A bosa device with power control function

Abstract

The invention discloses a BOSA device with a power control function. The BOSA device comprises an emission portion, a reception portion, and an emission terminal power control portion, the emission portion comprises a laser assembly, the reception portion comprises at least two F-P cavity filter etalons used for realizing bandwidth adjustment of transmitted spectrum and an optical detector used for converting received optical signals after filtering to electric signals in sequence, and the emission terminal power control portion comprises a data uploading and downloading interface used for butt joint with an external jumper and realization of uploading and downloading of the optical signals, a double-core optical fiber used for transmitting downloaded external optical signals and emission optical signals emitted by the laser assembly, an MEMS chip used for adjusting the power of emission terminal optical signals, and a WDM filter used for separating the external optical signals and the emission terminal optical signals. The BOSA device realizes power adjustability of an emission terminal based on the MEMS chip, in the application of TWDM-PON, industrialization is easily formed, the size is small, and the cost is low.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a BOSA (Bi-direction Optical Sub-Assembly, optical transmitting and receiving assembly) device, in particular to a BOSA device with a power control function. Background technique [0002] The demand for bandwidth for information transmission has been growing at an explosive rate. In order to meet the rapid development of network traffic, in the backbone network, 40Gbps and 100Gbps optical networks have begun commercial deployment, and 400Gbps or 1Tbps optical communication systems have also begun research. At the access network level, higher requirements are inevitably placed on network traffic and multi-service support. At present, the access network is mainly based on the PON technology of the tree-structured passive optical network, and the passive optical network TDM-PON (timedivision multiplexing-Passive optical network) based on time division multiple...

Problems solved by technology

[0003] The three technologies can effectively solve the bandwidth bottleneck problem in the future market, but each has its own problems that need to be solved urgently. For example, increasing the single-wavelength rate in the first method will inevitably lead to greater line dispersion

[0004] But even as a TWDM-PON, it also has technical problems to be solved urgently, that is, the ONU (Optical network unit) module must have a wavelength-tunable receiving function and a wavelength-tunable transmitting function, that is, the two-way wavelength of the BOSA device inside the ONU is adjustable.
