Sfp 10g lr

When purchasing SFP 10G LR (Long Reach) modules, you must ensure they support a 10Gbps data rate and operate at a 1310nm wavelength. The standard transmission distance should be up to 10km over Single-Mode Fiber (SMF). Additionally, verify that the modules support DDM/DOM (Digital Diagnostic Monitoring), which allows real-time monitoring of parameters like optical output power, input power, temperature, and laser bias current.

Compatibility is the most critical factor. You must specify the Brand Compatibility (EEPROM Coding) required, such as for Cisco, Juniper, Arista, or Huawei. Most professional suppliers on Made-in-China.com can provide multi-code compatibility or 'unlocked' versions. Always request a compatibility test report for your specific switch model before finalizing a bulk order.

To ensure safety and quality, the modules must be compliant with IEEE 802.3ae 10GBASE-LR standards. For global trade, look for CE, FCC, and RoHS certifications. Furthermore, the physical dimensions and electrical interface must strictly adhere to the SFP+ Multi-Source Agreement (MSA) to ensure they fit into any standard SFP+ port.

The primary difference is the Operating Temperature Range. Commercial Grade (COM) typically operates from 0°C to 70°C, suitable for standard data centers. Industrial Grade (IND) is designed for harsh environments, operating from -40°C to 85°C. Choosing the wrong grade can lead to premature laser failure or signal instability.

Optical transceivers often use lasers from major manufacturers like Mitsubishi or Macom. To avoid refurbished units, require the supplier to provide New & Original (N&O) components guarantees. Use Made-in-China.com's Secured Trading services to ensure payment is only released after quality inspection. Requesting a Batch Test Report showing the 'Optical Eye Diagram' is a professional way to verify performance.

The market for 10G LR modules is highly competitive. For orders exceeding 500 units, you should aim for a 15-25% discount compared to sample pricing. Negotiate for tiered pricing based on annual volume rather than a single shipment. Also, ask for free samples for initial compatibility testing, as reputable suppliers usually provide these to serious B2B buyers.

SFP modules are highly sensitive to Static Electricity (ESD) and physical shock. Ensure the supplier uses Anti-Static Trays or individual ESD bags. For international shipping to your country, use Express Air Freight (DHL/FedEx/UPS) to minimize transit time and handling. Ensure the commercial invoice correctly lists the HS Code (typically 851770) to avoid customs delays.

A professional supplier should offer a 3-year to 5-year warranty. Because the failure rate of optical modules often shows up within the first 3 months (infant mortality), ensure the contract includes a 'Defective Exchange Policy' where the supplier covers the shipping cost for replacing units that fail upon arrival (DOA).
