The collimator is the base device of optics fiber passive component. the collimator is designed for long working distance and large spot of opticdal beam, The collimator has the advantage of low insertion loss, High return loss, High power handing long working distance and large spot of optical beam......

 single channel Coarse WDM is based on a patented athermal platform for optical devices. This multiplexer features ultra low insertion loss, superb thermal stability, and unparalleled reliability. The technology is a lead-free packaging platform and contains no epoxies in the optical path. Green CWDM is Telcordia GR-1221 and GR-1209 tested, qualified for uncontrolled environment applications, and is in compliance with industry green initiatives such as Rohs and WEEE.

High-Isolation Micro-Optic Wavelength Division Multiplexer (HWDM) is based on thin-film filter technology and metal bonding micro-optic packaging. This component is used to combine or separate 1310 and 1550nm band signal. The HWDM device offers a very flat and wide passband, low insertion loss, and much higher isolation than the MWDM device. This product is ideal for high-power Optical Amplification Systems and WDM Network applications. All products are epoxy-free in the optical path.  HWDM devices are Bellcore GR-1221 qualification tested.

      Micro-Optic Wavelength Division Multiplexer (MWDM) is based on thin-film filter technology and metal bonding micro optics packaging. This device offers very flat and wide passbands, low insertion loss, and high isolation which makes it ideal for combining pump(980nm) and signal light(1550nm) in Optical Fiber Amplifier Systems. In DWDM systems, this component is used in high-power applications. All  products are epoxy-free in the optical path.MWDM devices are Bellcore GR-1221 qualification tested.
