Notes:
1. SONET OC-48 LR-2/SDH STM L-16.2, Gigabit Ethernet and 1X/2X Fibre Channel compliant.
Compatible with SONET OC-12 and OC-3. Supports FEC at 2.67Gb/s.
2. Tested with a PRBS 2
31
-1 test pattern interspersed with 72 consecutive ones and 72 consecutive zeros
unless otherwise specified.
3. Attenuation of 0.275 dB/km is used for the link length calculations (per GR-253 CORE). A 2dB
penalty is included for dispersion on >2Gb/s data rates. Distances are indicative only.
Please refer to
the Optical Specifications in Table IV to calculate a more accurate link budget based on specific
conditions in your application.

VII. Regulatory Compliance
Finisar transceivers are Class 1 Laser Products and comply with US FDA regulations.
These products are certified by TÜV and CSA to meet the Class 1 eye safety
requirements of EN (IEC) 60825 and the electrical safety requirements of
EN (IEC) 60950. Copies of certificates are available at Finisar Corporation upon request.
VIII. Digital Diagnostic Functions
Finisar FTLF1621P1xCL SFP transceivers support the 2-wire serial communication
protocol as defined in the SFP MSA
1
. It is very closely related to the E
2
PROM defined in
the GBIC standard, with the same electrical specifications.
