Overview
A transceiver module converts electrical data signals to laser light, which is then transmitted over an
optical fiber. It can transmit optical signals over long distance with low signal loss. H3C devices
support many types of transceiver modules in different specifications.
H3C fiber network cables are Active Optical Cables (AOCs) terminated with transceiver modules.
H3C copper network cables include Active Copper Cables (ACCs) and Direct Attach Cables (DACs),
which are coaxial cables terminated with transceiver modules. Fiber and copper network cables are
collectively referred to as "network cable" in this document.
H3C devices support the following transceiver modules and network cables:
•
Transceiver modules
—QSFP-DD, QSFP28, CFP, CFP2, CXP, QSFP+, SFP28, SFP+, XFP,
and SFP transceiver modules.
•
Fiber network cables
—QSFP-DD, QSFP28, CXP, QSFP+, SFP28, and SFP+ fiber network
cables.
•
Copper network cables
—QSFP-DD, QSFP28, QSFP28 to SFP28, QSFP+, QSFP+ to SFP+,
SFP28, SFP+, CX4, and GE SFP copper network cables.
NOTE:
•
The available transceiver modules and network cables vary by device model. For transceiver
modules and network cables available for an H3C device, see the installation guide for the
product.
•
H3C transceiver modules and network cables are subject to change over time. For the most
recent list of H3C transceiver modules and network cables, contact H3C Support or marketing
