MSBR Series 25 Mediant 500L MSBR
Hardware Installation Manual 5. Cabling the Device
5.1.2 Fiber-Optic Gigabit Ethernet
The device supports up to two pairs of 1.25 Gbps optical, small form-factor pluggable (SFP)
transceiver modules (see note below).
Caution Laser
This device contains a Class 1 LED/Laser emitting device, as defined by 21CFR 1040
and IEC825. Do not stare directly into the beam or into fiber optic terminations as this
can damage your eyesight.
Care in Handling Fiber Optic Cabling
1. Excessive bending of the Fiber Optic Cable can cause distortion and signal losses.
2. Ensure the minimum bending radius recommended by the Fiber Optic Cable supplier.
3. Incoming optic cabling from the network infrastructure can originate from the top of
the rack or from another shelf within the rack. Preserve the minimum-bending ratio
indicated by the cable manufacturer.
4. To ensure full high-availability capabilities, the configuration of the interface to the IP
backbone must include certain redundant features from which two separate fiber optic
cables are entering the device.
Notes:
• The SFP module and fiber-optic cable are not supplied. It is recommended that you
purchase the SFP modules from AudioCodes. For a list of orderable SFP modules,
see Appendix A on page 43, or contact your AudioCodes sales representative.
• This AudioCodes device has been evaluated with the laser transceiver modules
(SFP) listed in Appendix A on page 43. If other SFP modules are used, the person
installing the device is solely responsible for the usage of correct SFP modules to
comply with local, applicable laser safety requirements and certification. AudioCodes
will not be held responsible for any damage to human body or equipment caused as a
result from the usage of SFP modules that are not listed in Appendix A on page 43.
To connect the fiber-optic WAN GbE port:
1. Remove the protective dust plug from the SFP transceiver module. Save the dust
plugs for future use.
