iwdm isolator/wdm hybrid component (1550nm/980nm) for edfa-j9九游会真人游戏第一品牌

iwdm
isolator/wdm hybrid component (1550nm/980nm)

iwdm integrates the functionalities of a polarization insensitive optical isolator and a 1550/980nm wdm.this product offers integrated solutions to edfa application by combining more fuctions into a very compact package,it can help to save fiber coiling space,reduce splicing and fiber coiling works while raising up the system reliability and increasing module design efficiency.

iwdm features
miniaturized size
high isolation
ultra low pdl&pmd
highly stable&reliablility
epoxy-free optical path
rohs&reach compliant

iwdm application
