Optical Circulators (L-band)
Finisar’s latest generation of optical circulators have been optimized for use in next -generation DWDM L-band (1565-
1605nm) network systems. These L-band circulators deliver extremely low insertion loss and high isolation across the
entire L-band, and offer minimal insertion loss ripple, polarization dependent loss (PDL) and polarization mode
dispersion.
Features :
Low insertion loss across the L-band
Low PDL and PMD
High isolation
Epoxy -free optical pat h for high pow er han dlin g
