Auxora Inc.: WDM Bidirectional Optical Sub-Assembly Core (BOSA Core)

Feb. 6, 2022
Auxora’s Bidirectional Optical Sub-Assembly (BOSA) Core enables customers to re-use the existing PON BOSA structure for 5G mid-haul bidirectional WDM transmission application.
Designed and developed for 5G mid-haul bidirectional WDM transmission applications, Auxora’s Bidirectional Optical Sub-Assembly (BOSA) Core enables customers to re-use the existing PON BOSA structure. The traditional PON BOSA structure has two WDM filters at 45 deg and 0 deg positions to mux/demux the 1.25-Gbps or 2.5-Gbps transmitter and receiver signals at 1310 nm and 1490 nm, respectively. Due to the large wavelength separation of 180 nm (1490-1310nm), the angle of incident of the filters are relatively less sensitive.

Judge’s Comment: “This BOSA module enables the higher speed BiDi modules to reuse the 90 degree conventional geometry, which was previously thought to be impossible. The wireless bidi application is fast growing, making this potentially very important.”
