. WDM filter, 50dB transmission isolation, pass 1640~1660nm, reflect 1290~1635nm.
The Filter WDM with high transmission isolation can pass one wavelength and reflect the other wavelength. The WDM splitter is always used for CATV network. You can also use it to design your own special optical path for your system.
Features

Reflection wavelength: 1290~1635nm
Transmission insertion loss: ≤1.0dB
Reflectiong insertion loss: ≤0.6dB
Fiber type: SMF-28e ultra fiber with 900um loose tube
Applications
CATV network
Optical Transmitters & Transceivers

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.
