Abstract
The invention relates to the field of optical communication network modules, and provides a 4-channel CWDM QSFP optical module, comprising a QSFP base and four optical transmitting sub-devices. The four optical transmitting sub-devices are mounted on the base in parallel, and there is a gap between each of the optical transmitting sub-devices and the base. The QSFP optical module further includes CWDM optical components for multiplexing 4-channel optical signals emitted by the four optical transmitting sub-devices. The CWDM optical components comprise a single fiber pigtail for transmitting the multiplexed optical signal, the single fiber pigtail being at least partially located in the gap. The 4-channel CWDM QSFP optical module of the invention connects the four optical transmitting sub-devices with the CWDM optical components by a reasonable method of optical fiber winding, thereby solves the problem that it is difficult to achieve single-mode fiber coupling of four LDs in a small space.
