Browse by Product Family

Click through to shop the families that fit your media converters deployment.

Single-Mode Fiber Converters

Long-distance fiber-to-Ethernet adapters supporting single-mode fiber runs up to 80+ km. Essential for campus-wide and regional surveillance networks where multimode distance limits become a bottleneck.

Multimode Fiber Converters

Short- to medium-range fiber converters (up to 2 km typical) using LC or SC connectors. Ideal for building-to-building links and high-EMI industrial environments where Ethernet cable shielding isn't enough.

PoE Media Converters

Fiber-to-Ethernet converters with integrated PoE injection on the Ethernet side. Eliminates the need for separate PoE injectors when extending power and data to remote IP cameras or access readers.

Gigabit & Multi-Speed Converters

100 Mbps, 1 Gbps, and mixed-speed media converters supporting legacy and modern camera bitrates. Choose by target camera resolution and frame-rate requirements.

Industrial Fiber Converters

Hardened media converters with extended temperature ranges, DIN-rail mounting, and redundant power inputs for harsh surveillance sites, utility substations, and outdoor equipment shelters.

Standalone & Wall-Mount Converters

Compact fiber-to-Ethernet units designed for conduit runs, camera pole mounts, and tight cabinet spaces. Reduces cabling clutter and simplifies field installation.

What to Look For When Buying

The decisions that matter most before you spec.

Distance & Fiber Type Selection

Single-mode fiber extends reach beyond 2 km with lower attenuation; multimode is cheaper for short campus runs. Audit your actual camera-to-switch distance before selecting converter type. Multi-site deployments often expose distance miscalculations when adding remote facilities.

PoE Power Continuity Across Fiber Links

Standard media converters do not pass PoE; use integrated PoE converters or add a separate PoE injector on the far end to power remote cameras. Verify PoE budget at both conversion points to prevent power failures. PoE budget miscalculation is a leading cause of system collapse.

Bitrate Throughput & Network Congestion

Confirm your media converter supports the total camera bitrate plus overhead. A 100 Mbps converter becomes a bottleneck with three or more high-resolution cameras. Network collapse at the core switch is often traced to undersized fiber links and converters.

Redundancy & Failover Architecture

Single fiber runs are single points of failure. Deploy dual converters with managed switches supporting spanning-tree or rapid re-convergence to minimize downtime when fiber cuts or converters fail. Industrial converters often support redundant power for greater reliability.

Environmental Hardening for Field Installations

IP67-rated converters, wide temperature ranges (–40°C to +75°C), and fanless operation reduce maintenance in uncontrolled shelters and equipment vaults. Verify connector type (LC vs. SC) matches your existing fiber plant before ordering.

Integration with Existing Brands & Ecosystems

Camera manufacturers like Axis, Hanwha, and i-PRO often publish tested converter pairings. Transition Networks and Pelco converters are widely certified for surveillance-grade reliability and warranty support.

Technology Stack

The specs and acronyms that actually affect media converters performance.

Single-Mode Fiber (SMF)

Narrow-core fiber (9 µm) with low chromatic dispersion, enabling runs of 40–80+ km without signal loss. Required for long campus or regional deployments; more expensive than multimode.

Multimode Fiber (MMF)

Larger core (50/62.5 µm) allowing shorter distances (up to 2 km typical). Cheaper cabling and connectors; standard for building-to-building or in-building backbone links.

LC & SC Connectors

LC (Lucent Connector) is small, push-pull, and common in modern installations; SC is older, screw-type. Ensure your fiber plant uses matching connector types before deployment.

Gigabit Ethernet over Fiber

1000BASE-LX (long-wave, up to 10 km) and 1000BASE-SX (short-wave, up to 550 m) for high-bitrate camera feeds. Backward-compatible with 100 Mbps but verify your switch supports speed negotiation.

PoE Injection at Fiber Boundary

Integrated PoE converters inject power on the Ethernet side after fiber conversion, eliminating mid-span splitter complexity. Verify wattage (passive vs. 802.3at/bt) matches your camera power draw.

Auto MDI/MDI-X & Link Detection

Media converters with auto-sensing prevent cable pinout errors and detect link loss immediately, triggering failover or alerts. Critical for unattended remote sites.

Typical Deployment Scenarios

Campus Security Network (4 Buildings)

Central NVR in Building A connects to three remote camera shelters (Buildings B, C, D) 800 m apart via multimode fiber (LC connectors). Deploy six multimode media converters (one per building entry/exit) plus PoE injectors at each remote shelter to power outdoor PTZ and turret cameras. Use managed switches with ring or redundant topology.

Utility Substation Remote Video (40 km)

Control center 40 km from substation requires high-reliability fiber video link. Deploy dual single-mode converters (primary + standby) with industrial temperature and fanless design, connected via underground single-mode fiber (9 µm). Add gateway routers for secure remote access to captured feed.

High-Speed Traffic Monitoring (Multi-Lane Highway)

Ten ANPR cameras at mile marker 5 sending full-res frames to central database 8 km away. Use gigabit converters (1000BASE-LX) with multimode fiber backbone to handle sustained throughput. Storage throughput becomes critical at scale; confirm your converter and switch support line-rate forwarding.

Access Control Multi-Site Integration (3 Locations)

Three office buildings (500 m, 1.5 km, 3 km from HQ) need real-time credential databases for card readers and intercoms. Deploy multimode converters for <500 m and 1.5 km runs; upgrade to single-mode for the 3 km link. Add extenders if future camera expansion is planned beyond 2 km.

Frequently Asked Questions

Do I need a media converter or just longer Ethernet cable?

Ethernet over copper (Cat6/Cat6a) is limited to ~100 m maximum and loses signal in high-EMI environments (electrical substations, RF transmitters). Fiber extends distance to 2 km (multimode) or 80+ km (single-mode) with immunity to interference. Media converters are mandatory for long-distance surveillance.

Can a standard media converter pass PoE power to remote cameras?

No. Standard fiber converters only carry data. To power remote cameras, use a PoE-enabled media converter or install a separate PoE injector on the Ethernet side after the converter. Always verify the converter's PoE wattage (passive, 30 W, 60 W, 90+ W) matches your camera's draw.

What's the difference between LC and SC fiber connectors?

LC connectors are small, snap-in style and dominate modern installations. SC connectors are larger, screw-type and common in legacy fiber plants. They are not interchangeable—ensure your media converter, fiber plant, and switch ports all use the same connector type before purchase.

Should I use single-mode or multimode fiber for my 2 km campus link?

Multimode fiber is sufficient up to 2 km and costs less. Use single-mode if you need to exceed 2 km, want future-proof expandability, or operate in areas where multimode fiber is unavailable. Check with your fiber contractor on existing plant before specifying converter type.

How do I ensure media converter redundancy if a fiber cut occurs?

Deploy dual converters (primary + backup) on separate fiber strands or physically diverse routes. Configure your managed switches with rapid spanning-tree (RSTP) or link-aggregation to trigger failover within 1–5 seconds. Test failover before deploying.

What specifications matter most when selecting an industrial media converter?

Look for wide temperature range (–40°C to +75°C minimum), fanless operation (no moving parts to fail), redundant power inputs, and DIN-rail mounting. Verify auto MDI/MDI-X detection for cable-agnostic connections. Check how infrastructure robustness prevents downtime during peak incidents.
