Frequently asked questions
How much does the Cisco 40GBase-LR4L QSFP Module for SMF - For Data Networking, Optical Network - 1 x LC Duplex 40GBase-LR4 Network - Optical Fiber - Single-mode - 40 Gigabit Ethernet - 40GBase-LR4 - Hot-swappable (WSP-Q40GLR4L-RF) cost?
Uniqcli sells the WSP-Q40GLR4L-RF for $3,187.81 against a Cisco list price of $4,399.85. Add it to your cart and submit to confirm current pricing, stock, and lead time. Lower pricing is available for volume orders, Government Purchase Card (GPC) buys, and emergency or urgent acquisitions. Free US shipping on orders over $2,500.00.
Is the WSP-Q40GLR4L-RF TAA compliant and available for government and DoD buyers?
It depends on the unit. Cisco manufactures the WSP-Q40GLR4L-RF in several countries, so Trade Agreements Act (TAA) status is decided per part number and production lot. Uniqcli is an authorized Cisco partner: where Cisco offers a TAA-designated version (usually a ++ part number) we quote that, we confirm the country of origin before shipment, and we attach a country-of-origin statement on request. That is how US federal, DoD, state, local, education, and healthcare buyers get an audit-ready file, with Government Purchase Card (GPC) acceptance and FAR-based urgent and emergency acquisition support. Request a TAA-compliant quote for the WSP-Q40GLR4L-RF and a specialist will confirm the TAA option, price, and lead time, usually within one business day.
Can I buy the WSP-Q40GLR4L-RF as a single unit or in volume?
Both. Order a single WSP-Q40GLR4L-RF through the cart, or ask about lower pricing for volume orders, Government Purchase Card (GPC) purchases, and emergency or urgent (FAR-based) acquisitions. There is no payment up front: we confirm availability and the final total before invoicing.
Where can I find the WSP-Q40GLR4L-RF datasheet and specifications?
The specifications section on this page lists the published specs for the WSP-Q40GLR4L-RF, including ports, power, and dimensions where Cisco publishes them. Ask us for the full Cisco datasheet and we will send the current PDF with your quote.
Need the WSP-Q40GLR4L-RF TAA-compliant for federal or DoD?
Cisco builds this model in multiple countries, so TAA status is decided per part number and production lot. Where Cisco offers a TAA-designated version (usually a ++ part number) we quote that, confirm the country of origin before shipment, and attach the paperwork. GPC-payable. Check the TAA line →
