Price of Single-Mode Dual-Core Optical Module

Single-Mode Dual-Core Optical Modules typically range from $30 to $200 per module, depending on speed, distance, and vendor. OverviewSingle-Mode Dual-Core optical modules are designed for long-distance fiber optic transmission using two fiber cores, which allows simultaneous bidirectional data transfer or redundancy. They are commonly available in SFP, SFP+, and QSFP form factors, supporting speeds from 1Gbps to 100Gbps.

Single-mode fibers have a smaller core, enabling light to travel in a straight path with minimal signal loss, making them ideal for telecommunications and data center backbone networks.

Typical Price Ranges1

G SFP Single-

Mode Dual-Core Modules: Around $30–$50 per module for standard 1310nm, 20 km reach modules. 10G SFP+ Single-Mode Dual-Core Modules: Typically $80–$150, depending on distance (10–40 km) and vendor. 25G/40G QSFP+ or QSFP28 Single-Mode Dual-Core Modules: Prices can range from $150–$200+, especially for long-haul or DWDM-compatible modules.

Factors Affecting Price

Data Rate: Higher-speed modules (10G, 25G, 40G, 100G) cost more due to advanced electronics and tighter tolerances. Distance: Modules supporting longer distances (20 km, 40 km, 80 km, or DWDM) are more expensive. Vendor and Brand: OEM modules from Cisco, Juniper, or Arista are typically 2–3 times more expensive than third-party compatible modules.

Features: Modules with Digital Diagnostic Monitoring (DDM), low power consumption, or enhanced temperature tolerance may increase cost.

Where to Buy

Amazon: Offers 1. 25G–10G SFP single-mode modules with dual LC connectors, priced around $30–$150 depending on speed and distance. Mouser Electronics: Stocks single-mode 1310 nm transceivers with datasheets and inventory, suitable for enterprise and industrial applications.
