10-Gigabit Ethernet (10-GbE), ratified in June 2002, is a logical extension of previous Ethernet versions. 10-GbE was designed to make the transition from LANs to Wide Area Networks (WANs) and... more/see it nowMetropolitan Area Networks (MANs). It offers a cost-effective migration for high-performance and long-haul transmissions at up to 40 kilometers. Its most common application now is as a backbone for high-speed LANs, server farms, and campuses.
10-GbE supports existing Ethernet technologies. It uses the same layers (MAC, PHY, and PMD), and the same frame sizes and formats. But the IEEE 802.3ae spec defines two sets of physical interfaces: LAN (LAN PHY) and WAN (WAN PHY). The most notable difference between 10-GbE and previous Ethernets is that 10-GbE operates in full-duplex only and specifies fiber optic media.
At a glanceGigabit vs. 10-Gigabit Ethernet
• CSMA/CD + full-duplex
• Leveraged Fibre Channel PMDs
• Reused 8B/10B coding
• Optical/copper media
• Support LAN to 5 km
• Carrier extension
• Full-duplex only
• New optical PMDs
• New coding scheme 64B/66B
• Optical (developing copper)
• Support LAN to 40 km
• Throttle MAC speed for WAN
• Use SONET/SDH as Layer 1 transport
The alphabetical coding for 10-GbE is as follows:
S = 850 nm
L = 1310 nm
E = 1550 nm
X = 8B/10B signal encoding
R = 66B encoding
W = WIS interface (for use with SONET).

Black Box Explains... Coax cables for ServSwitch products.
Whats the difference between standard and coax cables for ServSwitch™ products? Performance! Coax cables are made with premium-gauge wire, so they can be made in longer lengths. That means you... more/see it nowcan move your workstation up to 100 feet (30.4 m) from your ServSwitch. Plus coax cables have even more shielding to maintain the signal quality and strength you need. If you require high-resolution video or long distances, this is the cable you need! collapse
Black Box Explains...Breakout-style cables.
With breakout- or fanout-style cables, the fibers are packaged individually. A breakout cable is basically several simplex cables bundled together in one jacket. Breakout cables are suitable for riser and... more/see it nowplenum applications, and conduit runs.
This differs from distribution-style cables where several tight-buffered fibers are bundled under the same jacket.
This design of the breakout cable adds strength to the cable, although that makes it larger and more expensive than distribution-style cables.
Because each fiber is individually reinforced, you can divide the cable into individual fiber lines. This enables quick connector termination, and eliminates the need for patch panels.
Breakout cable can also be more economical because it requires much less labor to terminate.
You may want to choose a cable that has more fibers than you actually need in case of breakage during termination or for future expansion. collapse
