SFP and SFP+ Modules

The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These
transceiver modules are field-replaceable, and they provide the uplink interfaces when installed in an
SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors
for copper connections.
Use only Cisco SFP and SFP+ modules on the switch. For the latest information about supported SFP
and SFP+ modules, refer to the Cisco Transceiver Modules Compatibility Information at:
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_support_tables_list.html
For information about SFP modules, see the SFP module documentation and the
SFP+ Modules" section on page

The Catalyst 3850 switch supports the SFP module patch cable (CAB-SFP-50CM), a 0.5-meter, copper,
passive cable with SFP module connectors at each end. This cable is only used with 1-Gigabit Ethernet
SFP ports to connect two Catalyst 3850 switches in a cascaded configuration.

Description
This module has four 1-Gigabit SFP module slots. Any combination of
standard SFP modules are supported. SFP+ modules are not supported.
If you insert an SFP+ module in the 1-Gigabit network module, the SFP+
module does not operate, and the switch logs an error message.
See Figure 3-1 on page
This module has four slots that support the following combinations:
• Two slots (left side) support only 1-Gigabit SFP modules and two slots
(right side) support either 1-Gigabit SFP or 10-Gigabit SFP modules.
• Three slots (left side) support 1-Gigabit SFP modules and one slot (right
side) supports 10-Gigabit Ethernet SFP+.
Supported combinations of SFP and SFP+ modules:
• Slots 1, 2, 3, and 4 populated with 1-Gigabit SFP modules.
• Slots 1 and 2 populated with 1-Gigabit SFP modules and Slot 4 populated
with one 10-Gigabit SFP+ module.
Slot 3 and Slot 4 each populated with 10-Gigabit SFP+ modules.
•
See Figure 3-2 on page
This module has four 10-Gigabit slots or four 1-Gigabit slots.
This is only supported on the 48-port models.
Note
