SFP transceiver Lenovo 46C3449 850nm multimode 550m

The Lenovo 46C3449 SFP transceiver operates at 850 nm and is designed for multimode fiber links with a reach of up to 550 meters. This hot-pluggable module fits standard SFP ports and provides a compact, low-profile form factor suitable for short-range optical connections in data centers, server rooms and campus networks. The transceiver is intended for straightforward port upgrades or replacement of existing SFP modules while maintaining compatibility with devices that accept standard SFP form-factor optics.

Advantages

The module offers a compact, industry-standard SFP form factor that enables flexible port upgrades without requiring device downtime for replacement. Operating at 850 nm for multimode fiber, it supports short-range links up to 550 meters, making it suitable for inter-rack and intra-building connections. Its hot-pluggable design simplifies deployment and maintenance, and the optical characteristics are optimized for short wavelength multimode fiber environments.

Suitable for

• Short-range multimode fiber links in data centers and server rooms
• Inter-rack and intra-building connections up to 550 meters
• Port upgrades and spare module replacement in compatible network switches
• Campus network links between buildings using multimode fiber

Key specifications

• Optical wavelength: 850 nm
• Fiber type: Multimode (MMF)
• Maximum link length: up to 550 meters (multimode)
• Form factor: Small Form-factor Pluggable (SFP)
• Interface: Duplex optical LC connector
• Hot-pluggable design for live replacement

How to use

Insert the SFP transceiver into a compatible SFP slot on the network switch or device until it clicks into place. Connect appropriate duplex multimode fiber patch cables with LC connectors to the module's optical ports, ensuring correct transmit/receive orientation. Configure the host device port according to the network and interface settings required by your environment. For removal, power down the port if recommended by the device manufacturer or follow hot-swap procedures, then depress the module latch and pull the transceiver straight out.

Usage recommendations

Use multimode fiber cables with suitable modal bandwidth for short-range links and maintain clean connectors to ensure optimal optical performance. Verify device compatibility with SFP optics and confirm supported link distances for the specific multimode fiber grade deployed. Store unused modules in protective packaging to prevent contamination or damage to the optical interface.
