Splicing Connectors: On-Frame and Off-Frame

Splicing Connectors The splicing of outside plant (OSP) fibers to connectorized pigtails, to allow termination panel access to the OSP fiber, can be done in two basic configurations: on-frame and off-frame. On-Frame Splicing On-frame splicing (See figure 1) is performed within the confines of the optical distribution frame (ODF), whereas off-frame splicing is done away […]

Optical Distribution System Architecture: Cross-Connect

When configuring an optical distribution frame (ODF), one of the first considerations is the decision between interconnect and cross-connect systems. As with the location of optical components, this decision has large implications for the network’s future growth, reconfigurability, cost, and reliability. Cross-Connect Systems Architecture A cross-connect ODF architecture provides a dedicated termination point for both […]

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 […]
