SFP-6G31-iLR 6G SFP+ iLR 1310nm 2km LC SMF DDM Transceiver Module

Overview

The SFP-6G31-ILR is a specialized optical transceiver module designed for intermediate-reach applications requiring high-speed data transmission. This 6G SFP+ ILR transceiver capably supports data rates up to 6.25 Gbps over a distance of 2 kilometers. Consequently, it fills a crucial gap between short-reach and long-reach modules, offering a cost-effective solution for specific network architectures like campus backbones or distributed antenna systems.

Engineered for reliability, this module operates at a 1310nm wavelength and utilizes a high-quality laser for stable performance. Furthermore, its compliance with the SFP+ Multi-Source Agreement (MSA) ensures seamless interoperability with a wide range of networking equipment. The module’s hot-pluggable design also allows for effortless installation and replacement without causing network downtime, thereby ensuring operational continuity.

Key Features

• Supports multi-rate data links up to 6.25 Gbps.
• Intermediate-Long Reach (ILR) of up to 2km over single-mode fiber.
• Operates using a reliable 1310nm FP laser transmitter.
• Fitted with a standard duplex LC connector for SMF cabling.
• Includes Digital Diagnostics Monitoring (DDM) for real-time performance tracking.
• Hot-pluggable SFP+ form factor for easy integration.
• Low power consumption for efficient network operation.

Applications

The SFP-6G31-ILR is perfectly suited for applications that require more distance than standard short-reach modules can provide but do not need the full 10km of a long-reach module. For example, it is widely deployed in 6G Fibre Channel SANs, connecting buildings across a campus. Additionally, it is an excellent choice for wireless infrastructure applications, including CPRI and OBSAI links in cellular networks.

Specifications

Advantages

The primary advantage of the SFP-6G31-ILR is its cost-efficiency for 2km link lengths. Instead of overprovisioning a link with a more expensive 10km LR module, this transceiver provides the exact performance required, optimizing the total cost of ownership. Thus, network designers can build more financially efficient and power-conscious networks without compromising on quality or reliability for these specific distances.

Moreover, the integrated DDM functionality provides a significant operational benefit. By enabling real-time monitoring of critical parameters like optical power and temperature, it allows for proactive network management and faster troubleshooting. This capability is essential for maintaining the high availability and performance demanded by modern storage and communication networks.

FAQ (Technical & Product Questions)

1. What does ILR stand for in the SFP-6G31-ILR module?

ILR stands for Intermediate-Long Reach. It signifies that this 6G SFP+ transceiver is designed for distances that are longer than standard short-reach (SR) modules but shorter than typical long-reach (LR) modules, specifically up to 2km.

2. What is the maximum data rate of this transceiver?

The SFP-6G31-ILR supports multi-rate functionality up to a maximum data rate of 6.25 Gbps, making it suitable for applications like 6G Fibre Channel and various CPRI rates.

3. What kind of fiber optic cable should I use with this module?

To achieve the 2km transmission distance, you must use a duplex single-mode fiber (SMF) patch cable (e.g., OS1 or OS2) that is terminated with duplex LC connectors.

4. Can this 6G SFP+ module be used in a 10G SFP+ port?

Yes, this module can physically be plugged into a standard 10G SFP+ port. However, the host device’s port must be configured to support or lock to the 6.25 Gbps rate for it to function correctly.

5. What are the primary applications for a 2km SFP+ module?

The primary applications include 6G Fibre Channel links in campus SANs, CPRI/OBSAI links for wireless infrastructure, and enterprise backbone connections where the required distance is between 300 meters and 2 kilometers.

6. Is the SFP-6G31-ILR module hot-pluggable?

Yes, this module is fully compliant with the SFP+ MSA standard, which means it is hot-pluggable. You can install or remove it from a compatible device without needing to power down the system, preventing network interruption.

7. What does the DDM feature provide?

The Digital Diagnostics Monitoring (DDM) feature gives network administrators access to real-time operating parameters of the module, such as transmit/receive optical power, temperature, and voltage, which is essential for network monitoring and troubleshooting.

8. Why choose an ILR module instead of a standard LR module?

Choosing an ILR (2km) module is more cost-effective and power-efficient if your link distance does not exceed 2km. It avoids the unnecessary expense of a more powerful 10km LR module, perfectly matching the hardware to the specific application requirement.
