Product Overview

8100-Series OTDR EVO Modules; For T-BERD/MTS-6000A/-8000 Platforms.

The VIAVI Solutions 8100-Series OTDR EVO family transforms fiber testing. Connect the OTDR EVO family anywhere on the fiber to characterize single-mode and multimode fibers for commissioning, network upgrades, and troubleshooting with the added insurance of workflow optimization and accurate fiber-link fingerprinting.

Key Features:

Up to 50 dB dynamic range
Integrated CW light source and broadband power meter (single-mode wavelengths)
PON-optimized to test through a 1x128 splitter
Single connector port for 1310, 1550, and inservice 1650 nm wavelengths
FiberComplete™ version available for automated bidirectional OTDR, IL, and ORL measurements
Built-in encircled flux multimode source compliant with IEC 61280-1-4 and TIA-526- 14-B

Benefits:

Industry-leading dead zone performance for full element event characterization on fiber links 2 m apart
Includes an integrated power meter, light source, and OTDR in a one-port tool for added flexibility
Instantaneous, automatic traffic detection avoids risking live signal interference or optical transmitter damage during an OTDR test
Eliminates OTDR interpretation errors with Smart Link Mapper (SLM) without compromising on test time
Reduces event loss measurement uncertainty and improves measurement repeatability

Notes:

(1) Laser at 25°C and measured at 10 µs.

(2) The one-way difference between the extrapolated backscattering level at the start of the fiber and the RMS (SNR=1) noise level, after 3 minutes averaging using the largest pulse width.

(3) Measured at ±1.5 dB below the peak of an unsaturated reflective event using the shortest pulse width.

(4) Measured ±0.5 dB from the linear regression using an FC/UPC reflectance and the shortest pulse width.

(5) 1625 nm is not available on the 8138C-65 version.

(6) At calibrated wavelengths.

(7) At calibrated wavelengths; multimode source (850 nm) is compliant to the IEC 61280-1-4 standard related to the encircled flux.

(8) Subtract 3 dB when in modulation mode (270 Hz/330 Hz/1 kHz/2 Khz).

(9) Measured at 1.5 dB below the peak of an unsaturated 27 dB reflective event using the shortest pulse width.
