With the increase of data transmission and the increasing demand of users, the application of 100G optical network is more and more extensive, which is the product of the era of big data. Nowadays, the main types of 100G optical modules launched in the market are: CXP optical module, CFP optical module, CFP2 optical module, CFP4 optical module and QSFP28 optical module. QSFP28 optical module is widely used in the market. The 100G QSFP28 optical module is mainly divided into SR4 / IR4 / CIR4 / LR4 / ER4 and other models. ETU-Link will inreoduce the 100G QSFP28 optical module in detail.

100G QSFP28 optical module features:

The size of the 100G QSFP28 optical module is 4 parallel data channels, and the transmission rate of each channel increases from 10Gbit / s to 25Gbit / s, so as to achieve the transmission rate of 100Gbps. Compared with the CFP series optical module, the 100G QSFP28 optical module has smaller volume and higher density wiring.

The power consumption of QSFP28 optical module is generally less than 3.5W. Using QSFP28 optical module can directly upgrade from 25G to 100G without 40G, with low cost. However, the power consumption of other 100G optical modules is usually between 6W and 24W, so the power consumption of QSFP28 optical module is lower than that of other 100G optical modules.

100G QSFP28 optical module type:

Application of 100G QSFP28 optical module:

High speed optical module applied to 100G Ethernet. It adopts the packaging form of QSFP, with small volume. The QSFP28 optical module has four signal channels, each of which has a maximum transmission rate of 28Gbps and multiple transmission distances. It is applied to 100G connection of core switch and core router in data center.

100G QSFP28 optical module interconnection solution:

In the development of 100G Ethernet technology, 100G QSFP28 optical module is widely used, among which the optical module labeled QSFP28 LR4 is the most common. "G" of 100G refers to the unit of optical signal transmission rate. LR refers to the transmission distance, which generally represents 10KM transmission.

At present, the technology of 100G Ethernet has become mature, and the deployment of 100G network of enterprises, institutions or governments has gradually stepped into the right track. The 100G optical module supports 4 × 25G data transmission mode, and because of its high port density, low power consumption and low cost, it is favored by data center users, usually used with 100G switch. ETU-Link module is fully compatible with Huawei, Cisco, Huasan and other brands of switches, can provide a full range of optical module solutions to help users build a low-cost and efficient network system.
