Cisco 40GBASE-LR4 QSFP+ Transceiver Module, Single-Mode 10 km, Enterprise Class
QSFP-40G-LR4-S · Refurbished · 1 year warranty
Quantity (units)
Overview
Ten kilometers is the working distance of the Cisco QSFP-40G-LR4-S. This enterprise-class 40GBASE-LR4 module comes in the QSFP+ format with a duplex LC connector, 1310 nm wavelength and single-mode fiber.
It is a natural fit for 40GbE links between buildings on a campus or across a metro fiber ring. Since it is single-mode, the far-end module must also be single-mode and at a compatible rate; a multimode port will not connect to it.
Offered new and refurbished only, each with a choice of 1 year or 3 years of warranty. No used units are listed for this part number. Send the quantity and the switch model you will use it in, and we will check stock and reply with pricing.
