Product Description
Exfo BRT-320A Optical Return Loss Test Set
Rent me for $150 a month
Different wavelength options available please call. Price may vary with installed options
Optical return loss (ORL) along a fiber span can reduce fiber system performance and increase bit error rate by degrading transmitter stability. The Exfo BRT-320A is a rugged, hand-held dual-wavelength (1310 and 1550 nm) test set for measurement of reflected power in optical cabling. It is ideal for local and long-distance Telco, CATV, utility, broadband, and transmission equipment manufacturing applications. Other applications include fiber component and cable manufacturing. Features a large, backlit LCD, non-volatile memory for 300 stored readings, built-in NiCad batteries, 9V alkaline battery backup, and AC adapter/charger. The Exfo BRT-320A has a thermoelectrically cooled laser and low- drift photodetectors to ensure years of consistent measurements.
Back Reflection Test Set
- 1300/1550 nm dual wavelength lasers as an option
- Direct and isolated back reflection measurements
- Back reflection readings can be stored; up to 300 memories
Optical Specifications
- Source: Lasers
- Wavelength: 1300 ± 15 / 1550 ± 15 nm depending upon options
- Spectral Width: 5/5 nm
- Range: -8 to -70 dB
- Resolution: ±.05 dB
- Power Output: -6/-6 dBm
EXFO's BRT-320A is a field-ready return loss test
set offered in five configurations: 1310 nm, 1550 nm or 1625 nm
(single-wavelength), as well as 1310/1550 nm or 1550/1625 nm
(dual-wavelength). All come equipped with rapidly stabilizing TEC
lasers and low-drift photodetectors to ensure constant optical
return loss (ORL) measurements year after year.
Built-In User-Friendliness
Use the BRT-320A to read backreflection from 0 dB
to -70 dB and easily store up to 300 readings in a non-volatile
memory. ORL readings appear directly on the large, backlit LCD. An
ORL zero function accounts for incidental backreflections before
the point of measurement and complies with Bellcore optical
continuous wave reflectometer (OCWR) requirements. In User
Calibration mode, you can calibrate the unit to a known
reflection.
Reveal Return Loss Problems
Many digital and analog fiber systems require ORL
characterization. ORL along a fiber span is a combination of
Rayleigh scattering and Fresnel reflections. Together, these
phenomena can reduce fiber system performance and increase bit
error rate (BER) by degrading transmitter stability. The BRT-320A
measures cumulative link return loss and individual component
reflectance to reveal potential ORL problems before they seriously
affect your applications.
Versatile
The BRT-320A is ideal for local and long-distance Telco, CATV, utility, broadband and transmission equipment manufacturing applications.
