The 50 foot rule you refer to comes from the NEC Article 800.50 FPN No.2. You really have only two options: 1. Install metal condiut up to the 5th floor or 2. Terminate that 100-pair at the point of entrance, add primary protection and then extend that 100-pair to the 5th floor. However, if...

jward, To verify if the fiber strands in question meet expectations (if greater than 90 meters), I would suggest to measure the loss of the strands with a fiber light source and power meter. Use the below formula to determine if the loss you are reading is acceptable per the ANSI/TIA/EIA-568B.2...

Avaya- Thanks for navigating me back to the point! Cat 5 vs. Cat 5e: Cat 5 = 100Mhz, 1000BaseT not guaranteed Cat 5e - 100Mhz, 1000BaseT Guaranteed! As Daron stated you need to feel out what the customer wants to do now and in the future. Cat 6 may also be on the table. Humbly... Doug...

My point is this, for example, if the customer wants to lease a Toyota for 3 years and you can give that customer a 10-year lease on a BMW for the exact same cost. Which would you choose? If the customer knows he has too options: 1. Spend 100K ($$example only) to replace cable with Cat 5 and...

Folks, The bottom line is if you can give me, the customer, a standards compliant, Gigabit Ethernet guaranteed, category 5e solution at basically the same cost versus cat 5, Gigabit Ethernet not guaranteed, system that is not recognized by the standards, then you have earned my business. I, the...

nelsonvelez, You can start by informing your customer that category 5 is no longer a recognized cable by TIA or ISO/IEC. With the release of ANSI/TIA/EIA-568-B.1 Commercial Building Telecommunications Cabling Standard - Part 1: General Requirements, category 5 does have the necessary electrical...

Daron- You're correct. I should have stated that it "may cause packet loss". Just trying to address any folks who have tested their 4-connector links to cat 5e/6 specifications after the initial install who have very little margin to begin with. They then introduce solid patch cords...

One aspect that has not been addressed specifically...cable bend radius! The ANSI/TIA/EIA-568-B.1 Addendum 1 Minimum 4-pair UTP and 4-pair ScTP Patch Cable Bend Radius, states... "The minimum inside bend radius, under no load conditions, for 4-pair UTP patch cable shall be 6 mm (0.25 in)...
