BRT-320A

NETWORK TESTING—OPTICAL

OPTICAL RETURN LOSS TEST SET

Telecom Test and Measurement

www.EXFO.com

Features Sous-titre

Built-in thermoelectrically cooled (TEC) laser(s)

Range of 0 dB to –70 dB

Quick and easy to operate

Rugged, field-ready

Stores up to 300 readings

Fast Stabilization

EXFO’s BRT-320A is a field-ready return loss test set offered in five configurations:

1310 nm, 1550 nm or 1625 nm; dual-wavelength 1310/1550 nm or 1550/1625 nm.

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. Other features include three-way powering

(rechargeable NiCd battery pack, 9 V battery, AC adapter/charger), 0.01 dB

resolution, ± 0.1 dB linearity, internal InGaAs detector, low-battery indicator and a

protective holster with shoulder strap.

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. These environments often

require complete network ORL characterization and component reflectance

verification. The BRT-320A also functions as a stable, continuous-wavelength light

source for attenuation measurements. Other applications include fiber component

and cable manufacturing.
