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 […]
OTDR used in Fiber Optic Network Acceptance testing – 1
OTDR used in Fiber Optic Acceptance testing – 1 Fiber optic acceptance testing ensures that any new cable matches the optical and physical requirements of the planned application. This testing should be performed upon delivery of the cable, prior to its installation. It is important that the operator knows the specifications in order to properly […]
What is Fiber Testing
What is Fiber Testing Why Fiber Testing is important? Fiber optics cabling is the core of today’s Datacom/FTTH/CATV/ networks. Optical fiber is the currently predominant media type for mission-critical datacenter links, backbone within buildings, and longer distances for campus networks. As network speeds and bandwidth demands increase, distance and loss limitations have decreased, making fiber optic […]
