DIN EN 62148-15:2010-09

This part of IEC 62148 covers the physical dimension and interface specifications for the discrete vertical surface emitting lasers (VCSEL) devices in optical telecommunication and optical data transmission applications. With increasing data rates in photonic networks on the basis of multimode fibres, these components gain more and more in importance. Without these components the jump from Gibabit/s-Ethanet to 10- or 100-Gigabit-Ethernet is inconceivable. The purpose of this part of IEC 62148 is to adequately specify the physical requirements of VCSEL devices that will enable mechanical interchangeability of laser devices or transmitter complying with this standard both at the printed circuit wiring board and for any panel-mounting equipment. The styles with LC, SC and pigtail connections are described. The standard provides manufacturers, users and developers security regarding the specification of the dimensions and the pin assignment. There is a reference to the standards for the mentioned connectors (IEC 61754-x), optical fibres (60793-2, all parts) and IEC 62148-1 (packaging and interface). The responsible Committee is Subcommittee UK 412.2 "Komponenten für Kommunikationskabelanlagen" ("Components for communication cabling systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
