The Cisco iTemp 10GBASE DWDM SFP+ Modules are pluggable, temperature-hardened transceiver modules designed to deliver Remote PHY (R-PHY) capability in field or headend environments. They enable plug-and-play configuration of 10-Gbps Ethernet signals for simple configuration of R-PHY devices or shelves. With 40 ITU C-band wavelengths, operators can control cost and wavelength assignments, and match link budgets in their fiber-deep networks.
