Fiber Optic Module Industrial 100G 40KM QSFP28 Transceiver Duplex LC 1310nm
QSFP LC Transceiver Advantages
► 4 lanes MUX/DEMUX design
► Aggregate bandwidth of > 100Gbps
► Single +3.3V power supply operating
► Support FEC (Forward Error Correction)
100G Ethernet QSFP Module Applications
► Local Area Network (LAN)
► Wide Area Network (WAN)
► Ethernet switches and router applications
Overview
The central wavelengths of the 4 lanes are 1296 nm, 1300 nm, 1305 nm and 1309 nm. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.
Diagnostic Monitoring Interface
Digital diagnostics monitoring function is available on all QSFP28 ER4. A 2-wire serial interface provides user to contact with module. The structure of the memory is shown in flowing. The memory space is arranged into a lower, single page, address space of 128 bytes and multiple upper address space pages. This structure permits timely access to addresses in the lower page, such as Interrupt Flags and Monitors. Less time critical time entries, such as serial ID information and threshold settings, are available with the Page Select function. The interface address used is A0xh and is mainly used for time critical data like interrupt handling in order to enable a one-time-read for all data related to an interrupt situation. After an interrupt, IntL has been asserted, the host can read out the flag field to determine the affected channel and type of flag.
