1655/ 56- Series
XMD MSA-compatible 10 Gb/s Cooled EML TOSA
Product Brief
Description
The 1655 (40km) and 1656 (80km) - Series XMD MSA com-
patible 10 Gb/s transmitter optical subassembly (TOSA)
integrates a high-speed electroabsorptive (EML) laser,
a monitor photodiode and a micro-TEC in a small form-
factor metallized ceramic package. It is designed for use
in SFP+ 10Gb/s transceivers and other types of optical
modules for high-speed telecommunication and data ap-
plications.
The 1655/ 56 -Series is available in the full range of C-band
ITU-T wavelengths operating at 10 Gb/s per channel. The
device exhibits excellent wavelength stability, supporting
operation at 100 GHz channel spacing over 20 years (as-
suming an end-of-life aging condition of <±90 pm), with
low hazard rates (~100FIT wearout over 20 yrs.).
1655/ 56 -Series uses Avagos’ newest iteration of EML chip,
which operates at a higher temperature than its predeces-
sor, and therefore reduces TEC power dissipation when
in cooling mode. Overall power dissipation in SFP+ and
other transceivers can therefore be reduced signicantly.
