100G QSFP28 PSM4 Optical Transceiver: A Cost-Effective Choice for Modern Data Centers
100G QSFP28 PSM4 Optical Transceiver | 100G Ethernet Optical Module Supplier
Explore the advantages of the 100G QSFP28 PSM4 optical transceiver in data center networking. It utilizes a 1310nm DFB laser, features 4 x 25Gbps channels, MPO connectivity, and complies with the IEEE 802.3bm standard.
What is a 100G QSFP28 PSM4 Optical Transceiver?
With the continued growth of cloud computing, artificial intelligence workloads, and hyperscale data centers, network infrastructure must support higher bandwidth while remaining cost-effective. The 100G QSFP28 PSM4 optical transceiver has become one of the most popular solutions for high-speed data center connectivity.
PSM4 (Parallel Single-Mode Quad-Channel) technology enables the transmission of 100Gbps Ethernet traffic using four independent optical channels, each with a channel rate of 25Gbps. This architecture provides a reliable and cost-effective solution for short- to medium-distance single-mode fiber links.
QSFP28 PSM4 modules are widely used in:
Data Centers
Cloud Computing Platforms
Enterprise Networks
AI Computing Clusters
High-Performance Computing (HPC)
Telecommunications Infrastructure
How does a 100G PSM4 module work?
The 100G QSFP28 PSM4 transceiver converts four 25Gbps electrical signals into four parallel optical signals for transmission over single-mode fiber.
Transmission Architecture
The module includes:
4 Transmit Channels (Tx)
4 Receive Channels (Rx)
1310nm DFB Laser Array
MPO/MTP Optical Interface
Each channel transmits data independently at a rate of 25Gbps, with a total bandwidth of up to 100Gbps. Unlike CWDM4 technology, PSM4 eliminates the need for wavelength division multiplexing, reducing optical circuit complexity and deployment costs.
