980/1550nm WDM/Isolator
Hybrid Combination
WDIH1598 Series
Product Description
Oplink’s WDIH is a combination of a 980/1550nm filter and a 1550nm polarization
insensitive optical isolator. The WDIH is a low cost model with excellent perfor-
mance including low insertion loss, high isolation, high return loss, low polarization
dependent loss (PDL), and low polarization mode dispersion (PMD). This product
offers integrated solutions to EDFA applications by combining more functions into
a very compact package.
Oplink can provide customized designs to meet specialized feature applications.
Also, Oplink offers modular assemblies that integrate other components to form
a full function module or subsystem.
