Finisar Optical Circulators (L-band) Finisar's latest generation of optical circulators have been optimized for use in next -generation DWDM L-band (15651605nm) 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 path for high power handling Specifications : Grade A Grade B Parameters Unit Center Wavelength Operating Wavelength Range Insertion Loss* Isolation (Over operating wavelength range at 23C) Isolation (Over operating temperature range at 1585nm) Polarization Dependent Loss Polarization Mode Dispersion Optical Return Loss Cross Talk Optical Power Fiber Length Package Size (DXL) Operating Temperature Range Storage Temperature Range nm nm dB dB 40 35 dB 40 35 dB ps dB dB mw m mm o C o C Min Typ Max Min 1585 1565-1605 0.5 0.7 Typ 0.15 0.05 50 50 Max 1585 1565-1605 0.7 0.9 0.15 0.05 50 50 500 1 500 1 5.5 X 44 -5 to +70 -40 to +85 Connector Options None, FC/PC, FC/APC Fiber Type All Ports: Corning SMF-28 * Over all wavelengths and temperatures Ordering Information: Part Numbers for Standard Grades without connectors: Grade A: 1012182 Grade B: 1012183 Dimensions: (Unit:mm) Port1 (Green) Port2 (Clear) Port3 (Red) 44 Finisar Shanghai Inc. 3-5Floors, Suite 72, 887 Zu-Chong-Zhi Rd., Zhangjiang Hi-Tech Park, Pudong, Shanghai, China 201203 Main: +86-21-51317030 Fax: +86-21-51317022 Email: salessupport_shanghai@finisar.com Website: www.finisar.com 5.5 Finisar Corporation 1308 Moffett Park Drive, Sunnyvale, CA 94089-1133, USA Main: (408) 548-1000 Fax: (408)543-0083 Email: sales@finisar.com Website: www.finisar.com May 05 Rev.
