Role of Optical Fiber in Short Distance Communication
>> Origin of Optical Fiber This idea is very simple. Let us fill up a container with water and shone a light into it. In a darkened room, then pull out the bung. The light shone out of the hole and the water gushed out. It is expected that the light would shine straight out of the hole and the water would curve downwards, as in the diagram. But the light stayed inside the water column and follows the curved path. Nature had found a way to guide light. What was expected and what actually happened here lead to the

BPON vs GPON vs EPON – A Comparison of BPON GPON and EPON
Both BPON and GPON architectures were conceived by the FSAN group, which is driven by major incumbent telecommunications operators. Most of the operators are heavily invested in providing legacy TDM services. Accordingly, both BPON and GPON are optimized for TDM traffic and rely on framing structures with a very strict timing and synchronization requirements. In BPON, an upstream frame consists of 53 timeslots, where each timeslot is comprised of one ATM cell and 3 bytes of overhead. When two consecutive timeslots are given to different ONUs, these 3 bytes or approximately 154 ns of the overhead should be sufficient to

Fiber Optic Benefits and Fiber Optic Advantages
Fiber-optic systems use pulses of light traveling through an optical fiber to transmit data. This method offers many advantages over copper wire, some of which are not available with other technology: Complete input/output electrical isolation No electromagnetic interference (EMI) susceptibility or radiation along the transmission media Broad bandwidth over a long distance Light-weight, small-diameter cables Equal to the cost of copper wire and connectors (except when copper wire is already installed) So let’s explain the fiber optic benefits and advantages in detail below: 1. Electromagnetic Interference (EMI) Because optical fiber transmits light rather than electrons, it neither radiates EM (electromagnetic)

10 Gigabit Ethernet Overview
The ink was hardly dry on the 10Gbase-T (10 gigabit Ethernet over UTP) standard and the industry discussion swung to the next big thing – 40 Gigabit and 100 Gigabit Ethernet. While the latest technology being developed always makes for interesting discussion, it is the deployable technology that exists today that receives the most day-to-day conversation. To that end, we are only just beginning to see 10 gigabit Ethernet actually being deployed in local area network (LAN) environments. The IEEE standards organization recently ratified the IEEE802.3an-2006 reference standard defining 10GBase-T allowing for 10 gigabits per second data transmission over Category-6a

3M Fibrlok 2540G 250-micron fiber splicing tool
The 3M Fibrlok 2540G fiber splice tool is designed to enable fast, easy splicing of 250-micron singlemode fiber in FTTP installations and in multimode enterprise installations. The Fibrlok 250um fiber splice is designed to be installed at the drop in fiber distribution terminals and optical network terminals outside and at fiber distribution units and wall outlets indoors. According to the company, the low-loss splice provided by the tool can be installed with little or no training by nonspecialized technicians working inside buildings or outdoors. With the tool, several crews can be equipped for less than the cost of a single
