5.1 THE PROCESS FOR EVALUATION AND APPROVAL OF MQJs DEVELOPED IN ACCORDANCE

WITH NAVSEA DRAWING 6877804 IS DESCRIBED HEREIN.

5.2 PREFERRED PROCESS

5.2.1 ORGANIZATIONS SEEKING APPROVAL FOR THEIR MQJs MUST CONTACT, IN WRITING, NSWCDD, AT DLGR_NSWC_FO_ENG@NAVY.MIL REQUESTING THE APPROVAL OF THEIR

MQJs. NSWCDD WILL CONTACT THE ORGANIZATION SEEKING APPROVAL AND PROVIDE

GUIDANCE ON HOW TO PROCEED THROUGH THE PROCESS.

5.2.2 ORGANIZATION SEEKING APPROVAL PROVIDES MQJ CANDIDATES (SEE 5.3 FOR

REQUIRED SUBMISSIONS) OR AS DIRECTED BY NSWCDD.

5.2.3 NSWCDD VERIFIES THAT THE PRODUCTS PASS THE REQUIREMENTS HEREIN (SEE SECTION

2 AND APPENDIX A).

5.2.4 UPON SUCCESSFULLY COMPLETING THE PROCESS, NSWCDD WILL CONTACT THE

ORGANIZATION SEEKING APPROVAL AND NOTIFY THEM OF THE RESULTS VIA EMAIL. THE

PARTS THAT HAVE OBTAINED FULL APPROVAL (SEE TABLE V OR TABLE VI) WILL BE ADDED

TO THE RECOMMENDED TEST EQUIPMENT LIST WHICH IS PUBLISHED ON THE NSWCDD

FIBER OPTIC WEBSITE.

5.2.5 INTERIM APPROVED MQJs (SEE TABLE V OR TABLE VI) WILL NOT APPEAR ON THE

RECOMMENDED TEST EQUIPMENT LIST. TO OBTAIN FULL APPROVAL FOR AN INTERIM

APPROVED MQJ THE ORGANIZATION SHALL, UPON FIRST SALE OF AN INTERIM APPROVED

MQJ, SEND A COPY OF THE FOLLOWING DATA FOR THE MQJ TO THE APPROVING ACTIVITY:

INSERTION LOSS, RETURN LOSS (IF SINGLE MODE), INTERFEROMETER MEASUREMENTS,

AND THE CUSTOMER’S POC INFORMATION. IF THE DATA INDICATES PASSING RESULTS

AND THE CUSTOMER IS SATISFIED WITH THE PRODUCT, THE ORGANIZATION WILL THEN

RECEIVE FULL APPROVAL FOR THAT PRODUCT AND THE PRODUCT WILL BE ADDED TO THE

RECOMMENDED TEST EQUIPMENT LIST.

EVALUATION OF MEASUREMENT QUALITY JUMPERS

A.1 VISUAL INSPECTION AND ENDFACE GEOMETRY

a. TAKE SEVERAL PICTURES OF THE MQJs UNDER TEST AT DIFFERENT ANGLES.

b. COMPARE MQJs UNDER TEST WITH NAVSEA DRAWING 6877804 AND NOTE ANY

DIFFERENCES.

c. INSPECT PHYSICAL CONSTRUCTION OF MQJs FOR QUALITY OF WORKMANSHIP AND

COMMENT.

d. VISUALLY INSPECT ALL LIGHT DUTY CONNECTORS, TERMINI PINS AND SOCKETS ON

MQJs AND COMMENT ON WORKMANSHIP. THE FIBER OPTIC SECTION USES A 400X

VIDEO SCOPE WITH A BLUE LIGHT TO VIEW CONNECTOR AND TERMINI END FACES. IN

ORDER TO PASS THE INSPECTION, THERE SHALL BE NO VISIBLE SCRATCHES

OBSERVED WHEN USING THE VIDEO SCOPE.

e. CHECK ALL LIGHT DUTY CONNECTOR ENDFACES OF MQJs USING THE

INTERFEROMETER AND PRINT COPIES OF THE MEASUREMENTS. THE REQUESTING

ORGANIZATION SHALL SUPPLY COPIES OF THE INTERFEROMETER MEASUREMENTS

OF ALL SAMPLES SUBMITTED. CONNECTORS SHALL MEET GR-326 CRITERIA FOR

DOMED PHYSICAL CONTACT CONNECTORS. THE FOLLOWING IS THE CRITERIA:

i. RADIUS OF CURVATURE (ROC) SHALL BE BETWEEN 7MM AND 25 MM

ii. APEX OFFSET OF THE SPHERICAL ENDFACE TO THE AXIS OF THE FERRULE SHALL

BE LESS THAN 50 MICROMETERS

iii. FIBER PROTRUSION SHALL NOT EXCEED 50 NM; WHEN ROC IS 25 MM, FIBER

UNDERCUT SHALL BE NO MORE THAN 50 NM. FOR ALL OTHER ROC VALUES THE

MAXIMUM UNDERCUT IS GIVEN IN TABLE A-I.

A.2 OPTICAL INSERTION LOSS MEASUREMENTS

NOTE: FOR SINGLE MODE FIBER MEASUREMENTS, THE REFERENCE CABLE MAY INCLUDE A

SINGLE LOOP WITH A DIAMETER OF 30 MILLIMETERS (1 INCH) TO ELIMINATE HIGHER

ORDER MODE POWER.

NOTE: THE TIME DELAY BETWEEN THE MEASUREMENT OF P1 AND P2 SHALL BE KEPT TO A

MINIMUM TO PREVENT INACCURATE READINGS.

NOTE: THE REFERENCE CABLE TO LIGHT SOURCE CONNECTION SHALL NOT BE DISTURBED

BETWEEN THE MEASUREMENT OF P1 AND P2 TO PREVENT INACCURATE READINGS.

NOTE: A WIPE DAMPENED WITH ALCOHOL MAY BE USED TO CLEAN THE ADAPTERS AND

CONNECTORS AND THEY MAY BE BLOWN DRY WITH AIR BEFORE MAKING EACH

CONNECTION.

NOTE: THIS PROCEDURE INVOLVES THE USE OF REFERENCE MQJs. DEFECTIVE OR DIRTY

MQJs WILL LEAD TO UNACCEPTABLE LOSS VALUES. THE REFERENCE MQJ SHOULD BE

CLEAN AND OF KNOWN QUALITY.
