What is SFP+ Transceiver?

Definition of SFP+ SFP+ is a next-generation, hot-pluggable, small-footprint, serial-to-serial, multi-rate optical transceiver that commonly used in 8.5GbE to 11GbE data communications and storage-area network (SAN). It is a variant of the conventional SFP optical transceiver with enhancement interface defined in SFF-8074i, SFP+ with a similar size of SFP and compliant [ Continue reading…]

Guide to SFP+ Transceiver For 10 Gigabit Ethernet

by www.fiber-mart.com Introduction to SFP+ transceiver The small form-factor pluggable plus (SFP+) transceiver is based on SFP and developed by the ANSI T11 fibre channel group. SFP+ has become the most popular socket on 10GE systems due to its smaller size and lower power. SFP+ modules can further be grouped [ Continue reading…]

OTDRs Never Go Out of Style

by www.fiber-mart.com The optical time domain reflectometer (OTDR) is now thirty-six years old and aging gracefully. While fiber optic cables had been installed in North America since 1977, one major concern was and still is: how do we accurately locate a fault? This is the major reason that OTDRs exist. [ Continue reading…]

Don’t Tell Us Connector Cleaning Does not Matter!

by www.fiber-mart.com A high-performance fiber optic network requires low attenuation and low reflectance values to obtain the necessary bit error rate level. Unfortunately, all it takes is one contaminated or damaged connector to slow down or disrupt a transmission system. In the images below, see how cleaning connectors significantly reduces insertion loss [ Continue reading…]

Test Cables Don’t Last Forever

by www.fiber-mart.com I frequently hear customers complain that although nothing has changed in their fiber optic cable assembly production process, the measured Insertion Loss (IL) and Return Loss (RL) values of their product aren’t as good as they once were. Is something wrong with the measurement equipment? Well, it’s possible but unlikely. [ Continue reading…]

Fiber Optic Tap Couplers for FTTx Systems

by www.fiber-mart.com Maximizing the efficiency of optical line terminal (OLT) cards in passive optical networks (PON) in low-density and rural FTTx installations can be a major challenge. In most PON designs, it is considered ideal to connect 32 subscribers to a single OLT for maximum cost efficiency. In rural installations, [ Continue reading…]

Fiber’s Advantages over Copper

by www.fiber-mart.com All modern communications systems are based on fiber optic cable – hair-thin (or thinner) strands of glass that carry information by transmitting pulses of light, which are usually created by lasers. The pulses are turned on and off very, very quickly. A single fiber can carry multiple streams of information [ Continue reading…]

A Primer on Optical Amplifiers

by www.fiber-mart.com Attenuation is major concern in every fiber optic system. The further a digital signal travels, the more its strength diminishes. Every splice, every connector, and even the fiber itself will contribute a tiny bit more to the overall system loss. Fortunately, for spans that are too long or have [ Continue reading…]

Introduction of Fiber Optic Coupler with its Benefits & Classification

by Fiber-MART.COM A fiber optic coupler is an indispensable part of the world of electrical devices. Without these no signals would be transmitted or converted from inputs to outputs. This is the reason these are so important thereby this article discussed about these, introduction, classification and benefits in detail.   [ Continue reading…]
