The SFP/SFP+ modules (transceiver) convert electrical signaling coming from a network switch into light signaling to send down the fiber optic medium. The table below shows the various fiber SFP/SFP+ modules that Ubiquiti offers. 0.86 FC Multimode Connectors 0.86 Mini MM FC 900um Connector, Dome 2.13 LC Multimode Connectors, Duplex, 127um 2.62 MT-RJ Multimode Connectors, 127um ST Multimode Connectors 0.86 FC Multimode Connectors 0.86 SC Multimode Connectors 0. NOTE: *Green is used for angle polished fiber typically used in Passive Optical Networks (PON) such as UFiber GPON.Do not use angle polished fiber in a transceiver designed for 'physical contact' type fiber. This leads to a very small chance of signal degradation which allows for very large data transport distances. Opposed to Multi-Mode fiber optic cabling, Single-Mode has a much smaller core diameter which limits the width of the wavelength. Multi-Mode fiber allows for the use of lower-cost LEDs instead of lasers in the optical transceiver, leading to a cost reduction. The diameter of MM fiber optic cable is substantially larger allowing for wider wavelengths to pass down the cable. However, this limits the maximum length of transmission links possible due to modal dispersion. The key difference between Multi-Mode (MM) and Single-Mode (SM) fiber optic cable is the core diameter. Multimode fiber cables are the type of fiber cables that transmit data via their core of larger diameters enable an average, single-mode transceiver multiple modes of light to propagate through it. Posted: JCategories: fiber optic Tags: single mode, multimode, fiber optic Author: Nicholas Watkins For decades, all varieties of cables from coax to ethernet have used electrical signals to transmit signals through metal cores. For example, do not use a 50 micron path cable with 62.5 micron premises fiber. See the tables and sections below for more information.ĪTTENTION:It is important to never mix cable types. Depending on the cost of goods, the distance of the run, and throughput requirements one type of fiber optic cable and transceiver may be more effective than another. By using pulses of light, the distance over which signals can be sent is far greater than Ethernet (copper) cabling.įiber optic cable comes in various shapes and sizes which can be used for different types of deployments. Instead of using electrical pulses to transport information, fiber optic cable transports pulses of light that are sent and received by transceivers on each end of the cable. Table of Contentsįiber optic cabling is an alternative to copper cabling for data transmission. MMF Deployment Overview Laser-Optimized 50-m MultiMode Fiber (LOMMF) is the recommended fiber type in todays Local Area Network (LAN) and Data Center (DC) environments in conjunction with 850 nm vertical-cavity surface-emitting lasers (VCSELs). See the SFP/SFP+ Modules and Cabling page for more information. Ubiquiti also provides branded optic SFP/SFP+ modules (tranceivers) that are fully compatible with all of our devices. This article describes the common types of fiber optic cable used for data transmission.
