As optical interconnect speeds continue to increase, the 100G optical transceiver is currently experiencing a surge in demand within the data center market. The QSFP28 100G PSM4 optical transceiver is a high-speed, medium-range optical module used in data center environments to enable fast and reliable data transmission. Its use of single-mode fibers and parallel optics technology make it a popular choice for high-bandwidth, intra-data center connections.
The QSFP28 100G PSM4 optical transceiver operates through four independent channel, transmitting data at 25Gbps per channel for a total of 100Gbps. On the transmitter side, an electrical signal is converted to optical signals using 1310nm laser sources, with MTP/MPO connectors directing signals into the fibers. The receiver uses photo-detectors to convert optical signals back to electrical form. PSM4's parallel optics technology enables medium distance connection, typically up to 10km, ideal for data centers. It adheres to industry standards, ensuring compatibility and serving as a key component in high-speed data center communications.

A 100G to 100G direct connection involves linking two QSFP28 100G PSM4 transceivers directly with single-mode optical fibers and MTP/MPO connectors, enabling high-speed data transfer at a combined rate of 100Gbps between two networking devices.
25G to 100G migration involves upgrading from 25G to 100G data transfer speeds by replacing the existing 25G transceivers and cabling with QSFP28 100G PSM4 transceivers and associated single-mode optical fibers, enabling a four-fold increase in data throughput.
QSFP stands for "Quad Small Form-factor Pluggable Plus 28."
Yes, the use of QSFP28 100G PSM4 transceivers in legacy systems depends on the compatibility of the existing hardware and infrastructure with QSFP technology. Compatibility should be verified with the specific legacy system's documentation and requirements.
No, the QSFP28 100G PSM4 is not suitable for long-distance data transmission. It is designed for medium connections, typically up to 10km, within data centers or high-performance computing environments. For long-distance transmission, other optical transceivers with different specifications, such as those using DWDM or coherent optics, would be more appropriate.
The QSFP28 100G PSM4 is a high-speed optical transceiver with a data rate of 100 gigabits per second (Gbps). In terms of speed, it provides a very high bandwidth suitable for demanding applications.
