Hi,
I am drafting a list of Network+ Lan technology types and their properties according to the CompTIA Net+ 2009 objectives.
Anyone got a moment and make suggestions on improving this?
The properties I would like to compare are CSMA/CD, Broadcast, Collision, Bonding, Speed and Distance.
Any thoughts?
Categorize LAN technology types and properties
10-Base-T
• 10Base-T
– 10 represents maximum throughput: 10 Mbps
– Base indicates baseband transmission
– T stands for twisted pair
– Two pairs of wires: transmit and receive
• Full-duplex transmission
– Follows 5-4-3 rule of networking
• Five network segments
• Four repeating devices
• Three populated segments maximum
100-Base-TX
- 100 represents maximum throughput: 100 Mbps
- Base indicates base band transmission
- T stands for twisted pair
X was a place holder they used when developing the standard that just stuck – it doesn’t mean anything.
- Maximum segment length is 100M
- Physical media is CAT5 (CAT5e) or higher UTP
100-Base-FX
• 100Base-FX (Fast Ethernet)
– 100-Mbps throughput, broadband, fiber-optic cabling
• Multimode fiber containing: at least two strands
– Half-duplex mode
• One strand receives, one strand transmits
• 412 meters segment length
– Full duplex-mode
• Both strands send and receive
• 2000 meters segment length
– One repeater maximum
– IEEE 802.3u standard
1000-Base-T
- 1000 represents maximum throughput: 1000 Mbps
- Base indicates base band transmission
- T stands for twisted pair
- Maximum Segment length is 100M
- Physical media is CAT5 (CAT5e) or higher UTP
1000-Base-X
10GBaseSR / / 10GBaseSW
• 10GBase-SR and 10GBase-SW
– 10G: 10 Gbps
– Base: baseband transmission
– S: short reach
– Physical layer encoding
• R works with LAN fiber connections
• W works with SONET fiber connections
– Multimode fiber: 850 nanometer signal transmission
– Maximum segment length
• Depends on fiber diameter
10GBaseLR
10GBase-LR and 10GBase-LW
– 10G: 10 Gbps
– Base: baseband transmission
– L: long reach
– Single-mode fiber: 1319 nanometer signal transmission
– Maximum segment length
• 10,000 meters
– 10GBase-LR: WAN or MAN
– 10GBase-LW: SONET WAN links
10GBaseER / 10GBaseEW
• 10GBase-ER and 10GBase-EW
– E: extended reach
– Single-mode fiber
• Transmit signals with 1550 nanometer wavelengths
– Longest fiber-optic segment reach
• 40,000 meters (25 miles)
– 10GBase-EW
• Encoding for SONET
– Best suited for WAN use
10GBaseLW
- 10G represents maximum throughput: 10000 Mbps
- Base indicates base band transmission
- Maximum segment length 10000M
- Physical media is single mode fibre
10GBaseT
- 10G represents maximum throughput: 10000 Mbps
- Base indicates base band transmission
- Maximum segment length 100M
- Physical media is Cat 6 or Cat 7 preferred
