The Coarse WDM Module is expanding the bandwidth of Metro/Access Networks. The 4 channel and 8 channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20 nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.
The 1064 nm In-Line Polarizer is designed to pass light with one specific polarization while blocking the other polarization. It can be used to convert unpolarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high speed communication systems and test instruments where high polarization extinction ratio is required.
The Unidirectional Integrated Tap Photodiode (UTPD) integrates the functionality of an optical coupler and a photodiode for optical network's power detection. The unidirectional feature allows the PD to respond to power from input port only. It can be applied for channel power monitoring in DWDM system, in-line optical network switching protection monitoring (OLP), reconfigurable optical add/drop multiplexers (ROADM), and gain/attenuation monitoring in EDFAs, network's power detection, etc.
AFR's SteadiBeam® is the best Isolator designed for high power pulsed fiber lasers. Two versions of design are compatible with lasers of 100 W and 200 W respectively. Under multiple patented technologies, the SteadiBeam® isolator delivers unparalleled performance of aberration-free and thermal lensing-free beam quality at any output power level. It also provides high isolation for reflection coming from all spatial angles.
The Dense Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard and ITU standard.The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.
