Qnap QSW-308-1C 10GbE Switch with 5-Speed 10GBASE-T/ NBASE-T and 
Gigabit Ethernet
 
Overview
The QSW-308-1C is a 3-port 10G SFP+ and 8-port Gigabit Unmanaged Switch, 
providing three 10GbE SFP+ ports (with one 10GbE SFP+/RJ45 combo port) and eight 
Gigabit ports. The QSW-308-1C allows you to instantly upgrade to a hybrid 
high-speed network environment at a cost-effective price and is compatible with 
10GbE and NBASE-T technologies to support up to five speeds (10G / 5G / 2.5G / 
1G / 100M). The SFP+/RJ45 (copper) combo port also provides higher transmission 
speeds when used with existing cables. With its desktop size and silent 
operation, the QSW-308-1C perfectly blends into homes and offices while 
providing high performance, low latency and superb functionality.

The QSW-308-1C provides three 10GbE SFP+ ports (with one 10GbE SFP+/RJ45 
combo port) and eight Gigabit ports. QSW-308-1C is compatible with 10GbE and 
NBASE-T technologies to support five speeds (10G / 5G / 2.5G / 1G / 100M). The 
SFP+/RJ45 (copper) combo port offers higher transmission speeds when used with 
existing cables.

The unique fanless design with ventilated construction provides silent 
operations while maintaining high performance.

Simply connect the QSW-308-1C to your devices and it will do the rest. It 
supports auto-negotiation for optimal speed and duplex detection when connecting 
different devices.
Flexible deployment with multiple 10G SFP+ fiber and Gigabit 
ports
The QSW-308-1C provides three 10GbE SFP+ ports and eight Gigabit ports for 
connecting various devices and enabling a hybrid high-speed network in homes and 
offices. With SFP+ interfaces, direct attach copper (DAC) cables can be used for 
connecting directly to SFP+ devices. You can also use 10G-SFP-T copper 
transceiver modules to connect 10GBASE-T/NBASE-T devices through RJ45 Category 
6, 5 or 5e cabling. The switching capacity of QSW-308-1C is 76Gbps, guaranteeing 
the full potential of each port.

Faster speeds using existing cables with 10GBASE-T & 
NBASE-T
The QSW-308-1C is compatible with 10GbE and NBASE-T technologies to support 
up to five speeds (10G / 5G / 2.5G / 1G / 100M). The SFP+/RJ45 (copper) combo 
port offers higher transmission speeds with existing cables. Depending on cable 
types and their lengths, different speeds can be achieved for faster, more 
efficient data transfer.

Improve your productivity with a 10GbE-enabled QNAP NAS
Many QNAP NAS series are designed with 10GbE readiness, and can be 
immediately upgraded by purchasing and installing a 10GbE network adapter. QNAP 
NAS are also available with 10GbE SFP+ and 10GBASE-T as standard to fully 
support 10GbE high-speed networks, making them beneficial for IOPS-demanding 
applications such as virtualization, databases, high-resolution video editing, 
and sharing workflows.
Easily build a High-Speed Network with QNAP Network Expansion Cards 
and Network Adapters
QNAP provides a wide range of network devices to assist business and home 
users with upgrading their network infrastructure to meet growing bandwidth 
requirements. QNAP 10GbE Network Expansion Cards, Thunderbolt 3 to 10GbE Network 
Adapters and USB 3.0 to 5GbE Network Adapters can all be used with the 
QSW-308-1C to create a complete high-speed network environment for boosting the 
performance of photo/video editing, virtualization, large-file data transfers, 
and other bandwidth-demanding tasks.

Cool and quiet operation
The QSW-308-1C features a fanless design for silent operations. The unique 
ventilated construction assists in cooling while maintaining high 
performance.

Desktop size for easy use in homes and offices
With a compact and modern design, the QSW-308-1C fits perfectly alongside 
other devices in modern digital homes and offices. Featuring a delicate white 
polished or textured surface design, the QSW-308-1C helps users to easily 
identify each port. The flexible DC power connector also assists in universally 
deploying the QSW-308-1C.
