What are the characteristics and advantages of QSFP28-100G-LR4?

The rapid development of 100G Ethernet brings huge market demand to the 100G light module. Among the many 100G light modules, the QSFP28 light module has become the most popular light module with its smaller size and low power consumption. The following will be introduced from the perspective of definition, working principles, application scenarios and common questions.

definition:

QSFP28-100G-LR4 is a full dual-worker light module that can be inserted, which meets the IEEE 802.3bA standard. The dual LC interface is 1295, 1300, 1304, and 1309nm. The modular fiber jumping line can reach a transmission distance of 10 kilometers.

working principle:

Convert the 4 -way 25Gbps electrical signal to 4 LAN WDM light signal, and then use MUX or WDM to reuse it as a single channel to achieve 100G light signal transmission. At the receiving end, the module uses Demux to remove 100G light input as 4 LAN WDM light signal, and then convert it to 4 electric signal and then output channels.

Application scenario:

QSFP28-100G-LR4 light module is very suitable for long-distance connections in data centers and corporate networks. The 100G light module supplied can be widely used in brand switches such as Huawei, Ruijie, Cisco, H3C, and ZTE of the data center machine room.

Frequently Asked Questions:

Q1: Can QSFP28-100G-LR4 be connected with 100G CFP LR4 light modules?

A1: Their transmission rates are 100G, and they work on the same working wavelength (1310Nm), so they can connect to each other.

Q2: QSFP28-100G-LR4 light module provides customized services?

A2: QSFP28-100G-LR4 light modules all provide customized services, just provide compatible brands and models.
