The development of 100G Ethernet has brought a large market demand for 100G optical modules, among which 100G QSFP28 has become the most popular 100G optical module with it small size and low power consumption. 100G QSFP28 optical modules include SR4, eSE4, PSM4, LR4, CWDM4, ER4, ZR4, etc. In this article, ETU-LINK will focus on 100G QSFP28 LR4 optical modules. LINK) will focus on introducing 100G QSFP28 LR4 optical module.

The 100G QSFP28 LR4 optical module uses LAN WDM technology to convert four 25G electrical signals into four optical signals at the transmitter side and then multiplex them in a single channel for transmission. At the receiver side, the multiplexed 100G optical input signals are then demultiplexed into four LAN WDM optical signals and then converted into four electrical output signals.

The 100G LR4 optical module works at 1295, 1300, 1304, 1309nm, with duplex LC interface, which is very suitable for long distance connection in data center and enterprise network, such as 100G direct connection and interconnection. 100G direct connection solution is very simple, only need to insert two QSFP28 LR4 optical modules into the corresponding 100G switch port, and then connect the two modules with an LC fiber patch cable. The 100G direct connect solution is very simple, just insert two QSFP28 LR4 optical modules into the corresponding 100G switch ports and connect the two modules with an LC fiber patch cable.

The ETU-LINK QSFP28 LR4 optical module 100G interconnect solution is also easy to connect, as shown in the figure below, by using a rackmount fiber cassette, MTP fiber adapter panel and MTP backbone patch cable to interconnect the high density QSFP28 LR4 optical modules. Among them, the adapter panel and fiber cassette are used to simplify cable management.

The above is the 100G QSFP28 LR4 optical module introduced by ETU-LINK, if you don't know anything, please leave your comments.
