OPLINK’s 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 passband, low insertion loss, and high isolation, which makes it ideal
for combining pump (980nm) and signal light (1550nm) in Optical Fiber Amplifier Sys-
tems. All OPLINK products are epoxy-free in the optical path. It is used in high-power
applications in DWDM systems. OPLINK MWDM devices are Bellcore GR -1209 quali-
fication tested.
