IEC 62148-7 pdf download Fibre optic active components and devices – Package and interface standards – Part 7: SFF LC 10-pin transceivers
This part of lEC 62148 covers the physical interface specifications for the SFF LC 10-pin fibreoptic transceiver module family.
The intent of this standard is to adequately specify the physical requirements of an opticaltransceiver that will enable mechanical interchangeability of transceivers complying with thisstandard both at the printed circuit wiring board and for any panel-mounting requirement.
The following referenced documents are indispensable for the application of this document.For dated references,only the edition cited applies.For undated references, the latest editionof the referenced document (including any amendments) applies.

3 Definition and abbreviation
For the purpose of this International Standard, the following abbreviation and definition apply.3.1 Definition
small form factor optical transceiver
a compact optical digital signal transceiver whose package has the same cross sectionaloutline as the receptacle of RJ-45 electrical connector
SFF: small form factor
The transceiver described in this document is classified as type 1 according to the definitionsof IEC 62148-1.
5 Specification of optical connector interface modules
This standard applies to the LC optical connector interface.Detailed dimensions of the opticalreceptacle are provided in Clause 7.
The assignment of the optical transmit and receive ports is aligned to the electrical pins.Onehalf of the module corresponds to the ‘transmit’ side and the other to the ‘receive’side.Assignments are shown in Figure 1 (viewed from the top of the module with pins underneath).
6 Electrical interface
The electrical interface in this standard defines only the basic functionality of each pin.
6.2 Numbering of electrical terminals
Pin-numbering assignments are shown in Figure 1 (viewed from the top of the module withpins underneath).
