📈 Key Specifications
Data Rate: Up to 1.25 Gbps (suitable for Gigabit Ethernet).
Standards: Complies with 1000BASE-LH optical standards and relevant SFP MSA specifications (IEEE 802.3 Gigabit Ethernet).
Form Factor: SFP (Small Form-Factor Pluggable), also called mini-GBIC.
Wavelength: 1310 nm for optical transmission.
Fiber Type: Single-Mode Fiber (SMF).
Connector: Duplex LC optical connector.
Maximum Reach: Typically up to 40 km (kilometers) over single-mode fiber.
Transmitter Laser: DFB (Distributed Feedback) type for stable long-reach performance.
Receiver Type: PIN photodiode for incoming signal detection.
Power Consumption: Low (≤ 1.5 W typical).
📡 Features & Benefits
✔ Hot-pluggable: You can insert or remove the module without powering down the device.
✔ Long-Distance Fiber Link: Ideal for backbone links between buildings, campuses, or data centers requiring up to ~40 km connectivity.
✔ Standard Compatible: Conforms to industry standards (SFP MSA, IEEE Gigabit Ethernet).
✔ Efficient & Low-Power: Minimal power use and small form factor make it suitable for high-density network hardware.
📍 Typical Uses
Connecting switches/routers across long distances over single-mode fiber.
Point-to-point fiber links in campus networks.
Fiber uplinks in data centers and enterprise networks.
⚠️ Important Notes
Ensure the network equipment supports SFP modules and is compatible with the specific optical wavelength and link-distance profile before use.
Some equipment may require DDM/DOM support for monitoring optical performance — check your device’s specifications.
