Description
The DONGWE Technologies DW-D4085-01CQ is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+
Transceiver for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range
multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40
Gbps bandwidth. Each lane can operate at 10.3125 Gbps up to 100 m using OM3 fiber or 150 m using OM4 fiber.
These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The
electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO)
connector. This module incorporates DONGWE Technologies proven circuit and VCSEL technology to provide
reliable long life, high performance, and consistent service.
QSFP+ SR4 is one kind of parallel transceiver. VCSEL and PIN array package is key technique, through I2C
system can contact with module.
DIAGNOSTIC MONITORING INTERFACE
Digital diagnostics monitoring function is available on all DONGWE QSFP+ SR4. A 2-wire serial interface
provides user to contact with module.
The structure of the memory is shown in Figure 5. 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.
