1.4. Product Descri ption

LC-UPC BOAs are singlem ode, fiber optic, passi ve devices for reduc ing the ampli tude of a signal

without appr ec iably di stor ti ng the waveform. These attenuators are used for power equal ization at the

patch panel or at the rec eiver and also for attenuat ing t he si gnal power level t o br ing it in l ine with the

dynami c r ange of the receiver.

4. QUALIFICATION TEST MET HODS

4.1. Initial Optical Performanc e - New Product

A. Attenuation Toleranc e

Al l singlemode attenuation was measured in ac c or danc e with IEC 61300- 3- 4 or FOTP - 171,

Method D3, processes. The init ial optical power through t he test leads was measured. T he

att enuator speci men was inserted between the t est leads and optical power was measured. The

att enuati on was calculated by taking the differenc e between the initial and the final

measurements.

The measured attenuation was compared to the fixed attenuator value. The differenc e must meet

the permissible tol er anc e for that attenuator value. A ttenuation was measured at 1310 and 1550

nm.

Aft er eac h sequential test, opti c al power readings were perm it ted to be compensated by c hanges

in a source monitor c able. In cases wher e a c ontrol c able was also used and exceeded limit s

stated in the specifi c ati on, the change in t he c ontrol c able was also all owed to be fac tored i nto the

C. Pol ar ization Dependent Loss (P DL)

Using an optical source and PDL met er , the P DL loss of an attenuat or was measured between

4.2. Change in A ttenuation

The ini tial opt ical power (dBm) t hr ough the specimens was recorded befor e the test usi ng an optic al

source and detector. Relative opti c al power (dB) through the fiber was measured after eac h test.

Change in attenuation was calculat ed by taking the differenc e between t he initial measurement and

the final /aft er measurements. Optical power r eadings were c ompensated by c hanges i n the source

m onit or c able.

In cases where a control cabl e was also used and exceeded li mits stated in t he specifi c ation, the

4.8. Vibration

Specimens were subjected to si nusoi dal vibration, having a simple harmoni c motion with amplit ude of

1.52 mm [0.060 i n] doubl e ampli tude. T he vibr ati on fr equenc y was varied uniformly between the limits

of 10 and 55 Hz and back to 10 Hz in approx imately 4 m inutes for one cycl e. Ex posure tim e was 2

and 6 feet heights per GR-326-CORE, and cycl ed at a rate not in ex cess of 300 cycles per hour.

Opt ical perfor manc e was measured at ambient c onditions before and aft er test.

C with pH of 5.5 ± 0. 5.

Opt ical perfor manc e was recorded at ambient befor e and after test.

5.4. Thermal Shock

Specimens were subject ed to 20 cycles between 0 and 100

C. Each cycle contained a 30 m inute dwell

at each temperatur e extreme with transfer time l ess than 2 mi nutes. Opt ical perfor mance was

recorded at ambient before and after t he exposure.

5.5. Temperature Cycling

Specimens were subject ed to 500 cycles between -40 and 75

C. O pti c al perfor manc e was recorded at

am bient befor e exposure and at the compl eti on of testi ng.

5.6. Temperature-humidi ty Cycling

Specimens were subject ed to 5 cycles between -40 and 75

C with 90% relat ive humidi ty at 75

C. Each

cycle consi sted of a 5 hour dwell at each t emperat ure ext reme. Optical performance was recorded at

am bient befor e and after test.

5.7. Low Temper ature Storage

Specimens were subjected to 2500 hour s at - 40

C. Spec imens were removed from the c hamber and

optical performanc e measured at 0, 168, 500, 1000 and 2500 hours.

5.8. High Temperatur e S torage (Damp Heat)

Specimens were subjected to 2000 hour s at 85

C with 85% relat ive humidi ty. S pec imens were

removed from the chamber and optic al perfor manc e measured at 0, 100, 168, 500, 1000 and 2000

hours.

5.9. High Temperatur e A ging (Dr y Heat)

Specimens were subjected to 5000 hour s at 85

C with relat ive humidi ty less than 40%. Specimens

were removed from the c hamber and opti c al perfor mance measured at 0, 168, 500, 1000, 2000 and

5000 hours.
