AFL rolls out OFI-BIPMe optical fiber identifier

AFL has unveiled its OFI-BIPMe, an optical fiber identifier technicians can use to determine if a fiber is live, the transmission direction, and the relative core power.
The OFI-BIPMe is a cousin to the previously introduced OFI-BIPM. It offers a lower price point for applications that do not require advanced PON functions such as the capability to detect ONTs.

Viavi unveils new optical fiber testing capabilities for PON, 5G and data center networks

Viavi introduced multiple new capabilities for its Optical Network Monitoring Solutions family of remote test and monitoring platforms. The company says the new capabilities enable further network intelligence in fiber environments that form the foundation of high-speed core and metro ring networks, as well as access applications in passive optical network (PON), 5G and data center networks.

Testing Vendor-Specified Channels

Wondering about standards compliance and testing requirements for extended-length twisted pair cabling? Sometimes there is pressure to connect a device beyond the guidance of the cabling standards. In an extended-reach channel, the installation will not be standards compliant. This may mean that the application support will be limited to certain data rates, certain cables and components, certain installation conditions, or is tied to certain types of network equipment. It could mean that the application support is not assured by the network equipment manufacturer, and instead falls to the cabling vendor. That might be just fine with your customer, but it’s best to make sure. You should educate them about the solution and the implications of non-standards compliant cabling. And just because something isn’t standards compliant, doesn’t mean you don’t have to test it.

Simple Rule for Cleaning Optical Fibers

The performance of a fiber optic system depends heavily on the cleanliness of the interfaces. Dirt particles, grease, dust, etc. can have a highly negative impact on the transmission characteristics. They can actually destroy a fiber optic connection depending on the circumstances. If the connector is plugged in without first being tested, it could well be too late. The high pressure in the connection means that particles are immediately pressed in and this causes irreversible damage. This is why it is becoming increasingly important to test all connectors and adapters, and, if necessary, to clean them before they are mated – even new products that have just come out of the packing.
