Fiber optic transceiver module Lancom SFP-SR-MPO40

The Lancom SFP-SR-MPO40 is a fiber optic transceiver module designed for high-speed short-range data links. It supports a maximum data transfer rate of 40000 Mbit/s and operates at a wavelength of 850 nm. The module uses a QSFP+ form-factor interface and is compatible with a range of Lancom switches that accept QSFP+ modules. Its chrome-coloured housing provides a compact, rack-friendly solution for dense networking environments requiring reliable multimode fiber connections.

Advantages

The transceiver delivers a 40 Gbit/s class connection over multimode fiber at 850 nm, enabling increased throughput for aggregation and spine links in data centers. The QSFP+ interface simplifies installation into compatible ports and supports hot-plug replacement for minimal downtime. The compact form factor and standardized electrical/optical characteristics facilitate interoperability with networking equipment designed for QSFP+ modules.

Suitable for

• Short-range 40 Gbit/s uplinks between switches in data centers
• High-bandwidth server-to-switch connections over multimode fiber
• Aggregation and spine-leaf topologies requiring QSFP+ ports

Key specifications

• Interface type: QSFP+
• Maximum data transfer rate: 40000 Mbit/s
• Operating wavelength: 850 nm
• Optical medium: multimode fiber (MPO/MTP)
• Form factor: QSFP+ transceiver module
• Housing colour: chrome

How to use

Insert the module into a compatible QSFP+ slot on a supported Lancom switch or other vendor equipment that accepts QSFP+ transceivers. Ensure the host port is powered down or follow the equipment vendor’s hot-swap procedures if available. Connect the multimode MPO/MTP fiber cable to the module’s optical interface, observing proper polarity and connector cleanliness. After installation, verify link status and negotiated speed in the switch management interface and monitor for errors on the port.

Recommendations

Use certified multimode MPO/MTP cables rated for 40 Gbit/s transmission and maintain connector cleanliness with appropriate cleaning tools. For reliable short-range performance, match the fiber type and link budget to the module’s 850 nm wavelength characteristics and follow the host device’s compatibility list when selecting transceivers.
