Polarizing beam splitter, 1550nm, splitting polarizations, 250um bare fiber, 0.8m length.
It is built on PM collimator and Wollaston prism, with the all-glass technique sealed process. It can combine two polarization state into one single-mode fiber or split single mode into two vertical polarization states. Mostly used in Raman amplifier, combine two vertical polar states to get a double power light.
You can see it's different from the fiber coupler which is used for splitting optical power. But you can use it to help you understand the polarization beam splitter.

Q&A:
Q: What's your Payment terms?
A: We accept TT & Western Union for payment.
Q: How to order a sample?
A: You can contact us directly and tell us your requirements on any of our products.
Q: Could you print our company logo or design on the products?
A: Yes, we can accept your need but we will share the charge with you.
Q: If we decide to move forward with our order what is the next step?
A: You place an order first. Then we will send you PI. After you settle the payment by TT or the Western Union. We will arrange production for you.
Q: What is your normal production lead time for a first order and then for repeat orders?
A: It depends on the product you need. For example, if you purchased a 1550nm fiber circulator for your first order, and then you look for it again, but we will check the material of it and tell you the delivery time.
Q: Do you have warranty policy?
A: Yes, we have. We provide 12 months maintenance warranty.
