No-Compromise Versatility for Metro and Long-Haul Testing

Today’s fiber networks integrate long-haul, CWDM and metro applications, making OTDR versatility a must. While long-haul architectures require high dynamic range values to reach greater distances, metro links demand an OTDR offering good resolution (short dead zones) due to the proximity of many connection points. Up to now, OTDR users had to compromise on one or the other and buy two units—a choice that they no longer have to make.

The FTB-7400E OTDR combines EXFO’s renowned optical performance and unparalleled software analysis with both short dead zones and high dynamic range values, delivering the versatility needed to test long-haul, CWDM and metro links with a single OTDR.

In addition, the FTB-7400E lets you test CWDM networks with wavelength configurations that comply with the ITU G.694.2 CWDM grid. With high dynamic range and short dead zones, the FTB-7400E measures end-to-end loss through multiplexers and demultiplexers, helping service providers speed up troubleshooting and maintain first-class quality of service (QoS) standards.

Pulse Selection vs. Dead Zone

Application Notes

Generally speaking, the rationale behind selecting the shortest pulse on an OTDR is to obtain the best spatial resolution, and the best event and attenuation dead zones needed to detect and measure very closely spaced events.

OTDRs are often used with a launch fiber/cable, and may also use a receive fiber/cable. The launch cable, aka “pulse suppressor” or “dummy fiber,” allows the OTDR to recover after the test pulse is sent into the fiber. This cable provides an invaluable reference on the first connector of the cable under test for determining its loss and reflectance.

A heterogeneous network (HetNet) combines distributed antenna system (DAS) solutions, small-cell technologies and WiFi infrastructure to enable wireless broadband coverage and capacity. All these technologies are supported by a fiber-optic network – a HetNet is where the wireline meets the wireless.

In this quickly evolving industry, determining which technology is best suited to deliver bandwidth and an awesome user experience in a specific environment can be confusing.
