Oplink’s WDIH1598 is a combination of a 980 / 1550 nm filter and a 1550 nm polarization insensitive optical isolator. The Mini WDIH59 series combines a 980/1550 (1585) nm filter and a C-band 1550 nm (or L-band 1585 nm) polarization insensitive optical isolator. Both are low-cost models with excellent performance, including low insertion loss, high isolation, high return loss, and low polarization dependent loss (PDL). The WDIH1598 also offers low polarization mode dispersion (PMD). These products offer integrated solutions to EDFA applications by combining more functions into a very compact package. The product package dimension of the Mini WDIH59 is about 3.0 mm x 30 mm.
