An SFP (Small Form-factor Pluggable) is a compact, hot-pluggable transceiver module that allows networking equipment — including switches, routers, servers, and media converters — to support different physical media, such as optical fiber or copper, without replacing the host. An SFP (Small Form-factor Pluggable) is a compact, hot-pluggable transceiver module that allows networking equipment — including switches, routers, servers, and media converters — to support different physical media, such as optical fiber or copper, without replacing the host. Discover fiber to ethernet converters for extending your network. Find gigabit media converters with reliable performance on Amazon. Support line rates up to 400 Gbps over a single-fiber bidirectional transmission. Get optical amplifier/multiplexer functionality in a pluggable form factor deployed in routers. Extend 100 GbE coherent links from QSFP28 ports reaching up to 80 km over dark fiber and up to 300 km over amplified DWDM. 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. This modular. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. An optical module usually consists of an optical transmitting device (TOSA, including a laser), an optical receiving device (ROSA, including a photodetector).
