Order Information

Handling Precautions: This device is susceptible to
damage as a result of electrostatic discharge (ESD). A
static free environment is highly recommended.
Laser Safety: Even small radiation emitted by laser
devices can be dangerous to human eyes and lead to
permanent eye injuries. Be sure to avoid eye contact
with direct or indirect radiation.

Every BlueOptics© transceiver comes with a 5 year
replacement warranty and lifetime support.
For a warranty inquiry, please contact your CBO sales
representative.
This warranty only covers the first user of the
equipment.

Important Notice
Performance figures, data and any illustrative
material provided in this data sheet are typical and
must be specifically confirmed in writing by CBO
before they become applicable to any particular order
or contract. In accordance with the CBO policy of
continuous improvement specifications may change
without notice.
The publication of information in this data sheet does
not imply freedom from patent or other protective
rights of CBO or others.
Further details are available from any CBO sales
representative.

Installation
Before installation attach an ESD-preventive wrist to
ensure not to damage the transceiver or hardware.
BlueOptics© BO08C28S1 can be installed in any
Small Form Factor Pluggable (SFP) port. You can install
the BO08C28S1 regardless if the system is powered
on or off, because it is hot-swappable.
Insert the transceiver into the SFP port and remove the
dust cap.

You can now connect your cable.
