Add a 100 Gigabit optical interface to a compatible Palo Alto network port while retaining duplex multimode-fiber cabling. eNet Components PAN-QSFP28-100GBASE-BIDI-ENC is a QSFP28 BiDi transceiver encoded for Palo Alto compatibility and specified for 100GBASE-SR functional operation. Its bidirectional optical design carries a 100G link over two fiber strands, rather than using the parallel-fiber path commonly associated with conventional short-reach 100G connections. Install the module in a compatible QSFP28 port and connect its duplex LC optical interface to multimode fiber. It fits switch-to-switch, switch-to-server, and aggregation links where an existing duplex multimode-fiber run must support 100 Gigabit Ethernet without changing the installed cable path to parallel fiber. Both ends of the link still require compatible 100GbE optics and multimode-fiber connectivity. This variant combines a QSFP28 form factor, 100GbE signaling, multimode BiDi optics, and Palo Alto-compatible encoding in one module. Select it when the endpoint platform requires that encoding and the physical link uses duplex multimode fiber. A QSFP28 mechanical fit alone does not establish platform recognition or optical-path compatibility; verify endpoint port support, fiber type, connector mating, and the required link architecture before installation.
