Network Media Converter Cisco Gigabit Ethernet LH Mini-GBIC SFP Transceiver MGBLH1-EU

This Cisco Network Media Converter Gigabit Ethernet LH Mini-GBIC SFP Transceiver (MGBLH1-EU) is an easy-to-install module that adds Gigabit fiber connectivity to compatible switches and media converters. The module uses a 1310 nm wavelength and supports multimode and single-mode fiber links, enabling link distances from hundreds of meters up to 40 kilometers depending on the fiber type used.

Advantages

The SFP form factor provides a compact, hot-pluggable solution for upgrading switch ports to Gigabit fiber. With 1310 nm operation the module is compatible with both multimode and single-mode fibers and can achieve long-range links up to 40 km on single-mode fiber. It is interoperable with devices that accept standard mini-GBIC/SFP transceivers and is straightforward to install without special tools.

Suitable for

• Connecting two switches at short to long distances over fiber
• Extending network segments between buildings or floors
• Replacing or adding SFP ports in compatible Cisco equipment and other SFP-supporting switches

Key specifications

• Manufacturer: Cisco
• Model / MPN: MGBLH1-EU
• Form factor: Mini-GBIC (SFP)
• Wavelength: 1310 nm
• Supported fiber types and ranges: 62.5/125 µm MMF up to 500 m; 50/125 µm MMF up to 2,000 m; 9/125 µm SMF up to 40 km

How to use

Power off or follow the hot-swap procedure of your switch or media converter if supported. Insert the Mini-GBIC (SFP) transceiver into an available SFP slot until it clicks into place. Connect the appropriate fiber patch cable (matching core size and connector type) and secure any dust caps. Configure the switch port as required (speed/duplex and VLAN settings) and verify link status on the device.

Recommendations

Use fiber patch cables and connectors that match the module’s fiber type (multimode or single-mode) and follow distance guidelines: 62.5/125 µm MMF up to 500 m, 50/125 µm MMF up to 2,000 m, and 9/125 µm SMF up to 40 km. Observe electrostatic discharge (ESD) precautions when handling the transceiver and keep optical ports covered when not connected.
