WCS-2 and WCS-4 Subrack Overview
Optical Transport (OPT) Card
The OPT Card (PN 7642123-xx) provides a 10 Gbps fiber connection between CANs, TENs, and WINs; and
between CANs and TENs and Fiber APs. If a CAN requires that Slots L1 - L8 all have an OPT Card installed to
support a full complement of TENs, you must use the TENs to connect the APs. CommScope R&D has updated
the (7642123-00) OPT Card with new subcomponents to prevent material delays. The new (7642123-01)
OPT Card has the same the form, fit, function, and performance as the previous card. Both versions of the card
can work in the same system, but the 7642123-01 card requires ERA system software V2.8.0 or higher.
• For rules on where an OPT Card is installed in a WCS Subrack, see "WCS Subrack Slot and Card
Assignments” on page 17.
• For rules that apply to OPT Cards and cascading Fiber CAP Ls, CAP Ms, or CAP Hs, refer to the Fiber
CAP Ls, CAP M, and CAP H installation guides; see "Accessing ERA Series User Documentation” on page 83.
The following graphic and table identify the OPT Card connectors and LED.
OPT Card SFP Connectors

Ref # LED LED Color Description
2 1 - 4
• Off
• The OPT Card has no power, or the OPT Card is plugged into the wrong
Subrack slot (see "WCS Subrack Slot and Card Assignments” on page 17).
• Green • Optical link is established with device to which the port is connected.
• Yellow
• The OPT Card is powered and initialized, but the link with the
corresponding SFP port is not established. Problems that can activate the
yellow LED include but are not limited to the following: an issue with the
