Frequently Asked Questions about 100G QSFP28

What is a 100G QSFP28 transceiver?

The 100G QSFP28 transceiver is a high-speed optical module used in data communication networks. It is designed to transmit and receive data at a rate of 100 gigabits per second (Gbps). The QSFP28 form factor indicates the modules size and that each electrical lane can transmit up to a maximum of 25Gbps.

What is the difference between QSFP28 and 100G QSFP?

QSFP28 form factor indicates the modules shape, and that each electrical lane can transmit 28 Gb/s. 100G modules use the QSFP28 form factor, although in some sources it might be simply written as QSFP.

What is the difference between SFP28 and QSFP28?

SFP28 and QSFP28 have different sizes (form factors). SFP28 generally has one electrical lane supporting up to 28 Gb/s transmission, while QSFP28 has 4x 28 Gb/s lanes.

What is the power consumption of 100G QSFP28?

Depending on the specifics of the module, our 100G QSFP28 can have a power consumption of up to 6.5W. Please refer to individual products to see the maximum power consumption of each module.

Is QSFP28 compatible with QSFP?

QSFP28 modules can’t be used in QSFP+ ports, as they don’t meet the data rate requirements.

What does the 28 mean in QSFP28?

This standardized nomenclature indicates that each electrical lane of the module can transmit or receive up to 25Gbps transmission.

Is QSFP28 backwards compatible with SFP28?

No, QSFP28 and SFP28 use different form factors and are not compatible with each other.

Can you connect SFP28 to QSFP28?

No, QSFP28 and SFP28 have different form factors and cannot be directly connected with each other.

What is the difference between QSFP and SFP module?

The difference is primarily in the form factor and data transmission rates. QSFP is larger in size and can transmit higher data rates, while SFP modules are smaller in size and transmit lower data rates.

What are the types of 100G QSFP28?

We offer 100G QSFP28 for many different applications, including SR4, LR4, LR4-20, ER4, ZR4, ZR4+, CWDM4, BIDI, PSM4, IR4, DWDM, PAM4, SWDM4, RX Only and O-Band WDM.
