This part of IEC 62148 covers the design guide of the electrical interface for photonic integrated circuit (PIC) packages using silicon fine-pitch ball grid array (S-FBGA) and silicon fine-pitch land grid array (S-FLGA). In this document, the electrical interface for the S-FBGA package is informative.

The purpose of this document is to specify adequately the electrical interface of PIC packages composed of optical transmitters and receivers that enable mechanical and electrical interchangeability of PIC packages

The electrical continuity test is to verify that cable metallic elements are electrically continuous throughout the cable.  Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a “goodness of manufacture" criteria.  Typically, the test is one of continuity and carries no resistance or conductivity requirement.  The metallic elements may be tested individually or may be tested as a total group.  Since this latter criterion is frequently the case, all elements are to be measured as a group unless specified otherwise.

NOTE Detail specifications may allow such elements as strength members to be non-continuous throughout the cable. This is a special case, and attention is directed to the detail specification.

The short-circuit test is intended to assess the performance of the OPGW (optical ground wire) or OPPC (optical phase conductor) under typical short-circuit, or the impact on the performance of OPAC (optical attached cable) under short-circuit current on the messenger wire.

This part of IEC 60794 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, as well as hybrid telecommunication cables having a combination of both optical fibres and electrical conductors.

The object of this standard is to define test procedures to be used in establishing uniform requirements for the material compatibility performance of cables, cable components, and cable subassemblies.

Compatibility of materials within a cable has the potential to involve a range of material pairs.  However, experience has shown that the most pertinent evaluations are of the cable filling and flooding materials interactions with other materials in the cable.

Throughout the standard the wording “optical cable” may also include optical fibre units, microduct fibre units, etc.

See IEC 60794-1-2 for general requirements and definitions and reference guide to test methods of all types.

This part of IEC 61300-3 describes methods available to measure the wavelength dependence of attenuation and return loss of two port, single mode passive optical components. It is not, however, applicable to dense wavelength division multiplexing (DWDM) devices. Measurement methods of wavelength dependence of attenuation of DWDM devices are described in IEC 61300-3-29.

There are two measurement cases described in this standard:

Measurement of attenuation only;

Measurement of attenuation and return loss at the same time.
