Understand 100G Transceivers Transmission Principles

Changes to transmission speeds and expansion in data center capacities have driven the 100 Gigabit Ethernet. IHS Infonetics reports that by 2019, 100G Ethernet will make up more than 50 percent of data center optical transceiver transmissions. For 100G transceivers, there are 100GBASE-SR4, SR10 and PSM4 for short-distance transmission and [ Continue reading…]

Basic Principle of OTDR Test

There are many fiber tools available for testing at different stages of the network, to meet various test requirements. These tests are used to reveal the total loss, optical return loss (ORL) and fiber length, can be in a single fiber or a complete network. In addition, the test may [ Continue reading…]

Why Use The Specific In-service Portable OTDR Device?

In order to troubleshoot PON networks in service, two dedicated tools are available — PON power meter and In-service 1625 or 1650 nm OTDR. As we know, a PON power meter is normally employed to verify that the signal is transmitted correctly to and from the ONT. A PON meter measures the [ Continue reading…]

Should We Choose Punch Down or Feed-through Patch Panel?

Copper patch panels provide a useful solution for cable management in data centers and other high-density environments. In the market, two types are offered like punch down and feed-through categories. But consumers often find it’s difficult to make a decision on which one is better. This article is going to help [ Continue reading…]

OFNP, OFNR, OFNG: Which to Use?

Optical Cable Fire Rating Comparison Typically, there are four levels of fire resistance for both non-conductive and conductive cables. The fire resistance levels are outlined below from most stringent to least. The ratings are hierarchical, i.e., from a fire resistance standpoint, a higher rating can be substituted for any lower [ Continue reading…]

How to Install CWDM MUX/DEMUX System?

Coarse wavelength division multiplexing (CWDM) technology is developed to expand the capacity of a fiber optic network without requiring additional fiber. In a CWDM system, CWDM Mux/Demux (multiplexer/demultiplexer) is the most important component. Usually, a CWDM Mux/Demux is used to increase the current fiber cable capacity by transmitting multiple wavelengths, typically up to [ Continue reading…]

Fujikura Fusion Splicer Solutions

Fiber optic cables provide a reliable and fast method of data transfer. However, it’s simply impossible to make a single fiber long enough to match the length of cable necessary for most networks. This is where fiber fusion splicing comes into play, which is a technique of making fiber joints by fusing fiber [ Continue reading…]
