Optical Distribution System Architecture: Interconnect

When configuring an Optical Distribution Frame (ODF), one of the first considerations is the decision between interconnect and cross-connect architectures. As with the location of optical components, this decision has large implications for the network’s future growth, reconfigurability, cost and reliability. Interconnect Systems Architectures Interconnect involves the OSP cable being spliced to a pre-connectorized pigtail, […]

Functional Requirements Of A Fiber Distribution System: Splicing

Splicing: Splicing in fiber optics is the physical joining of two separate optical fibers with the goal of having 100-percent signal transfer. Splicing connections are meant to be permanent, non-reconfigurable connections. There are two basic splicing methods in use today: mechanical and fusion (see Figure 1) below: [figure 1] Mechanical Splicing Mechanical splicing involves the […]

The Importance of a Slack Storage System For Network Reliability

Overcoming Cable Management Problems with Storage: Most ODF systems encounter cable management problems in the storage of excess fiber cable. Since most singlemode connectors today are factory-terminated to a patch cord of a predetermined length, there is always some excess fiber remaining after the connections have been made. At some point during the life of […]

Fiber Distribution Management System: Terminations

‘Connection determined by quality’ Let’s return now to the four basic functional requirements of any fiber distribution management system: terminations, splicing, slack storage, and housing of passive optical components. In order for the signal to get from one fiber to another, the cores of the two fibers need to be joined, and brought into near-perfect […]

Cable Management: Routing Paths, Access and Physical Fiber Protection

This blog post is going to talk about these three critical elements of fiber cable management; cable routing paths, cable access, physical protection. All aspects directly affect the network’s reliability, functionality, and operational cost. We explored the fourth critical element of fiber cable management; bend radius protection in our previous blog post. Cable Routing Paths […]

Fiber Optic Bend Radius Protection: A Critical Element of Fiber Cable Management

There are four critical elements of fiber cable management: bend radius protection; cable routing paths; cable access; physical protection. All four aspects directly affect the network’s reliability, functionality, and operational cost. This blog post is going to talk about the importance of bend radius protection. Fiber Optic Bend Radius Protection There are two basic types […]

Glossary of RF Path Terms

We’ve put together a blog post compiling a RF path glossary with a list of terms that are commonly used in radio frequency applications. Alternating Current (AC) An electrical current that changes polarity (i.e., direction) 50 to 60 times per second. It offers significant efficiencies when transmitted across power lines, making it the standard current […]

Maximizing Capacity With Microwave Backhaul

Network capacity and managing demand Simply put, capacity is a network’s ability to handle transmission traffic. In the case of cell communications, this traffic means voice and data – often, a great deal of data. As capacity demands continue to rise with the spread of long-term evolution (LTE) and 4G mobile devices, smart planning becomes […]

Interference Isolation Techniques for Transmitters and Receivers in Antenna Systems

Achieving sufficient isolation The correct degree of isolation between transmitters and receivers can be implemented by one of two methods: 1) Use two antennas, physically separated by a given distance, or; 2) Use the appropriate duplexer with a single-antenna system. Let’s examine the first option of two physically separated antennas. Within this option, there are […]
