Good Quality Sfp28 25g - 25GBASE-SR SFP28 850nm 100m Hi-Optel HSFP28-3831 module - Hi-optel
product detail
Descriptions HSFP28-3831 is SFP28 module, which is designed for use in 25Gb/s data rate over multimode fiber. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has built-in dual clock and data recovery (CDR). This module is designed for multi-mode fiber and operates at a nominal wavelength of 850nm.The transmitter section uses a high performance 850nm VCSEL laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector pre-amplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. Features ● Compliant with MSA SFP+ Specification SFF-8402 ● Monitoring Interface Compliant with SFF-8472 ● Single +3.3V Power Supply ● Hot-Pluggable ● Built-in dual CDR ● Up to 28.05 Gb/s Data Links ● Up to 100m on 50/125 um OM4 ● Up to 70m on 50/125 um OM3 ● Very low EMI and excellent ESD protection ● Operating Case Temperature: 0℃~+70℃ ● Power Dissipation < 1.2W ● RoHS Compliant Products Data Field Descriptions The Module provides diagnostic information about the present operating conditions. The transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and alarm/warning threshold data is written during device manufacture. Received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature monitoring all are implemented. The digital diagnostic memory map specific data field define as following. For detail EEPROM information, please refer to the related document of SFF 8472 Rev 12.2.
