100G QSFP28

100G optical QSFP28 transceivers are a cornerstone of today’s network infrastructure, offering a compact size, low power consumption, and high performance. These transceivers are essential for 100 Gigabit Ethernet, EDR InfiniBand, and 32G Fibre Channel, sharing the same footprint and faceplate density as 40G QSFP+ modules.

The 100G QSFP28 is engineered with four high-speed channels, supporting data rates from 25Gbps to 40Gbps with an enhanced electrical interface for signals up to 4x28Gbps. They are predominantly used in 100G Ethernet, Data Center Interconnect (DCI), Infiniband QDR and DDR Interconnect, and Enterprise networking.

Common Types of 100G QSFP28 Modules:

• QSFP28 100G SR4: Ideal for data centers needing short transmission distances of 5m to 100m.
• QSFP28 100G PSM4 and CWDM4: Perfect for networks with transmission needs of 500m to 2km. While CWDM4 is costlier, it requires only two single-mode fibers, making it an efficient choice for enterprise networking and 100G Ethernet.
• QSFP28 100G LR4: Supports up to 20km transmission using LC single-mode fiber cables. It converts 4x25Gbps electrical signals into a single 100G optical channel using LAN WDM technology.
• QSFP28 100G ER4 and ZR4: Utilizes WDM technology for maximum transmission distances of 40km and 80km, ideal for optical communication and DCI applications.
• QSFP28 100G BiDi: Enables bidirectional data over a single fiber, leveraging existing duplex LC MMF infrastructure. It’s a cost-effective solution for network capacity upgrades, used in 100GE Ethernet, data centers, and High-Performance Computing (HPC).
• QSFP28 100G Single Lambda: 100G Single Lambda optical module (e.g. 100G LR1, 100G ER1) is an innovative high-speed transmission module using single-wavelength technology, achieving speeds of up to 100Gbps on a single wavelength. This simplifies optical design, reducing component count and complexity, lowering costs and power consumption
