The 100BASE SFP transceiver modules provide reliable Fast Ethernet (100 Mb/s) connectivity over fiber optic or copper media.
Conforming to the SFP MSA (SFF‑8074/8472) and IEEE 802.3u Fast Ethernet standards, these hot‑swappable modules are ideal for legacy industrial and enterprise applications that still require 100 Mb/s operation with modern SFP‑based switches and media converters.
Available in 100BASE-FX, 100BASE-LX, 100BASE-BX (BiDi), and 100BASE-T (copper RJ45) variants, they offer cost‑effective solutions for point‑to‑point links up to 120 km over single‑mode fiber.

FAQ – 100BASE SFP Transceiver Modules
1. What is a 100BASE SFP transceiver?
A 100BASE SFP is a Hot‑Pluggable module supporting Fast Ethernet (100 Mb/s) over fiber or copper, following IEEE 802.3u and SFP MSA standards.
2. Which types of 100BASE SFP modules are available?
Common types include 100BASE‑FX (1310 nm MMF 2 km), 100BASE‑LX (1310 nm SMF 20 km), 100BASE‑BX (BiDi up to 40–60 km), and 100BASE‑T (RJ45 Copper 100 m).
3. Can a 100BASE SFP be used in Gigabit or 10G SFP+ ports?
Generally no—most SFP+ and 1G ports require a minimum of 1 Gbps; use 1000BASE SFP modules instead. Some dual‑speed ports support 100 Mb/s if specified by the device vendor.
4. What is the maximum distance supported by 100BASE SFP?
Typical reach ranges from 2 km (100BASE‑FX) to 20 km (LX) and up to 120 km (for long‑haul 1550 nm modules).
5. Do 100BASE SFP modules support DDM/DOM monitoring?
Some versions include Digital Diagnostics (DDM) per SFF‑8472 for temperature, voltage, and optical power readouts.
6. Are 100BASE SFP modules compatible across different brands?
Yes, MEFiber 100BASE SFPs are fully MSA‑compliant and work with industry‑standard switches from Cisco, HP, Huawei, Juniper, and others.
7. What temperature ranges are available for industrial use?
Commercial (0 – 70 °C) and industrial (‑40 – 85 °C) temperature grades are available for harsh environments.
8. Where are 100BASE SFP modules most commonly used?
They are common in industrial Ethernet, CCTV video links, and legacy Fast Ethernet networks needing reliable fiber extensions.
