The R5101-P from OEQuest is a Polarisation-Maintaining (PM) Fiber Optic Circulator that operates at a wavelength of 2000 nm. It delivers a peak power of 500 mW and has a wavelength range of ±20 nm. This fiber optic circulator has a minimum polarization extinction ratio of 18 dB and peak isolation of 30 dB. It has a minimum cross-talk of 50 dB, insertion loss of 1.4 dB, and return loss of 50 dB. This has two working axes & four configuration ports and supports polarization maintaining PM fiber. It is available in a compact package that measures 5.5 mm x 5.5 mm x 35 mm and is ideal for use in EDFA & Raman amplifiers, fiber sensors, testing instruments, and medical equipment applications.
