As an efficient and reliable material melting and mixing device, the fused taper coupler can improve its performance and application value, and meet the production needs of chemical and pharmaceutical industries.
The advent and development of optical fiber communication technology has brought revolutionary changes to the communication industry. At present, about 85% of the world's communication services are transmitted through optical fibers, and long-distance trunk networks and local relay networks have also widely used optical fibers.
The transceiver (optical module) is composed of optoelectronic devices, functional circuits and optical interfaces, etc.
ITU-T and IEEE standards for GPON and EPON contribute to the wide acceptance and deployment of PON respectively. Today, the deployment and upgrade of 10G PON is proceeding smoothly, including ITU-T standard XG-PON1 and XGS PON and IEEE standard 10G EPON.
FBT coupler, developed in the 1990s, has the functions of energy distribution, wavelength combination, demultiplexing of optical signals. Although after 2008, the emergence and development of PLC, the taper coupler energy sharing part of the function has been weakened, but for different energy splitting ratio, as well as the cost of low wavelength division coupler, in the current used for wavelength division module monitoring terminal (can be designed according to different schemes into different spectral ratio, bandwidth requirements), as well as for EDFA module above, Still has an irreplaceable role.
Hybrid device refers to the five most important functional devices in EDFA, namely, optical Isolator (Isolator), wavelength division multiplexer (WDM), gain flat filter (GFF), Coupler (Coupler) and TAP PD(splitter detector), which integrate two or more combined functions into one device. Under the premise of realizing the same function, the device size is greatly reduced and the cost is reduced.
optical module is composed of optoelectronic device, functional circuit and optical interface. The optoelectronic device includes two parts: transmitting and receiving. Simply put, the function of an optical module is to convert an electrical signal into an optical signal at the sending end, and then convert the optical signal into an electrical signal at the receiving end after transmission through the optical fiber.
Based on the principle of "generating photons+regulating photons", three applications of laser radar, household medical beauty and pan semiconductor manufacturing process are deployed. Juguang Technology was founded in September 2007 under the leadership of Dr. Liu Xingsheng...
