Cisco 100Gbps 100GBase-ER4 Single-mode Fiber 10km 1310nm Duplex SC Connector CPAK Transceiver Module – CPAK-100G-ER4L

Cisco CPAK-100G-ER4L 100GBASE-ER4 CPAK Transceiver

Extend compatible 100GbE network links over single-mode fiber with the Cisco CPAK-100G-ER4L transceiver module. This CPAK optic is specified for 100GBASE-ER4 operation, a 10km reach, 1310nm wavelength, and a duplex SC connector, providing the key attributes needed for longer-distance network planning. It is suited to service-provider, campus, data-center, and backbone links where the host hardware and fiber path support the CPAK format. Verify the transceiver bay, fiber plant, connector arrangement, distance, and optical budget before installation.
