Auxora's filter block series is a broad portfolio of vertically-integrated products for optical networks using micro-optics that are designed and manufactured in house with our core processes including crystal cutting, precision polishing, thin-film coatings and high-volume automatic assembly manufacturing. These filter blocks can be used to combine 4/8 optical channels at the transmitter end as they are launched into a single-mode fiber, then function in reverse at the receiver end, with channel spacing of 800GHz for LAN-WDM, each transmitting at 25Gb/s or 10Gb/s.
