Is comhpháirt snáithín-chúpláilte é na haonraitheoirí optúla snáithíní ardchumhachta 980nm 1030nm 1030nm 1064nm a ligeann do gach comhartha solais polaraithe (ní hamháin an solas polaraithe i dtreo sonrach) iomadú feadh snáithín i dtreo amháin ach ní sa treo eile. Go feidhmiúil, tá sé cosúil go leor le dé-óid snáthoptaice-leictreach. Tá gá le haonraitheoirí optúla snáithíní ardchumhachta 980nm 1030nm 1064nm i gcórais snáthoptaice i go leor ról, agus is é an ceann is coitianta ná cosc a chur ar sholas frith-fhrithchaite ag teacht ar ais anuas snáithín ó athiontráil agus cur isteach ar oibríochtaí léasair. Soláthraíonn Boxoptronics 1W, 2W, 3W,..., 10W nó Polarization ardchumhachta eile a chothaíonn aonraitheoirí snáithíní.
A Phase Shifted FBG Fiber Bragg Grating introduces phase discontinuities into a fiber grating, creating a narrow transmission window in the FBG's reflection spectrum. The transmission wavelength varies with the amount of phase shift. Phase-shifted FBGs can be used as demultiplexers in dense wavelength division multiplexing (DWDM) systems. The magnitude, location, and point of the phase shift have a significant impact on the performance of the demultiplexer.
The wavelength of a pump laser diode varies at different operating temperatures. The 980nm pump FBG Fiber Bragg grating wavelength lock is used to stabilize the wavelength and intensity of the optically amplified pump laser. By precisely locking the pump laser diode through feedback of a small portion of the laser signal, this type of control significantly improves the power and wavelength output accuracy and reliability of the pump laser. Specifically, it eliminates spectral mode jumps in the pump laser, reduces power intensity fluctuations caused by temperature and pump drive current variations, and greatly improves the performance of the pump laser. It is also commonly used for stabilizing distributed feedback lasers in wavelength division multiplexing systems, the optical path of tunable lasers, and fiber resonators in Raman systems. Depending on the customer's locking requirements for the pump laser, single-grating or dual-grating configurations are available. The dual-grating configuration further improves the output spectral characteristics of uncooled pump lasers.
Ligeann an Attenuator Snáithín Athraitheach Lámhleabhar Optúil don úsáideoir maolú an chomhartha sa snáithín a athrú de láimh de réir mar a tharchuirtear tríd an bhfeiste é. Is féidir na VOAanna seo a úsáid chun láidreachtaí na comhartha i gciorcaid shnáithíneacha a chothromú go beacht nó chun comhartha optúil a chothromú agus raon dinimiciúil an chórais tomhais á mheas. Tairgtear na VOAnna gan teorainn nó cuirtear deireadh leo le nascóirí FC/PC nó FC/APC. Le haghaidh stíleanna cónascaire eile nó iarratais saincheaptha, téigh i dteagmháil le Tacaíocht Theicniúil.
