Overview of 100G QSFP28 Optical Transceivers

by www.fiber-mart.com QSFP28 fiber optic module has become the dominant form factor for 100G high-speed networks. The interconnect offers multiple channels of high-speed differential signals with data rates ranging from 25Gbps up to potentially 40Gbps, and meets 100Gbps Ethernet (4×25Gbps) and 100Gbps 4X InfiniBand Enhanced Data Rate (EDR) requirements. TARLUZ 100G [ Continue reading…]

When should i use OM5 Fiber

by www.fiber-mart.com The need to sort through these permutations may partially explain the reportedly low number of OM5 deployments so far. Even cabling suppliers with OM5 in their portfolios note that most 40 and 100 Gigabit Ethernet links are likely to fall within the reach of OM4, making the extended [ Continue reading…]

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…]

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…]
