PCIe2 8 Gb 2-Port Fibre Channel Adapter (FC EN0F and EN0G; CCIN 578D)

Overview

FC EN0F and EN0G are both the same adapter with different feature codes. FC EN0F is a low-profile adapter and FC EN0G is a full-height adapter.

The PCIe2 8 Gb 2-port Fibre Channel Adapter is a PCI Express (PCIe) generation 2 (Gen2), high-performance, x8 short form factor pluggable plus (SFP+) Host Bus. This adapter enables multiple logical (virtual) connections to share the same physical port. Each logical connection has its own resources and the ability to be managed independently. Each port provides single initiator capability over a fiber link or provides multiple initiator capability with N_Port ID Virtualization (NPIV). The ports are connected by using LC type connectors. These connectors use shortwave laser optics. The adapter operates at link speeds of 2, 4, and 8 gigabits per second (Gbps) and automatically negotiates to the highest speed possible. LEDs on each port provide information about the connection status and link speed of the port. The adapter connects to a Fibre Channel switch.

Cables

Cables are the responsibility of the customer.

Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:

• OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
• OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth

Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best results, OM2 cables should not be connected to OM3 cables. However, if an OM2 cable is connected to an OM3 cable, the characteristics of the OM2 cable apply to the entire length of the cables. The following table shows the supported distances for the different fiber optic cable types at different link speeds.
