Zone Cabling is a generic term that means different things to different people. To some, it means an “active consolidation point (CP)” or an “active Multi-User Telecommunications Outlets Assembly (MUTOA)” since the CP and MUTOA are covered in the “zone” clauses of the Pathways & Spaces Standard, TIA-569B. However, active devices in the “zone” are beyond the scope of TIA-568B, Commercial Building Cabling.

While there has been some “buzz” about Optical Time Domain Reflectometer(OTDR)testing for premises cabling since the publication of TSB-140, Additional Guidelines for Field-Testing Length, Loss and Polarity of Optical Fiber Cabling Systems, many agree that the test is usually not necessary for the relatively short links found in a customer-owned network, and may merely add unnecessary expense and complexity. When testing an optical premises network, the key measurement criterion is insertion loss, or attenuation. This is effectively measured by using a power meter and light source. If the attenuation is within the limits of the allotted power budget, the system

Companies that are installing fiber today should consider the new 50-micron laser-optimized multimode fiber as it will fully support 10 Mbps or 100 Mb/s legacy applications as well as provide 1 and 10 Gb/s future-proofing. In addition, laser optimized 50-micron multimode fiber supports low-cost multimode opto-electronics and low-cost, easy-to-install connectors. However, if your company already has 62.5 micron or standard 50-micron installed in its network there’s no need to panic — or to pull out the fiber and recable. Both of these fiber types offer the ability to support application up to Gigabit levels and are likely to meet your

Corning CamSplice single mode mechanical splice features a patented “cam” fiber locking mechanism and requires no adhesive. The “cam” fiber alignment method self-centers the fibers and provides high precision alignment. The average loss for the CamSplice mechanical splice is about 0.15dB with a maximum loss at 0.3dB. One single part works for 250um/250um, 250um/900um and 900um/900um mechanical splice applications. Assembly process for the CamSplice single mode mechanical splice Strip the fibers Cleave the fibers Insert the fibers in the splice until they touch Turn the cams to lock the fibers The CamSplice single mode mechanical splice requires no adhesive and special tools.

As transmission moves closer to the user and distances become shorter, a set of solutions are necessary to address the specific needs of the LAN market and those of other short-reach applications, such as SAN (storage area network) and equipment room interconnections. Also the demand for data rates in excess of a Gbps keeps growing for the above applications, so multimode fiber and short-wave VCSELs are becoming the dominant technologies. Since the success of 100Mbs fast ethernet in the 1990s, the driving forces behind the spurring interest in multimode fibers are the Gigabit Ethernet and 10Gigabit Ethernet. Although other technologies
