SFP optical modules consist of the following core components: optical transceiver assembly, PCB board, optical interface, metal housing, dust plug and metal pull tab. TOSA (Transmitter Optical Sub-Assembly): Converts input electrical signals into optical signals. Choosing the wrong SFP optical module can result in link failure, instability. SFP (Small Form-factor Pluggable) is a compact, hot-pluggable network interface module used to connect network devices (switches, routers, firewalls) to fiber optic or copper cables. The Cisco ® 10GBASE SFP+ modules (Figure 1) give you a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider.
