Cable and Optic Specifications

The fiber optic cable physical characteristics must meet or exceed IEEE 802.3ae specification.

The optics specs depend on the SFP used. See the related SFP documentation for details.

• Straight-through or crossover twisted-pair cable may be used.
• Shielded (STP) or unshielded (UTP) twisted-pair cable may be used.
• Pins 1&2 and 3&6 are the two active pairs in an Ethernet network.
• Use only dedicated wire pairs for the active pins:
(e.g., blue/white & white/blue, orange/white & white/orange, etc.)
• Do not use flat or silver satin wire.
Category 5e: The category 5e specification improves on the category 5 specification by tightening some
crosstalk specifications and introducing new crosstalk specifications that were not present in the original
category 5 specification. The bandwidth of category 5 and 5e is the same (100 MHz) and the physical
cable construction is the same, and the reality is that most Cat5 cable meets Cat5e specifications, though
it is not tested or certified as such. The cable standard provides performance of up to 100 MHz and is
suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet).
10BASE-T and 100BASE-TX Ethernet connections require two wire pairs.
1000BASE-T Ethernet connections require four wire pairs. Cat 5e is the minimum for 1000 Mbps.
Category 6 cable, commonly referred to as Cat 6, is a standardized cable for Gigabit Ethernet and other
network physical layers that is backward compatible with the Category 5/5e and Category 3 cable
standards. Compared to Cat 5 and Cat 5e, Cat 6 provides more stringent specifications for crosstalk and
system noise. The Cat 6 cable standard provides performance of up to 250 MHz and is suitable for
