Price List for 40G Tunable Optical Modules for Data Center Interconnection

40G tunable QSFP+ optical modules typically range from $200 to $1,200 per unit depending on type, reach, and vendor.

Overview of 40G QSFP+ Modules

40G QSFP+ (Quad Small Form-factor Pluggable Plus) modules are widely used for data center interconnection, supporting high-density switching and 40Gbps Ethernet links . They come in several types:

• SR4 (Short Reach): Uses multi-mode fiber (OM3/OM4) for distances up to 100–150m. Ideal for intra-rack or short inter-rack connections .
• CSR4 (Extended Short Reach): Four-channel module with 12-fiber MTP/MPO interface, supporting up to 300m over multi-mode fiber .
• LR4 (Long Reach): Single-mode fiber with LC connectors, supporting distances up to 10km. Suitable for inter-data center links .
• ER4 (Extended Reach): Single-mode fiber for distances up to 40–80km, used for long-haul interconnects .
• Tunable Modules: Allow wavelength adjustment for DWDM applications, providing flexibility in dense wavelength-division multiplexing networks.

Pricing Estimates

While exact prices vary by vendor, brand, and quantity, typical ranges are:

• SR4/CSR4 modules: $200–$400 per unit
• LR4 modules: $400–$800 per unit
• ER4 modules: $800–$1,200 per unit
• Tunable DWDM 40G modules: $900–$1,500 per unit Prices can fluctuate based on OEM compatibility (Cisco, Juniper, Arista), warranty, and bulk purchase discounts .

Recommendations

• For short-distance intra-data center links, SR4 or CSR4 modules are cost-effective.
• For inter-data center connections, LR4 or ER4 modules are recommended.
• For DWDM or tunable wavelength applications, select tunable 40G modules to optimize fiber utilization.
• Always verify OUI and switch compatibility to ensure seamless integration and stable 40Gbps performance . For exact pricing, it is best to request a quote from vendors like FS, FiberMall, QSFPTEK, or Onis Networks, as prices vary with volume, brand, and delivery location.
