Netstar NS‑ER7‑F1‑13T Indoor Reverse‑PoE Switch with Fiber uplink

Here are the detailed specifications for the Netstar NS‑ER7‑F1‑13T (Indoor Reverse‑PoE Switch with fiber uplink):

🔌 Ports & Power

• 7 × 10/100 Mbps RJ‑45 Reverse‑PoE (RPoE) downlinks – power + data in via pins 4/5 (+) and 7/8 (–)
• 1 × 10/100 Mbps IEEE 802.3u Fiber Uplink (SC) port:
  • 13T version: TX 1310 nm / RX 1550 nm
  • 15T version: TX 1550 nm / RX 1310 nm
• 12 V DC output jack (for powering ONU/ONT downstream)

🌐 Network & Switching

• Auto‑MDIX on RJ‑45 ports; store-and-forward switching
• Standards Supported:
  • IEEE 802.3 (10BASE‑T), 802.3u (100BASE‑TX), 802.3x (flow control/back-pressure), 802.3az (Energy Efficiency)
• MAC Table: 1 K dynamic entries; Packet Buffer: 448 Kbit; Max Frame: 1,536 bytes
• Throughput: ~148,800 pps for 100 Mbps ports; ~14,880 pps for 10 Mbps

⚡ Power & Protections

• Powered remotely via PoE injector (24–48 V DC, 0.5–1 A)
• Port-based isolation: downlink ports can’t talk to each other; uplink transmits to all
• Protections: surge, over-voltage, over-current present on all ports
• Cascadable: up to 4 units in a chain for expanded deployments

🛠️ Mechanical & Environmental

• Casing: rugged indoor-grade housing
• Dimensions: approx. 158 × 60 × 50 mm; Weight: ~170–180 g
• Operating Temp: 0 °C to 50 °C; Storage: 0 °C to 75 °C; Humidity: 20–95% non-condensing

✅ Use Cases & Benefits

• Ideal for indoor ONU/CPE deployments where rooftop power isn’t available
• Single-fiber uplink allows centralized fiber input to serve multiple clients
• Enables remote powering and compact installation, saving on UPS and power cabling costs
