Product Features
Technical Overview
This media converter operates at Fast Ethernet speeds with support for both 10/100Base-TX over twisted pair and 100Base-X over multimode fiber. The ST fiber port uses 1300 nm wavelength optical signaling with duplex ST connectors, supporting transmission distances up to 2 kilometers (1.24 miles) over multimode fiber cable.
The device maintains signal integrity across media conversions while providing electrical isolation between copper and fiber segments. This isolation helps protect sensitive network equipment from ground loops, voltage spikes, and electromagnetic interference that can occur in industrial or extended-distance deployments.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

Deployment / Use Cases
This media converter excels in scenarios requiring network extension between buildings, across industrial facilities, or through environments with electromagnetic interference. The fiber optic connectivity provides electrical isolation while extending network reach beyond copper limitations.
Common deployment scenarios include connecting network segments between separate buildings on a campus, extending networks across manufacturing floors with heavy machinery, linking surveillance systems across large properties, and bridging network gaps in outdoor or temperature-controlled environments. The rack-mountable option allows for clean integration in network closets or equipment racks alongside other networking hardware.
Building-to-Building Connectivity
Connect network segments between separate structures using fiber optic cabling for distance and electrical isolation.
Industrial Network Extension
Extend networks across factory floors or outdoor areas where temperature fluctuations and environmental factors require hardened equipment.
Physical Profile
The compact external design measures 3.50" (88.90 mm) in height, 3" (76.20 mm) in width, and 1" (25.40 mm) in depth, with a lightweight 4.80 oz (136.08 g) construction. The form factor supports both external placement and rack-mountable installation, providing flexibility for various deployment scenarios. The small footprint makes it suitable for space-constrained environments while the rack-mount capability allows for organized installation in standard equipment racks.

FAQ
What types of network media does this converter support?
The LBH100AE-H-ST supports both twisted pair copper Ethernet (10/100Base-TX) and multimode optical fiber (100Base-X). It converts signals between these two media types, allowing network extension from copper to fiber or vice versa while maintaining Fast Ethernet speeds up to 100 Mbps.
What is the maximum distance supported over fiber?
This media converter supports transmission distances up to 2 kilometers (1.24 miles) when using multimode fiber optic cable. This extended reach far exceeds the 100-meter limitation of standard copper Ethernet, making it ideal for connecting network segments across buildings or large facilities.
What does 'hardened' mean for this media converter?
Hardened indicates the device is designed to operate reliably across temperature variations and in challenging environmental conditions. Unlike standard media converters that might fail in extreme temperatures or harsh industrial settings, this hardened model maintains stable performance where temperature fluctuations or physical stress are concerns.
How many ports does this converter have and what types?
The converter features three total ports: two RJ45 copper ports for 10/100Base-TX twisted pair Ethernet connections and one ST duplex port for multimode fiber optic connections. This configuration allows flexible connectivity between copper and fiber network segments with options for multiple copper devices or pass-through connections.
What power requirements does this media converter have?
The converter uses an external power supply that accepts 100-240 VAC input, providing global compatibility with various electrical standards. The external power design simplifies installation without requiring internal power connections, and the wide voltage range ensures reliable operation in different geographic locations.
Is this device rack-mountable?
Yes, the LBH100AE-H-ST supports both external placement and rack-mountable installation. The compact form factor allows for flexible deployment either as a standalone unit or mounted in standard equipment racks, providing installation options that suit various network closet and facility layouts.
