Optical Gigabit Ethernet Interface Option Example
Figure 4‐17 depicts a CDM‐750 1:1 modem configuration using the FAST‐activated J7 Optical SFP
port and optional Optical Gigabit Ethernet Interface module (CEFD P/N IC‐0000058).
Depending on the mode – Single Mode or Multi Mode – installation involves use of either one
CA‐0000560 Optical Single‐Mode Y‐Cable set, or one CA‐0000559 Multi‐Mode Y‐Cable set. Mode
configuration is easily distinguished by the color of the cables; for Single‐Mode configurations,
yellow cabling is used by the CA‐0000560 'Y' Cable, whereas a Multi‐Mode configuration using
the CA‐0000559 'Y' Cable features orange cabling.
Type LC sockets, part of optional IC-0000058 SFP Module,
typical for Single-Mode or Multi-Mode Optical Gigabit Ethernet:
