EMI Spring Single Port QSFP28 Cage Aluminum Heat Sink For 100G Ethernet
1. QSFP28 Knowledge Extension
QSFP transceivers are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over multi-mode or single-mode fiber. QSFP modules are commonly available in several different categories:
4 x 1 Gbit/s QSFP
The original QSFP document specified four channels carrying Gigabit Ethernet, 4GFC (FiberChannel), or DDR InfiniBand.
4 x 10 Gbit/s QSFP+
QSFP+ is an evolution of QSFP to support four 10 Gbit/sec channels carrying 10 Gigabit Ethernet, 10GFC FiberChannel, or QDR InfiniBand. The 4 channels can also be combined into a single 40 Gigabit Ethernet link. It is usually for the application of Data center, 40G Ethernet, Infiniband, and other communications standards.
4 x 14 Gbit/s QSFP+ (QSFP14)
The QSFP14 standard is designed to carry FDR InfiniBand, SAS-3. or 16G Fibre Channel
4 x 28 Gbit/s QSFP+ (QSFP28)
The QSFP28 standard is designed to carry 100 Gigabit Ethernet, EDR InfiniBand. or 32G Fibre Channel. This transceiver type is also used with direct-attach breakout cables to adapt a single 100GbE port to four independent 25 gigabit ethernet ports (QSFP28-to-4x-SFP28). Sometimes this transceiver type is also referred to as "QSFP100" or "100G QSFP" for sake of simplicity.
A series of QSFP28 Cage assemblies without integrated connectors supplied by GLGNET, Widely used in the networking, telecommunication and data centre industries. The next generation of high-speed I/O devices, supporting 40G to 100G Ethernet Application. The Press Fit copper alloy cages offer EMI spring or EMI gasket variants and are fully backward compatible with existing QSFP optical modules ( Transceiver ) and cable assemblies.
