Hca3-O (12X Ifb) Fanout (Fc 0171); Om3 50/125 Μm Multimode Fiber Cable With Mpo Connectors - IBM z13s Technical Manual

The ICA SR can be used only for coupling connectivity between z13 and z13s servers. It does
not support connectivity to zEC12, zBC12, z196, or z114 servers, and it cannot be connected
to HCA3-O or HCA3-O LR coupling fanouts.
The ICA SR fanout requires new cabling that is different from the 12x IFB cables. For
distances up to 100 m, clients can choose the OM3 fiber optic cable. For distances up to
150 m, clients must choose the OM4 fiber optic cable. For more information, see z Systems

4.6.4 HCA3-O (12x IFB) fanout (FC 0171)

The HCA3-O fanout for 12x InfiniBand provides an optical interface that is used for coupling
links. The two ports on the fanout are dedicated to coupling links that connect to z13, z13s,
zEC12, zBC12, z196, and z114 CPCs. Up to 8 HCA3-O (12x IFB) fanouts are supported, and
provide up to 16 ports for coupling links.
The fiber optic cables are industry standard OM3 (2000 MHz-km) 50-µm multimode optical
cables with MPO connectors. The maximum cable length is 150 meters (492 ft.). There are
12 pairs of fibers: 12 fibers for transmitting and 12 fibers for receiving. The HCA3-O (12xIFB)
fanout supports a link data rate of 6 GBps.
Important: The HCA3-O fanout has two ports (1 and 2). Each port has one connector for
transmitting (TX) and one connector for receiving (RX). Ensure that you use the correct
cables. An example is shown in Figure 4-7.

A fanout has two ports for optical link connections, and supports up to 16 CHPIDs across
both ports. These CHPIDs are defined as channel type CIB in the input/output configuration
