A set of economical SFP+ 10G 1270/1330 nm modules specifically designed for HP/Aruba. This set includes two single-mode SFP transceivers that operate bidirectionally on a single fiber at wavelengths of 1270/1330 nm, with a maximum range of 20 km. The electrical interface of the SFP 10G fiber optic module complies with SFI electrical specifications. The receiver converts serial optical data at 10 Gbit/s into PECL/CML serial electrical data. The single-mode SFP transceiver is equipped with a two-wire serial I2C interface for serial identification, digital diagnostics, and module control. The enhanced digital diagnostic monitoring interface allows real-time access to the SFP fiber optic module and ensures monitoring of received optical power, laser current, laser output power, and more. Single-mode SFP+ modules work with 10 Gbps Ethernet, routers, SONET/SDH switches, as well as various optical channels and connections. SFP+ 1270/1330 nm transceivers are intended for HP/Aruba devices.
