Cisco 40GBASE-ER4 QSFP+ Transceiver Module, Single-Mode 40 km

Quantity (units)
Overview
For 40GbE links that must travel 40 km, the Cisco QSFP-40G-ER4 is the module in this list. It is a 40GBASE-ER4 transceiver in the QSFP+ form factor, using a duplex LC connector over single-mode fiber at 1310 nm.
Links of this length connect distant sites or carry traffic across a region. Because losses add up over distance, check the attenuation of your fiber route before you order. The reach is 40 km.
The module is available new or refurbished, with a 1 year or 3 years warranty on each. No used offer is listed. If you are matching a module on an existing circuit, give us the part number of the one at the other end and we will confirm the pairing.
