Product Features
Technical Overview
This converter operates with a 1300 nm wavelength on multi-mode fiber, compatible with core/cladding specifications of 100/140 µm, 62.5/125 µm, and 50/125 µm. The optical interface uses one duplex ST port, providing a robust physical connection for fiber optic cabling. Total port count is two, accommodating both the fiber link and integrated conversion circuitry.
Power is supplied via an included AC power supply, ensuring stable operation without reliance on network power. The device supports a maximum link distance of 5 kilometers (3.11 miles), extending T1/E1 circuits beyond typical copper limitations while mitigating electromagnetic interference.
Key Product Advantages
This converter eliminates distance constraints and signal degradation associated with long copper runs by leveraging fiber optic technology. It provides a clear path to modernize legacy T1/E1 circuits without replacing entire network infrastructures.
Extended Reach
Supports links up to 5 km, far exceeding typical copper limitations for T1/E1 circuits.
- Reduces signal loss over distance
- Enables campus or metro-area connections
Installation Flexibility
Rack-mountable, external, or wall-mountable form factor adapts to various deployment environments.
- Fits standard 19-inch racks
- Saves space in crowded network closets
Compliance & Reliability
TAA compliant and backed by a 2-year limited warranty, ensuring suitability for government and enterprise procurement.
- Manufactured in the United States
- Meets Trade Agreements Act requirements
Deployment / Use Cases
Deploy this converter to extend T1/E1 circuits between buildings in a campus environment, connecting central offices to remote telecommunication cabinets, or integrating legacy T1/E1 equipment into fiber-based network backbones. It is ideal for service providers, financial institutions, or any organization maintaining T-carrier or E-carrier circuits.
Common scenarios include linking PBX systems across separate facilities, extending WAN circuits to branch offices over fiber, or transitioning from copper to fiber in data center interconnects. The converter's compatibility with common multi-mode fiber types simplifies integration into existing fiber plant.
Service Provider Edge
Connect customer-premise T1/E1 equipment to fiber optic access networks, maintaining circuit integrity over longer distances.
Enterprise Network Modernization
Upgrade aging copper backbones to fiber without replacing T1/E1 compatible routers, multiplexers, or channel banks.
Physical Profile
The converter measures 1" (25.40 mm) in height, 3" (76.20 mm) in width, and 4" (101.60 mm) in depth, with an approximate weight of 6.40 oz (181.44 g). Its compact, low-profile design allows for dense rack mounting or discreet wall installation. The external power supply keeps heat dissipation away from the main unit, enhancing reliability in enclosed spaces.

User Manual
FAQ
What network technologies does this converter support?
This converter supports T1 and E1 network technologies. T1 is a North American standard operating at 1.544 Mbps, while E1 is a European standard operating at 2.048 Mbps. It converts these copper-based signals to fiber optic, allowing extension over multi-mode fiber up to 5 kilometers.
What type of fiber optic cable is compatible?
The converter is compatible with multi-mode fiber optic cables with core/cladding specifications of 100/140 µm, 62.5/125 µm, or 50/125 µm. It uses a duplex ST connector type, which is common in many existing fiber installations for robust physical connectivity.
What is the maximum distance supported?
The maximum supported distance is 5 kilometers (approximately 3.11 miles) over multi-mode fiber. This extends T1/E1 circuits far beyond the typical limitations of copper cabling, reducing signal loss and electromagnetic interference over long runs.
How is this converter powered?
The converter is powered by an included AC power supply. This external power source ensures stable operation independent of network power, making it suitable for environments where Power over Ethernet or other inline power methods are not available or applicable.
What mounting options are available?
This converter offers multiple mounting options: it is rack-mountable for standard 19-inch racks, can be used as an external standalone unit, or wall-mountable for flexible placement. Its compact dimensions (1" H x 3" W x 4" D) allow for space-efficient installation in network closets or equipment rooms.
Is this product TAA compliant?
Yes, this converter is TAA (Trade Agreements Act) compliant and manufactured in the United States. This makes it suitable for procurement by U.S. federal government agencies and other organizations requiring TAA-compliant networking equipment, backed by a 2-year limited warranty.
