21、to specify electrical input/output parameters for fiber optic.termina1 devices and establish uniform requirements with respect to classification by device type and function; electrical and optical measurement methods; environmental and mechanical tests; categories of assessed quality; and safety, wh

27、Units, graphic symbols and letter symbols shall, whenever possible, be taken from the following Publications: ANSI C42.100 ANSI Y32.16 ANSI Y10.19 IEC 27 IEC 117 IEC 148 (NOTE: The U.S. documents and the International documentation must be cross-referenced prior to the issuance of this Generic Speci
28、fication.) RS-509 Page 3 2 . 3 Terminology Terminology shall, whenever possible, be taken from the following publication: RS-440, “Fiber Optic Connector Terminology.“ Fiber Optic Terminal Device - A device including active element(s) intended for fiber optic telecommunications use, which converts an
29、 electrical signal into an optical signal, and vice-versa. It shall have integral fiber optic connector( s) or fiber optic pigtail connection( s) , in addition to specified accessible electrical input or output connections. NOTE 1: NOTE 2: NOTE 3: This encompassess a wide range of terminal devices;
30、however, in each case, the device shall have an integral fiber optic connector(s) or fiber optic pigtail( s) . Device examples include: (i) Discrete source or detector elements of a fiber optic system; (2) Fiber optic assemblies or modules consisting of various discrete component s/ el emen t s or i
31、ntegrated circuit techniques, or conventional printed circuit board construction; (3) Fully integrated versions of “(2)“. semiconductor devices, used as separate Additional functional classifications include: Transmitters (Tx), Receivers (Rx), and Repeaters having either digital or analog signal tra
32、nsmission capability. Pigtail Connection - A short length of optical fiber (typically less than 2m in length) permanently attached to the active optoelectronic element (e.g., PIN photo diode, laser diode, etc.) of the terminal device, and intended to be spliced or connected to a compatible fiber of
33、a fiber optic cable. Effective Optical Parameters - Terminal device optical parameters (e.g. , Tx optical output power, Rx sensitivity vs. wavelength, etc.) are specified and measured at the free end of a Standard Test Fiber, and not at a directly accessible optical port. The fixed end of this Stand
34、ard Test Fiber shall be coupled to the terminal device by RS-509 Page 4 i Voltage Optical Power Time State (Radiant Flux) HIGH vm LOW 1 Input Output Input Output Input Output Input Output OH IIH OH +IH +OH tIH tOH I IL IIL IOL +IL *OL tIL toL - Standard Coupling Means and shall be used for specifica
35、tion purposes regardless of whether the terminal device optical interface incorporates an integral fiber optic connector or a fiber pigtail. (NOTE: This procedure provides a fixed reference method for specifying optical parameters, which are meaningful to overall fiber optic transmission system perf
36、ormance rather than the unique properties of the particular internal optoelectonic device.) Standard Test Fiber - A fiber with tightly controlled and specified steady state parameters (e.g., NA, core diameter, index profile, and concentricity) and specified length which is coupled to the terminal de
37、vice by Standard Coup1 ing Means . It provides a fixed optical port interface for the test and specification purposes. (NOTE: It is expected that several Standard Test Fibers will be specified over time; in the interim period, vendors should choose representative test fiber( s) and specify fiber par
38、ameters on data sheets.) Standard Coupling Means - A reference standard fiber optic connector or splice used to mechanically couple a Standard Test Fiber to the integral fiber optic connector or pig- tail of a terminating device in a precise manner for test purposes. 2.4 Letter Symbols The subscript
39、 sequence for voltage, current, optical power . and time (duration/period) shall be as outlined: 1st Subscript - Input/Output Identification 2nd Subscript - HIGH or LOW State 3rd Subscript - Further Qualification is Required EXAMPLES: RS-509 Page 5 The following subscript sequence should be used for

46、mance Inspection (QCI) . This schedule shall also specify the grouping, sampling and periodicity for lot-by-lot and periodic inspection. The inspection levels and AQLs shall be selected from those given in ANSI 21.4. If required, more than one (QCI) schedule may be specified. 3.2.1 Certified Test Re
