A set of economical modules SFP+ 10G 1270/1330NM dedicated for HP/Arub. A set of two single-mode SFP inserts operates bidirectionally on one fiber on wavelengths 1270/1330 nm and on maximum distance  to 20 km. The electrical interface of the SFP 10G fiber optic module complies with the SFI electrical specifications. The receiver converts serial optical data at 10 Gbit/s into PECL/CML serial electrical data. The single-mode SFP insert is equipped with a two-wire serial I2C interface for serial identification, digital diagnostics and module control. The improved digital diagnostics monitoring interface allows  real time access to the SFP optical module, ensuring the monitoring of received optical power, laser beam current, laser output power, etc. Single-mode SFP+ modules work with 10 Gbps Ethernet, routers and SONET/SDH switches, 10G/8.5G/4.25G/2.125G/1.0625G optical channels and other 10 Gbps optical links. SFP+ 1270/1330NM inserts are dedicated for HP/Arub devices.
