Optical Transceivers of Small Form (SFF) For Advanced Applications (High transmission rate, single mode)

Abstract

Small Form-Factor Pluggable (SFP) is a compact, hot-swappable network interface module format used in telecom and datacom applications. SFP interfaces on network hardware are modular slots for specific media transceivers, such as B. Suitable for fiber optic or copper cables. The advantage of using SFPs over fixed interfaces such as the modular connectors in Ethernet switches is that individual ports can be equipped with different types of transceivers. SFF optical modules require new packaging technology because the optical axis of the optical part is much smaller than traditional optical modules, such as the "1by9" type, two types of optical packages are described, both for transceivers with MT-based sockets for single-mode applications. Optical coupling between optical components and fibers on the V-groove is achieved through passive alignment, reducing assembly time.
