EXFO launches tunable CWDM OTDR modules

EXFO has launched the FTB-740C-CWDM, a tunable optical time domain reflectometer (OTDR) module designed for its handheld FTB-1 platform, which enables technicians to test all 18 ITU-defined CWDM channels without having to swap modules.

This capability will be speed up network testing for cable multiple-service operators (MSOs) and contractors, who will always have the CWDM wavelength required for characterising their network through multiplexers and demultiplexers (mux/demux).

EXFO launches FTB-4 Pro platform for all-in-one 100G test

EXFO has launched the FTB-4 Pro platform, which it claims is the industry's smallest platform for testing high-speed optical networks.

The FTB-4 Pro is the latest addition to EXFO's modular test portfolio. It supports a wide range of modules across a wide range of test scenarios, from lab applications to field testing across all phases of the service delivery chain: development, deployment, maintenance and troubleshooting.

EXFO offers OSA designed for network equipment manufacturers

The new FTBx-5245 Series of optical spectrum analysers (OSAs) from EXFO are dedicated to R&D labs and manufacturing. Faced with today’s unprecedented transformation challenges, network equipment manufacturers (NEMs) must innovate faster while managing costs and remaining agile in their production processes. The versatile form factor of the FTBx-5245 Series maximises return on investment for NEMs, according to EXFO.

EXFO adds Ookla’s Speedtest technology to MaxTester 635G

Test and measurement specialist EXFO has added Speedtest by Ookla's technology to its MaxTester 635G tester, giving service providers a single tool that integrates physical, service and throughput testing.

Introduced last year, MaxTester 635G is a handheld G.fast test set and has already been selected by Openreach for its G.fast roll-out (see EXFO MaxTester 635G selected for Openreach G.fast pilot).

iLOOP function from EXFO reduces OTDR test time

The new intelligent loopback feature for EXFO’s intelligent Optical Link Mapper (iOLM) application is designed to simplify optical time-domain reflectometer (OTDR) testing by allowing two fibres to be characterised at once.

This doubles test efficiency, resulting in time spent on testing and analysis being slashed by at least 50 per cent, the company claims. Cutting fibre-testing time in half amounts to substantial opex savings - a key consideration for operators.

EXFO enhances CPRI test capabilities

EXFO has added an enhanced common public radio interface (CPRI) protocol test functionality to its all-in-one Ethernet/optical FTB-700G series and FTB-800 NetBlazer series of portable field testers.

This latest feature gives field technicians the capability to install and maintain mobile fronthaul networks by testing connectivity and data integrity between the remote radio head (RRH) and baseband unit (BBU) in new fibre-fed cell towers.

40G/100G OSNR Measurements with a Pol-Mux OSA

In order to meet the constantly increasing need for bandwidth, more and more telecommunications operators are now deploying 40G or 100G coherent systems on long-haul dense wavelength-division multiplexing (DWDM) networks. These new technologies are certainly beneficial, but they also bring about new test and measurement challenges, in particular for optical spectrum analyzers (OSAs), versatile test instruments that are key to successful DWDM system commissioning and troubleshooting. Indeed, recent 40G/100G coherent systems featuring polarization multiplexing have made some traditional OSA measurements, such as optical signal-to-noise ratio (OSNR), impossible to carry out. This white paper first establishes why an OSA is a fundamental test instrument in DWDM networks. Next, it identifies common OSA measurements being performed in the field, and then explains why a Pol-Mux OSA is required to perform OSNR measurements of 40G/100G coherent networks. Lastly, it presents EXFO’s Pol-Mux OSA, the first third-party test instrument on the market that allows accurate OSNR measurement of Pol-Mux systems.
