The price of an 80 km single-mode, single-fiber SFP module typically ranges from $80 to $250 per unit, depending on data rate, brand, and features.

Overview

Single-mode, single-fiber SFP transceivers are designed for long-distance optical communication over distances up to 80 km using a single strand of fiber. They are commonly used in Gigabit Ethernet, Fast Ethernet, and Fibre Channel networks and employ DFB lasers for reliable transmission at 1550 nm wavelength ( ). These modules are compatible with standard SFP slots and often support digital diagnostics for real-time monitoring ( ).

Price Factors

The cost of an 80 km SFP module depends on several factors:

• Data rate: Modules supporting 1 Gbps (1000BASE-ZX) are generally less expensive than higher-speed 1.25 Gbps or 10 Gbps modules ( ).
• Brand and OEM compatibility: Generic or third-party modules (e.g., OptoSpan, Optcore) are more affordable, typically $80–$150, while OEM-branded modules compatible with Cisco, Juniper, or Brocade can cost $200–$250 or more ( ).
• Connector type: LC, SC, or FC connectors may slightly affect pricing ( ).
• Additional features: Enhanced diagnostics, RoHS compliance, and extended warranty options can increase the price ( ).

Example Modules

• OptoSpan SFP-11D-K080B55: 1G single-fiber bidirectional, 80 km, LC connector, cost-effective for data center and core networks ( ).
• Optcore OSP155-5580xCR: 155 Mbps, 80 km, single-mode fiber, factory-priced with 5-year warranty ( ).
• Optcore OPT1250-5580xxCR: 1.25 Gbps, 80 km, SC/FC/ST connectors, suitable for Gigabit Ethernet and Fibre Channel ( ).
• Primus TRC-4685-GLCZ: 1G 1000BASE-ZX, 80 km, Cisco-compatible, hot-swappable SFP ( ).

Summary

For a single-mode, single-fiber 80 km SFP module, expect a price range of approximately $80 to $250 per unit, with lower prices for generic modules and higher prices for OEM-branded or feature-rich transceivers. When selecting a module, consider data rate, connector type, brand compatibility, and diagnostic features to ensure both performance and cost efficiency.
