4 x 10 Optical Transceiver Module Cisco Catalyst 3850 C3850-NM-4-10G
◦ Up to 40G of wireless capacity per switch (48-port RJ45 models)
◦ Support for up to 100 access points and 2000 wireless clients on each switching entity (switch or stack)
● 24 and 48 10/100/1000Mbps data PoE+ and Cisco UPOE models with energy-efficient Ethernet (EEE)
● 24 and 48 100Mbps/1/2.5/5/10 Gbps Cisco UPOE models with energy-efficient Ethernet (EEE)
● 12- and 24-port 1 Gigabit Ethernet SFP-based models
● 12- and 24-port 1/10 Gigabit Ethernet SFP+-based models
● 48-port 1/10 Gigabit Ethernet SFP+ model with 4 fixed 40 Gigabit Ethernet QSFP+ uplinks
● Cisco StackWise-480 technology provides scalability and resiliency with 480 Gbps of stack throughput
● Cisco StackPower™ technology provides power stacking among stack members for power redundancy
● Five optional uplink modules, with 4 x Gigabit Ethernet, 2 x 10 Gigabit Ethernet, 4 x 10 Gigabit Ethernet, 8 x 10 Gigabit Ethernet4, or 2 x 40 Gigabit Ethernet QSFP+ ports
Figure 1. shows the following network modules:
● 4 x Gigabit Ethernet with Small Form-Factor Pluggable (SFP) receptacles
● 2 x 10 Gigabit Ethernet with SFP+ or 4 x Gigabit Ethernet with SFP receptacles
● 4 x 10 Gigabit Ethernet with SFP+ receptacles (supported only on the 48-port Gigabit Ethernet models or on the 12-port or higher 10 Gigabit Ethernet models)
An SFP+ receptacle supports both 10 Gigabit Ethernet and Gigabit Ethernet modules, allowing customers to use their investment in Gigabit Ethernet SFP modules and upgrade to 10 Gigabit Ethernet when business demands change without having to do a comprehensive upgrade of the access switch. In contrast, SFP receptacles can be used only as Gigabit Ethernet ports, as shown in the examples in Table 2.
