate bandwidth of 100Gbps. 

This 100G QSFP28 transceiver can be programmed to be compatible with all major switch and server brands, such as Cisco, HP, Dell and Juniper.


All of Newton Optics transceivers are compliant with the relevant standards. Our QSFP28 100GBASE- transceivers are compliant with 100 GbE IEEE 802.3bm specifications and per channel basis to the IEEE 802.3 25GBASE-SR optical specification.



Multi-vendor Codeable Low Cost 10G, 40G, 100G.
