Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Use industrial temperature (iTemp) Dense Wavelength-Division Multiplexing (DWDM) SFP+ modules to integrate baseband digital DWDM transport into your R-PHY shelf blades, RPDs, or digital PICs.
The Cisco® iTemp 10GBASE DWDM SFP+ Modules (Figure 1) 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. There are 2 types of 10GBASE DWDM SFP+ modules, one tunable module and 3 reaches of fixed wavelength modules. The fixed wavelength modules have With 40 ITU C-band wavelengths and three different distance values available. The tunable module has 70km reach, and 96 50Ghz ITU C-band wavelengths it can be tuned to. Operators can control cost and wavelength assignments, and match link budgets in their fiber-deep networks. The standards-based SFP+ devices are compatible with existing passive filters and splitters, speeding deployments and minimizing service disruptions.
Cisco DWDM SFP+ Module
The Cisco iTemp 10GBASE Dense Wavelength-Division Multiplexing SFP+ Fixed Wavelength Modules offers the following features and benefits:
● Supports 10-Gigabit LAN PHY data rates (10.3125 Gbps) for IEEE Ethernet compatibility.
● Industrial temperature range of operation from -40°C to 85°C
● Hot-swappable transceiver plugs into remote PHY devices, converged broadband-8 (cBR-8) Digital Physical Interface Card (D-PIC), and a variety of Cisco switches or routers in common usage.
● Support for a pay-as-you-grow model for investment protection.
● Standard digital diagnostics capability for incorporation into network management systems.
● Multi-Source Agreement (MSA)-compliant physical form factor for compatibility with a broad range of available products.
● DWDM fixed-wavelength modules support International Telecommunication Union (ITU) 100-GHz spaced channels (ITU 20—ITU 59)Dispersion-tolerant link lengths without added dispersion compensation; up to 80 km supported.
● Supports the Cisco Quality Identification (ID) feature, enabling a Cisco switch or router to identify that the SFP+ module is tested and certified by Cisco.
The Cisco iTemp 10GBASE Dense Wavelength-Division Multiplexing SFP+ Tunable Module, DWDM-SFP10G-C-I offers the following features and benefits
● The DWDM-SFP10G-C-I has a limiting electrical interface receiver, which does not require EDC PHY on the host board.
● The DWDM-SFP10G-C-I can be plugged into any SFP+ port.
● DWDM tunable wavelength module supports 96 tunable ITU 50Ghz spaced channels.
● Reach of 70km, assuming fiber chromatic dispersion of 20ps/(nm*km).
● Tunability enables minized inventory and simplified, rapid deployment.
