Note3: For update of the equipments and strict control of raw materials, EOPTOLINK has the ability to supply the
customized products since Jan 1, 2007, which meet the requirements of RoHS6 (Restrictions on use of certain
Hazardous Substances) of European Union.
In light of item 5 in RoHS exemption list of RoHS Directive 2002/95/EC, Item 5: Lead in glass of cathode ray
tubes, electronic components and fluorescent tubes.
In light of item 13 in RoHS exemption list of RoHS Directive 2005/747/EC, Item13: Lead and cadmium in optical
and filter glass. The three exemptions are being concerned for Eoptolink’s transceivers, because Eoptolink’s
transceivers use glass, which may contain Pb, for components such as lenses, windows, isolators, and other
electronic components.
Description
The EOL2-1696-22-X Series is highly integrated, serial optical transponder module for
high-speed, 10Gbit/s data transmission applications. The module is fully compliant to IEEE
802.3ae standard for Ethernet, making it ideally suited for 10GbE datacom (rack to-rack, client
interconnection) applications. The transponder module comprises a transmitter with a directly
modulated CWDM EML laser, a receiver with a APD photodiode, a XAUI-Attachment Interface,
an
integrated
Coder
/Decoder
and
multiplexer
/
de-multiplexer
(SERDES:
Serializer/Deserializer).
The transponder operates within a wide case temperature range of -5°C to +70°C and offers
optimum heat dissipation and excellent electromagnetic shielding which enables high port
densities for 10GbE systems. A 70 pins electrical connector and a duplex SC connector optical
interface assure that connectivity is compliant to the X2 and XENPAK MSA.
This module is designed for single mode fiber and operates at a nominal wavelength of CWDM
wavelength. There are eight center wavelengths available from 1470nm to 1610nm, with each
step 20nm.
Digital diagnostic monitoring (DDM) is implemented and fully compliant with X2 DDM architecture.
The unit monitors temperature, receive optical power, transmit optical power, and laser bias
current.

Thermal Management
The transponder is designed for an operation within a case temperature range between -5 to
+70°C at an altitude of < 3km. The built in heatsink provides an optimized thermal performance.
The user needs to guarantee per system design not to exceed this temperature range. It has to
be considered that in case of usage of multiple modules on a single hostboard that there is a
temperature rise among the modules hosted side by side (see figure below). Airflow direction and
air speed needs to be chosen accordingly. For further information it is referred to the MSA
document.
