Cost-effective pluggable optical module 40G

40G QSFP+ optical modules are available from multiple vendors, with pricing dependent on type, reach, and connector; quotes can be requested directly from suppliers like FS, FiberMall, DigiKey, and Cisco.

Module Types and Applications40

G pluggable optical modules come in several types, each suited for different distances and fiber types: SR4 (Short Reach): Uses MPO/MTP connectors, suitable for multimode fiber (OM3/OM4), with distances up to 100–150m. Ideal for data center interconnects and switch-to-switch connections. CSR4 (Extended Short Reach): Four-channel module with 12-fiber MTP/MPO interfaces, supporting distances up to 300m over multimode fiber.

LR4 (Long Reach): Uses LC connectors for single-mode fiber, supporting distances up to 10–20km, suitable for inter-data center links.

Bi

Di (Bidirectional): Supports 40G over duplex multimode fiber, useful for fiber plant reuse and migration scenarios. DAC/AOC (Direct Attach Copper / Active Optical Cable): Short-range, cost-effective solutions for rack-to-rack connections. Pricing and VendorsFS: Offers a full range of 40G QSFP+ modules with distances from 150m to 80km.

Pricing is available upon request, and they provide 30-day free returns.

Fiber

Mall: Supplies SR4, CSR4, LR4, and other 40G QSFP+ modules. Prices vary by type and distance; quotes can be requested online.

Digi

Key: Lists general-purpose 40G QSFP+ modules like the MA-CBL-40G-50CM-HPC, with datasheets and pricing available directly on the product page. Cisco: Offers brand-specific 40G modules for QSFP and QSFP+ ports. Pricing and availability require a quote request, which ensures compatibility with Cisco platforms.

How to Obtain a QuoteSelect the module type based on your fiber type, distance, and connector requirements. Visit the vendor website (FS, FiberMall, DigiKey, Cisco) and locate the specific 40G QSFP+ module. Request a quote via the online form or contact sales directly.

Include quantity, delivery location, and any OEM/ODM requirements. Compare options for warranty, lead time, and shipping. Many vendors offer international express delivery within 3–7 days.

By following these steps, you can obtain an accurate price quote tailored to your network requirements and location.
