SFP 10G LRL (lite version LR 1.4km), SFP 10G LR++ (enhanced versions or 15-20km/30km versions) are all SFP 10 Gigabit Ethernet optical modules, mainly used for single mode fiber long-distance transmission. Their main differences lie in transmission distance, packaging technology, and application scenarios.
The following is a specific comparative analysis:
SFP 10G LRL (10G Lite / Light LR)
CPRI & 10GBASE LR Lite SFP+ usually refers to “lightweight” or simplified 10G LR opitc modules (Limited Range), with a transmission distance of 1-2 km, belonging to the low-cost version of LR.
- Distance: 1.4km for single mode fiber.
- Application: Used for interconnection between campus networks and data centers with shorter distances than standard single mode fiber connections (10km), it is a more cost-effective solution than standard LR.
- Advantage: Lower cost compared to standard LR.
SFP 10G LR++ (Enhanced / Extended LR)
SFP 10G LR++ usually refers to enhanced modules with stronger performance than the standard 10G LR optic (10km), often referred to as the low-end version of 10G ER (Extended Range), or specifically labeled as “LR++”.
- Distance: Single mode fiber can reach up to 20km, 30km, or even further, exceeding the 10km standard of ordinary LR.
- Application: Access to metropolitan area networks (MAN), connection to base station equipment (BBU, RRU), and long-distance transmission across campuses.
- Advantage: Higher transmission power and higher receiving sensitivity.
Comparison Table
| Item | SFP 10G LRL | SFP 10G LR++ |
| Definition | Lite LR / LRM2 | Enhanced/Extended LR |
| Transmission distance | 1~2 km | 20~30 km |
| Wavelength | 1310 nm | 1310 nm or 1550 nm |
| Fiber type | SMF | SMF |
| Main difference | Short distance lightweight | Over medium to long distances exceeding 10km |
How to choose Transceiver SFP 10G LRL or LR++?
The commonly way is to choose SFP+ transceivers according to your project budget, fiber type, transmission distance, and existed optical link device.
- ≤300m: Choose SR or LRM (multimode environment).
- ≤2km: Choose LRM2 or LRL to save costs.
- About 10km: Choose standard LR.
- 10km-30km: Select LR++/ER.
