What is 100G SFP Module

With the rapid development of the optical communication industry and the increase of demands, the low-speed optical modules in the previous time have been unable to meet the requirements of transmission. Under such circumstances, the 100G optical modules are more and more attentive in the market due to their high speed.

CFP Multi-source agreement (MSA) defines the requirements for hot-swappable transceivers to be applied to 40G and 100G network transmissions, including next-generation high-speed Ethernet (40GbE and 100GbE). The CFP optical transceiver supports the transmission of multiple rates, protocols and link lengths on Single-mode and multimode fibers, including all physical media-related (PMD) interfaces included in the IEEE 802.3BA Standard.

Most of these switch vendors choose the smallest form factor transceiver: the QSFP28 transceiver. It’s the smallest module available, and has the lowest power consumption among those that are capable of handling 100G traffic. It’s also notable that the QSFP28 has the same physical size as the QSFP+ commonly used for 40G traffic. This means that switch vendors can increase the traffic throughput by a factor 2.5 without the need to redesign the front panel of their switches.

With the improvement of 100G technology, the actual use of 100G products by global high-end users has gradually increased. A large number of data center users are already using 100G master node connections, and operators’ networks are also using 100G connections. 100G will open up a new network communication. The “wide” era will continue to bring us surprises in the next few years.
