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.
