MTRJ-MTRJ Multimode OM1 Ultra Fiber Cable | High-Performance Connectivity
The iFiber Optix MTRJ-MTRJ Multimode OM1 Ultra Fiber Cable delivers seamless connectivity between compact MTRJ duplex interfaces on both ends — providing a direct, high-performance OM1 multimode link between MTRJ-equipped switches, patch panels, and legacy networking hardware.
With support for 1 Gbps Ethernet over typical OM1 distances, this cable is ideal for LANs, data centers, telecom systems, and enterprise networks where MTRJ-terminated equipment must interconnect without additional adapter couplers or extra patch cord runs.
MTRJ-MTRJ Multimode OM1 Ultra Fiber Cable
The MTRJ-MTRJ OM1 cable uses Corning 62.5/125µm multimode optical fiber to provide a robust, duplex connection between MTRJ ports — offering reliable performance for short-range communication in legacy and mixed-generation networks. Each MTRJ connector houses both transmit and receive fibers in a single duplex ferrule, enabling compact, high-density terminations on switches, patch panels, and network appliances.
This direct MTRJ-to-MTRJ assembly eliminates intermediate adapter couplers and additional patch cords — reducing connection points, insertion loss, and cable management complexity wherever MTRJ-terminated equipment needs to be linked over OM1 multimode fiber.

Key Features
- Direct MTRJ-to-MTRJ Cross-Connection Factory-terminated with MTRJ on both End A and End B — eliminating the adapter couplers and extra patch cords that would otherwise be required to bridge MTRJ-terminated equipment, reducing insertion loss and removing additional mechanical joints from the channel.
- Corning 62.5/125µm OM1 Fiber Built on Corning optical fiber — the global standard for long-term transmission reliability. The 62.5µm core supports short-range 1 Gbps Ethernet, making this cable ideal for existing OM1 plant in LANs, data centers, and campus environments.
- Optimized for Legacy Infrastructure MTRJ connectors are installed in a large base of legacy networking equipment worldwide. The MTRJ-MTRJ configuration provides a straightforward way to interconnect MTRJ-equipped switches, media converters, and patch panels — extending infrastructure life without requiring port-by-port hardware replacement.
- Low Insertion Loss Precision-polished MTRJ connectors deliver ≤ 0.3 dB insertion loss (0.2 dB typical) — ensuring strong, stable signal transmission with minimal degradation across the full duplex OM1 channel under all rated operating conditions.
- Compact Duplex Design The MTRJ connector's single-ferrule duplex form factor at both ends houses both transmit and receive fibers in a space-saving footprint — ideal for high-density legacy equipment panels where minimizing connector bulk is a priority.
- Durable Long-Term Performance Rated for 500+ mating cycles with less than 0.2 dB change in insertion loss across an operating range of -40°C to +85°C — engineered for reliable performance in demanding network environments with frequent patching and varying environmental conditions.
Ideal Applications
MTRJ-MTRJ OM1 cables are deployed wherever MTRJ-equipped switches, patch panels, and network devices must connect across short-distance multimode links.
Legacy Infrastructure Upgrades
Connects MTRJ-terminated legacy switches and equipment directly to MTRJ patch panels and distribution frames — deferring full equipment replacement while delivering immediate connectivity improvements.
Data Centers
Bridges MTRJ-equipped legacy infrastructure within racks and rows — simplifying structured cabling where MTRJ patch fields are still in service during phased migration projects.
Local Area Networks
Connects computers, switches, and routers within office LANs and campus environments where both horizontal and backbone cabling are MTRJ-terminated.
Telecom Networks
Used in telecom rooms and networking closets to connect MTRJ-terminated legacy feeder cables to MTRJ distribution panels and multiplexers.
Enterprise Networks
Provides robust connectivity across enterprise departments where MTRJ-equipped workgroup switches and core switches must interconnect over existing OM1 plant.
Government & Regulated Facilities
RoHS-compliant construction and GSA contract availability make MTRJ-MTRJ OM1 cables a direct-procurement option for government facilities maintaining MTRJ-based campus and building networks.
How to Configure Your MTRJ-MTRJ OM1 Assembly
Four decisions define your MTRJ-MTRJ OM1 assembly — use this guide to arrive at the right configuration for your deployment.
Confirm Distance & Bandwidth
OM1 supports 1 Gbps over typical short-range runs. If your links require higher bandwidth or extended distances, consider OM3 or OM4 multimode for 10G, or OS2 singlemode for long-haul applications. Confirm your transceiver specifications before finalizing fiber type — mismatched fiber grades cause link failures that are difficult to diagnose in the field.
Verify Connector Orientation
Confirm that both ends of your run are MTRJ before ordering. If one end uses a different connector type (LC, SC, ST), specify the appropriate MTRJ-to-LC, MTRJ-to-SC, or MTRJ-to-ST assembly instead. For existing runs with adapter couplers, a direct MTRJ-MTRJ cross-cable removes the coupler and reduces insertion loss by ~0.3–0.5 dB per removed joint.
Select Length & Jacket
Available in standard lengths from 0.5m to 15m and custom lengths for special routing. PVC (OFNR) for standard equipment rooms and data center environments, plenum (OFNP) for air-handling spaces and above-ceiling runs, LSZH for facilities with halogen restrictions or European compliance requirements.
Plan for Future Expansion
When planning network growth, consider whether a phased migration away from MTRJ toward LC, SC, or other connector ecosystems is on the roadmap. MTRJ-MTRJ patch cords are an excellent way to maximize existing infrastructure life while you schedule and budget for long-term upgrades.
