Key Features

1. Ultra-Long Range 120km Transmission

One of the standout features of this module is its extended transmission distance of up to 120 kilometers over single-mode fiber. This makes it a perfect solution for:

• Inter-city or inter-campus links

• Carrier networks

• Data center interconnects (DCIs)

• Large-scale enterprise infrastructures

The long-range capability reduces the need for additional networking hardware, offering cost and infrastructure savings.

2. Dual Fiber Design with LC Duplex Interface

The module uses dual fiber transmission, requiring two strands of single-mode fiber — one for transmitting and the other for receiving data. It features a standard LC duplex connector, ensuring compatibility with existing network hardware and fiber cabling infrastructure.

This design offers high optical performance, stability, and reduced latency for full-duplex communication.

3. Operating at 1550nm Wavelength

The transceiver operates at a 1550nm wavelength, which is optimal for long-distance fiber communications due to its low attenuation and dispersion characteristics. The use of this wavelength ensures clean signal transmission, even over extended distances, minimizing the need for signal repeaters or amplifiers.

4. High-Speed 10Gbps Data Rate

With a line rate of 10.3 Gbps, the module supports a wide array of 10G applications such as:

• 10G Ethernet (10GBASE-ER)

• SONET/SDH (OC-192/STM-64)

• Fibre Channel

• Data Center and Metro Network Transmission

It ensures fast and efficient handling of large data volumes, streaming, and latency-sensitive applications.

5. Digital Diagnostic Monitoring (DDM)

Equipped with Digital Diagnostics Monitoring Interface (DDMI) as per SFF-8472, the transceiver enables network operators to monitor key performance parameters in real-time, including:

• Transmit and receive optical power

• Laser bias current

• Module temperature

• Supply voltage

This enhances operational control, helps with predictive maintenance, and supports proactive network management.

6. Hot-Pluggable SFP+ Form Factor

Its hot-swappable design allows network engineers to plug or remove the transceiver without powering down the network device. This makes maintenance, upgrades, and replacement fast and efficient, reducing network downtime and improving operational flexibility.

7. Low Power Consumption and Heat Dissipation

Despite its long-range capabilities, the module maintains low power consumption, optimizing thermal efficiency within high-density environments such as data centers. It operates efficiently without generating excessive heat, ensuring reliable performance under continuous operation.

8. Wide Compatibility

The module is fully compliant with SFP+ MSA and IEEE 802.3ae, ensuring compatibility with a wide range of switches, routers, and networking equipment from top brands like Cisco, Juniper, MikroTik, Ubiquiti, Huawei, and others.

This compatibility enables seamless integration into existing network infrastructure without additional configuration or modifications.

Use Cases

• Telecommunication Carriers: Long-distance fiber optic connections between base stations or cities.

• ISPs and MSOs: High-speed data transmission over fiber backbone networks.

• Enterprises: Secure and scalable data links between office locations, campuses, or data centers.
