SFP Module
The SFP (Small Form Factor Pluggable) module converts optical data into electrical data and
vice versa. The SFP modules allow the NSG to receive input signals over a variety of physical
interfaces:
Single-mode optical interface (1000 Base-LX)
Multi-mode optical interface (1000 Base-SX)
Copper interface (1000 Base-T)
The following figure illustrates an SFP module:
Warning:
Class I laser product. (IEC/EN 60825-1; 21CFR SubChapter J (1040.10 and
1040.11)
You can use either of the following types of SFP depending on the cable/fiber type you are
using.
Harmonic sells SFP modules that have been thoroughly qualified to operate with the NSG
9000 device. These SFPs are made by Finisar, and may be purchased either directly from
Harmonic, or from other sources.
Table 1-11
on page 17 lists the Harmonic part numbers for the qualified SFP modules, as well
as the matching Finisar part numbers for the same modules. Use these part numbers for
ordering your SFP modules.
