📊 Key Specifications
Data Rate: Up to 1.25 Gbps (Gigabit Ethernet).
Standard: Complies with IEEE 802.3z / 1000BASE-ZX optical specifications.
Form Factor: SFP (mini-GBIC) — hot-pluggable.
Connector: Duplex LC optical interface.
Fiber Type: Single-mode fiber (SMF).
Wavelength: 1550 nm transmission.
Maximum Reach: ≈80 km (≈50 miles) over SMF.
Transmitter: DFB laser (Distributed Feedback) for long-distance link quality.
Receiver: PIN photodiode with high sensitivity.
Optical Power: Typical transmit power up to ~5 dBm and receive sensitivity better than ~–27 dBm.
Power Consumption: ≤ 1.5 W typical.
Monitoring: Supports Digital Diagnostic Monitoring (DDM/DOM) for real-time optical performance data (check specific module variant — some listings include it).
Operating Conditions: Usually 0 °C to 70 °C; compatible with broad humidity ranges.
📡 Features & Benefits
✔ Long-Distance Fiber Reach: Supports links up to ~80 km, ideal for inter-building and campus backbone connections.
✔ Hot-Pluggable: Easy insertion/removal without powering down equipment, minimizing network disruption.
✔ High Compatibility: Works with many devices that support standard SFP optics and 1000BASE-ZX.
✔ Efficient & Reliable: Low power draw and robust optical performance for professional networking environments.
✔ Monitoring Support: DDM/DOM lets administrators monitor optical signal strength, temperature, and other parameters (where supported).
📍 Typical Use Cases
Backbone connections between campuses or data centers.
Fiber uplinks linking distant switches/routers.
Long-reach Ethernet links where copper or shorter fiber modules can’t reach.
⚠️ Important Notes
✔ Ensure your networking equipment (switch, router, etc.) supports SFP modules and 1000BASE-ZX optics before installing.
✔ Use appropriate single-mode fiber cabling with LC connectors for proper operation.
✔ DDM/DOM capability may vary by specific vendor/model — confirm with the product datasheet.
