AI Overview
An "Extreme SFP 1.25G 80km" refers to
a Small Form-factor Pluggable (SFP) transceiver module designed for long-distance, 1 Gigabit (1.25Gbps) Ethernet links, typically using 1550nm wavelength on single-mode fiber (SMF) for distances up to 80 kilometers, often compatible with Extreme Networks gear and standards like 1000BASE-ZX, featuring duplex LC connectors and Digital Diagnostics Monitoring (DDM) for network management. These modules are crucial for extending networks across large campuses, metro areas, or connecting remote sites. Key Characteristics:
- Data Rate: 1.25 Gbps (Gigabit Ethernet).
- Reach: Up to 80 km (kilometers).
- Fiber Type: Single-Mode Fiber (SMF).
- Wavelength: Commonly 1550nm (for long reach).
- Interface: Duplex LC connector.
- Compatibility: Designed to work with Extreme Networks equipment (e.g., Extreme 10053 series) and other MSA-compliant devices.
- Technology: Uses DFB lasers and PIN photodiodes for transmission.
- Monitoring: Supports DDM/DOM (Digital Diagnostics Monitoring) for real-time status.
Common Types & Variations:
- 1000BASE-ZX: Standard for long-reach 1G links, often 80km.
- CWDM (Coarse Wavelength Division Multiplexing): Uses specific wavelengths (e.g., 1270nm, 1470nm) for DWDM systems, also available in 80km versions.
- BiDi (Bidirectional): Uses a single fiber strand with different wavelengths for transmit/receive (e.g., 1310nm/1490nm), also available in 80km.
In essence, it's a reliable, cost-effective transceiver for long-haul 1G fiber connections, often a third-party, compatible version of Extreme's OEM modules, offering significant savings while maintaining high performance, notes.

What SFP is required for long distance connection?
Key Long-Distance SFP Types
- LR (Long Range): Standard for 10km links over SMF; common for large buildings or campus networks.
- ER (Extended Range): For longer distances, typically up to 40km, also on SMF.
- ZR (Very Long Range): For ultra-long haul, often up to 80km on SMF.
- LX (Long Wavelength): Another term for longer-reach SMF SFPs (e.g., 10km).
How to Choose
- Distance: Determine how far the signal needs to travel (10km, 40km, 80km+).
- Fiber Type: Always use Single-Mode Fiber (SMF) for long distances; Multimode is for short distances (meters/hundreds of meters).
- Speed: Ensure the SFP matches your port speed (e.g., SFP for 1G, SFP+ for 10G, SFP28 for 25G).
- Application: LR for campus/metro, ER/ZR for WAN/ISP links.
In summary: Look for SMF LR, ER, or ZR modules for distances beyond a few kilometers, using the appropriate SFP/SFP+ form factor for your data rate.

What is the difference between SFP and SFP+?
This video explains the key differences between SFP and SFP+ transceivers:
AddOn Networks
YouTube · Aug 31, 2020
SFP (Small Form-factor Pluggable)
- Data Rate: Up to 1 Gbps (1000 Mbps).
- Applications: Standard Gigabit Ethernet (1000Base).
- Compatibility: Can be plugged into an SFP+ port, but the link speed will be limited to 1 Gbps.
SFP+ (Enhanced Small Form-factor Pluggable)
- Data Rate: Up to 10 Gbps (with support for 8G, 10G, 16G variants).
- Applications: 10 Gigabit Ethernet, 8G Fibre Channel, OTU2.
- Compatibility: SFP+ ports can accept SFP modules (running at 1Gbps), but SFP ports cannot accept SFP+ modules.
This video demonstrates the use of SFP+ modules at 1 Gbps:
Gadgets of TM
YouTube · Jul 26, 2023
Key Differences at a Glance
- Speed: SFP+ is faster (10G) than SFP (1G).
- Form Factor: Same physical size and appearance.
- Standards: SFP (IEEE 802.3), SFP+ (SFF-8431).
- Cost: SFP+ is generally more expensive due to higher performance.
- Use Case: SFP for basic gigabit, SFP+ for higher-bandwidth needs like data centers.

What is the maximum distance for SFP?
SFP maximum distance varies wildly, from under 1 meter (copper) to over 100 kilometers (long-reach optical), depending on module type (SX, LX, ZX), data rate (1G, 10G, 25G+), fiber type (multi-mode vs. single-mode), and wavelength, with common 1G SFPs reaching 10km (LX) and 10G SFP+ reaching up to 80km or more (ER/ZR). Copper SFPs (1000BASE-T) top out at 100m, while Multi-mode (MMF) SFPs usually max out around 550m, and Single-mode (SMF) SFPs handle the longest distances.
Typical SFP Distance Ranges:
- Copper (1000BASE-T): Up to 100 meters (using Cat5e/Cat6).
- Multi-Mode Fiber (MMF - SX): Up to 550 meters (850nm wavelength) for 1Gbps.
- Single-Mode Fiber (SMF - LX/LH): Up to 10 kilometers (1310nm) for 1Gbps.
- Extended Range (EX/ZX): Up to 40km (EX) or 80km (ZX) for 1Gbps over SMF.
For 10G (SFP+):
- Short Reach (SR): A few hundred meters over MMF.
- Long Reach (LR): Up to 10 kilometers over SMF.
- Extended/Long-Haul (ER/ZR): 40km, 80km, 100km, or even 120km+ over SMF for specialized modules.
Key Factors:
- Media: Multi-mode fiber for short links; Single-mode for long distances.
- Wavelength: 850nm (MMF), 1310nm (SMF), 1550nm (Longer SMF).
- Module Type: SX, LX, EX, ZX, LR, ER, etc., each defining distance/fiber.
In short, check the specific SFP module's datasheet (e.g., SFP-10G-LR vs. SFP-10G-SR) and your fiber type for the precise range.
