SFP Transceiver

An SFP (Small Form-factor Pluggable) optical transceiver is a compact, hot-swappable module that connects a network switch, router, or network interface card to a fiber optic or copper cable. It converts electrical signals into optical signals for transmission and back again at the receiving end. Because of its standardized form factor, an SFP optical transceiver can be swapped without powering down the device, making it a flexible building block for modern fiber optic networks.

sfp, sfp+, and higher-speed variants share the same physical form factor but operate at different data rates.

- standard sfp supports up to 1 gbps, making it suitable for gigabit ethernet links.

- sfp+ (10g sfp transceiver)supports up to 10 gbps for higher-throughput applications.

- high-speed transceivers go further still — sfp28 supports up to 25 gbps, qsfp+ up to 40 gbps, and qsfp28 up to 100 gbps — covering data center spine-leaf architectures and high-performance computing requirements. 

l Multimode SFP fiber optic transceivers use 850 nm or 1300 nm wavelengths over 50/125µm or 62.5/125µm fiber, supporting distances up to 550 meters — suited for intra-building or campus links.

l Single-mode SFP optical transceivers use 1310 nm or 1550 nm wavelengths over 9/125µm fiber, supporting distances from 2 km up to 80 km or beyond — the standard choice for inter-building and long-haul deployments. 

Most switches follow the SFP Multi-Source Agreement (MSA) standard, which defines a common electrical and mechanical interface. Wintop's SFP Optical transceivers are MSA-compliant and designed for broad cross-brand compatibility. That said, some vendors implement proprietary encoding checks. Contact our team with your switch model to confirm compatibility before ordering.

Commercial-grade optical transceiver modules typically operate from 0°C to +70°C and are suited for data centers and office environments. Industrial-grade modules extend this range to -40°C to +85°C and are designed for outdoor enclosures, factory floors, utility substations, and other harsh environments. Confirm the operating temperature specification in each product datasheet before deployment in extreme conditions.
