HOW To choose the right fiber optic cable for your fiber optic network? Background of fibe roptic nework The fundamental difference between a fiber optic communication system and other types is that signals are transmitted as light. Conventional electronic communication relies on electrons passing through cables. Microwave communication relies on microwaves travelling through open space. […]

40G, 100G, 400G is not far
Is it possible to think of something without knowing a word to describe it ? According to some studies, humans understand the concept of numbers and counting before knowing the words for those numbers. Perhaps that means that this month’s blog will be easier for everyone to understand, since I’ve found that it’s hard to […]
OFC – 2015
Technical Conference: 22-26 March 2015 Exposition: 24-26 March 2015 Los Angeles Convention Center, Los Angeles, California, USA OFC—A Dynamic Global Gathering OFC is the largest global conference and exposition for optical communications and networking professionals. For over 40 years, The Optical Fiber Communication Conference and Exposition (OFC) has drawn attendees from all corners of the […]
Hybrid GPON/G.fast distribution point unveiled by Telnet Redes Inteligentes
Telnet Redes Inteligentes S. A. has introduced a Hybrid Fiber-Copper Access Distribution Point (HFCA-DP). The platform is the first to combine GPON and G.fast distribution point equipment (DPE) capabilities in a manner fully interoperable with Alcatel Lucent and Huawei GPON optical line terminals (OLTs), the company asserts. The DPE also can be used in WDM-PON […]
Optical Fiber FAQ
Optical Fiber FAQ (Frequent Asked Question) Optical Fiber FAQ 1: What is optical fiber? A: Optical fiber is a glass or plastic filament that guides a light wave along its path. In another terms, fiber optics is a medium for carrying information from one point to another in the form of light. Unlike the copper […]
Fusion Splicing FAQ
Fusion Splicing FAQ, Updating Fusion Splicing FAQ 1: What is Fiber Splicing? A: Fiber Splicing is used to permanently join two optical fibers where no additional changes are expected to be made to those fibers at that juncture. This is in contrast to connectors, which are designed to allow quick re-configuration of fiber links. There […]
GPON GEPON Comprehensive Comparison
Initial PON (1990s) were based on ATM framing (APON, BPON), ATM-based BPON were inefficient, majority of traffic through the access network was IP traffic, Ethernet based PON (EPON), QOS-aware Gigabit Ethernet (GbE) (VLANs, prioritization, OAM) and integration with other Ethernet equipment, Gigabit-capable Passive Optical Network (GPON) proposed by FSAN members (Quantum Bridge et. al) – […]
OTDR FAQ – 1
OTDR FAQ Gathering AFL Global OTDR FAQ OTDR FAQ 1: When do I need to use a launch cord (cable) with my OTDR? A: A launch cord ‘moves’ the effects of the OTDR’s own front panel connection away from the first connection in the link under test. This allows the OTDR to measure the loss […]
Glossary – A
Glossary start with Letter A: Abrasion resistance The surface ware resistance of the fiber optic cable. Absorption Caused by impurities introduced during the manufacturing process, absorption creates loss in a fiber by turning light energy into heat. The amount of absorption is determined by the wavelength and depends upon the composition of the glass or plastic. […]
OTDR used in Fiber Optic Network Acceptance testing – 2
OTDR used in fiber network acceptance test We will use the manual method of OTDR operation. Start the OTDR and select the correct wavelength and refractive index for the test. Set the OTDR’s measurement mode to “Two Point Attenuation”. In this mode, the OTDR allows you to set markers at any two points on the backscatter […]
