Installation Instructions

The optical routing system supports both ring and point-to-point configurations. The optical routing
system includes the following parts:
• CWDM SFPs
• Optical add/drop multiplexers (OADM)
• Optical multiplexer/demultiplexers (OMUX)
• Optical shelf to house the multiplexers
OADMs drop or add a single wavelength from or to an optical fiber.

Supported optical devices
Use optical devices to achieve high-bit-rate communications and long transmission distances.
Important:
Extreme Networks recommends using the transceivers documented in this document as they
have been through extensive qualification and testing. Extreme Networks is not responsible for
issues related to third party transceivers.
You can use various transceivers to attain different line rates and reaches.
Small Form Factor Pluggable (SFP) transceivers
SFPs are hot-swappable I/O enhancement components designed to allow Gigabit Ethernet ports to
link with other Gigabit Ethernet ports over various media types.
Important:
The attainable cable length can vary depending on the quality of the fiber-optic cable used.
For more information about SFP transceivers, including technical specifications and installation
instructions, see SFP on page 23.
Small Form Factor Pluggable plus (SFP+) transceivers
SFP+ transceivers are hot-swappable I/O enhancement components that allow 10 Gigabit
connections. All branded SFP+ transceivers use LC connectors to provide precision keying and low
interface losses.
For more information about SFP+ transceivers, including technical specifications and installation
instructions, see
SFP+ on page 34.
Quad (4-channel) Small Form Factor Pluggable plus (QSFP+)
QSFP+ transceivers are hot-swappable data I/O components that allow 40 Gigabit Ethernet ports to
link with other 40 Gigabit Ethernet ports. All branded QSFP+ transceivers use LC connectors and
MPO/MTP connectors to provide precision keying and low interface losses.
For more information about QSFP+ transceivers, see
QSFP+ on page 50.
