The QSFP28 transceiver is designed for 100G speeds using the 4x25 wiring specification. QSFP28 transceivers make deploying 100GbE networks as easy as 10GbE networks, having a strong ability to increase density, decrease power consumption, and decrease price per bit.

QSFP28 is the exact same footprint as the 40G QSFP+ module, “Q” for “Quad”. Just as the 40G QSFP+ is implemented using four 10-Gbps lanes, the 100G QSFP28 is implemented with four 25-Gbps lanes. In all QSFP versions, both the electrical lanes and the optical lanes operate at the same speed, eliminating the costly gearbox found in CFP, CFP2, and the CPAK. The QSFP28 module has an upgraded electrical interface to support signaling up to 28Gbps signals, yet keeps all of the physical dimensions of its predecessor. As QSFP28 technology becomes even maturer, QSFP28 transceivers become more and more popular in 100G optics market.

Since its surge, the QSFP28 transceiver has gained increasing popularity among enterprises or organizations, as it increases density and decreases power and price per bit. 100G QSFP28 makes it as easy to deploy 100G networks as 10G networks.

QSFP28 increases front-panel density by 250% over QSFP+. Although QSFP28 has the same form factor and the maximum number of ports as QSFP+ module, the lane speeds are increased from 10Gbps to 25Gbps.

With the fiber optic technology becoming maturer and more available, the choice of high-bandwidth switches, routers, and adapters which feature QSFP28 will be diversified, ensuring data centers to scale to 100G networks with the simplicity as 10G networks. Wiitek supplies a large number of QSFP28 transceivers available in 100G QSFP28 PSM4, SR4, CLR4, LR4 and ER4 types.
