General Information

Overview
EN 62148-2:2011/A1:2025 is a CLC/CENELEC adoption of IEC 62148-2:2010 with Amendment 1 (IEC 62148-2:2010/AMD1:2024). It specifies package and interface conventions for SFF 10-pin optical transceivers - compact, pluggable fibre optic active components used in telecom and data communications equipment. This amendment updates the original European Standard without modification and introduces changes such as a revised electrical terminal numbering assignment.
Key topics and requirements
- Scope: Package and interface standards for SFF (small form factor) 10-pin transceivers - mechanical, electrical and optical interface conventions (as defined in the base standard and this amendment).
- Electrical terminal numbering: Amendment A1 replaces the original Figure 1 with a new electrical terminal numbering assignment (viewed from above with pins underneath). The figure identifies key items: HL (housing leads), MS (mounting studs), Rx (receiver section), Tx (transmitter section).
- Package/interface elements: Standard covers pin assignments and interface points relevant to mounting, housing leads and the Tx/Rx sections - supporting consistent mechanical and electrical interoperability across manufacturers.
- Normative references & IP considerations: The amendment follows IEC development procedures and draws attention to referenced documents and potential patent rights; implementers should check referenced standards and IEC patent database.
Practical applications
- Ensures mechanical and electrical interoperability of SFF 10-pin transceivers across vendors.
- Used by module manufacturers to design compliant transceiver housings and pinouts.
- Supports system integrators and OEMs specifying module interfaces for switches, routers and optical line cards.
- Guides test laboratories and conformity assessors in verifying mechanical and electrical interface compliance.
- Useful for procurement and standards teams creating product specifications and ensuring cross-vendor compatibility in data centers and telecom networks.
Who uses this standard
- Optical transceiver designers and manufacturers
- Network equipment vendors (switches, routers, line cards)
- Test labs and conformity assessment bodies
- Standards committees and procurement engineers
- System integrators working with pluggable optical modules
Related standards
- IEC 62148 series (package and interface standards for fibre optic active components) - EN 62148-2 aligns with IEC 62148-2:2010/AMD1:2024.
- Users should consult other parts of IEC 62148 and referenced IEC/CENELEC documents for full mechanical, electrical and optical requirements.
