Transceptor de fibra ótica SFP LEVELONE SFP-3411 — 1250 Mbit/s, 1310 nm, interface SFP, 3,3 V

The LevelOne SFP-3411 is a single-mode SFP fiber optic transceiver designed for Gigabit Ethernet links. It supports bidirectional data transfer up to 1.25 Gbps over a single duplex fiber core, operates at a wavelength of 1310 nm using an FP laser diode, and fits standard SFP slots. The module is compatible with 9/125 μm fiber and can reach distances up to 40 km. It is housed in a metal casing (silver) and is RoHS compliant.

Advantages

The SFP-3411 offers IEEE 802.3z compliance and SFP MSA compatibility for broad interoperability with switches, routers and media converters. It provides a duplex LC connector, supports Digital Diagnostics Monitoring Interface (DDMI) for status monitoring, and is hot-swappable for maintenance without downtime. The transceiver operates from a 3.3 V supply and meets common EMI/laser and RoHS standards.

Suitable for

• Gigabit Ethernet uplinks between switches and routers
• Optical links in data centers and telecom rooms up to 40 km
• Media converters and SFP-equipped network equipment requiring 1310 nm single-mode optics

How to use

Insert the SFP-3411 into an empty SFP slot of a compatible switch, router or media converter while the host supports SFP modules. Connect the duplex LC single-mode fiber cable (9/125 μm) to the LC port, observing correct polarity for transmit and receive fibers. Ensure the host device is powered and configured for a 1 Gbps link; the module is hot-swappable so it can be inserted or removed without shutting down the host if the device supports hot-swap operations.

Recommendations

Use quality single-mode 9/125 μm fiber with proper connectors and observe cleanliness best practices for LC connectors. Verify compatibility with the host device firmware and check DDMI readings for optical power and temperature to ensure reliable link operation.
