TP-LINK GIGABIT WDM MEDIA CNVTR

Seamlessly integrate copper and fiber networks using the TP‑LINK TL‑FC311B‑2. The robust Gigabit WDM Media Converter is ideal for wireless access points, remote surveillance, and business networking applications where fiber installation must be kept to a minimum. It does this by converting electrical impulses via RJ-45 to optical signals via SC fiber.

Key Specifications

• Ports:

1. 1× RJ‑45 port: 10/100/1000 Mbps Auto‑Negotiation, Auto‑MDI/MDIX
2. 1× SC fiber port: supports Gigabit speeds over single‑mode fiber

• WDM (wavelength division multiplexing) fiber technology: RX at 1550 nm, TX at 1310 nm. It uses a single fiber for both transmit and receive directions, reducing the amount of wiring.
• Range of transmission: It reaches up to 2 km via single-mode fiber at 9/125 µm
  IEEE 802.3i/u/ab/z/x protocols for reliable 10/100/1000 Base-T and fiber performance standards compliance
• Power: External adapter 5 V / 0.6 A
• LEDs: PWR and Link/Act indicators for both ports
• Dimensions: Approx. 3.7″ × 2.9″ × 1.1″ (94.5 × 73.0 × 27.0 mm)
• Operating environment:

1. Temperature: 0°C–50°C (32°F–122°F)
2. Storage: ­40°C–70°C
3. Humidity: Operating 10‑90% RH non‑condensing; Storage 5‑90% RH

• Package included:

1. TL‑FC311B‑2 unit
2. External power adapter
3. Installation guide

Feature Highlights

• Gigabit performance: It enables both copper and fiber ports to support a full 1 Gbps throughput.
• WDM Fiber Efficiency: It has lower deployment costs and infrastructure complexity by transmitting and receiving data over a single strand of single-mode fiber.
• Plug-and-play simplicity: Auto-MDI/MDIX and Auto-Negotiation remove the need for manual configuration and crossover cables.
• Deployment options include rack-mountable or standalone in the TP-Link TL-FC1420 chassis with port negotiation capability.
• Diagnostic LEDs: Instant visual indication of link status and activity.

Ideal Use Cases

• Connect remote buildings or security camera systems over single-mode fiber.
• Extend network infrastructure to wireless access points via fiber.
• Bridge copper LAN segments to far-end fiber runs for campus or industrial use.
• Cut civil installation costs in half with WDM deployment, reducing fiber usage.

Technical Insight

The TL‑FC311B‑2 transmits and receives signals at 1310 nm and 1550 nm. It uses a Wavelength Division Multiplexing (WDM) via a single-mode fiber strand. To ensure proper pairing, utilize a TL‑FC311A‑2 module (with reversed wavelengths). Auto duplex negotiation and MDI/MDIX support provide this with all‑around plug‑and‑play fiber converter reliability.
