SFP (Small Form Factor Pluggable) is a compact, hot-swappable transceiver module that converts electrical signals into optical signals (and vice versa), enabling long-distance communication between devices. One of the main advantages of SFP modules is their hot-swappable nature, which allows them to be inserted or removed without powering down network devices.
SFP (Small Form-factor Pluggable) is a compact, hot-swappable module used in network devices such as switches, routers, and servers to provide network connectivity and is widely used in network communications. By using different interfaces and single-mode or multimode fiber depending on the distance, it enables network flexibility, facilitating deployment and maintenance, making it an indispensable component for network construction.
The QSFP28 100G CWDM4 optical module uses the QSFP28 form factor. It is a 100G transmission mode based on single-mode Coarse Wavelength Division Multiplexing (CWDM) technology. It is hot-swappable and employs a duplex LC interface. It transmits optical signals at four central wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm. Each wavelength transmits 25G. Using CWDM technology, the QSFP28 100G CWDM4 optical module multiplexes these four central wavelengths onto a single-mode fiber for transmission. When used with single-mode fiber, the transmission distance can reach 25G. km, meeting the various long-distance transmission requirements of data center networks.
A 1G SFP module, also known as a 1 Gigabit Small Form-factor Pluggable (SFP), is a transceiver used in telecommunications and data communications applications. It is designed to support communication over optical fiber or sometimes copper network cables at speeds of up to 1 Gigabit per second (Gbps).
The QSFP28 (Quad Small Form-factor Pluggable 28) transceiver is a compact module that can be hot-swapped and is designed to support high-speed data transfer in today’s network. With up to 100 Gbps speeds, it is frequently used within data centers, enterprise networks, and telecommunications infrastructure. The QSFP28 transceiver supports Ethernet, Fiber Channel, InfiniBand, and many other communication standards, but at the same time, it allows both optical and electrical connections. Therefore, this highly efficient transceiver is indispensable when there is a need to meet the growing bandwidth requirements in high-performance networking environments.
