General Description
The QSFP28 full-duplex optical module offers 4 independent transmit and receive channels, each capable of 25Gb/s operation for an aggregate data rate of 100Gb/s on 100 meters of OM4 multi-mode fiber.
An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for proper channel to channel alignment. Electrical connection is achieved through an MSA-compliant 38-pin edge type connector.
The module operates by a single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module Present, Reset, Interrupt and Low Power Mode, are available with the modules. A 2-wire serial interface is available to send and receive more complex control signals, and to receive digital diagnostic information. Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.

FAQ
1. Question: Why should I trust HTFuture compatible transceivers?
Answer: Besides the price advantage we have compared to branded transceivers, HTFuture compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.
2. Question: What's the 100G SR4 transceivers max supported distances?
Answer: The 100G-LR4 QSFP transceivers support up to 100m over multimode fibers.
3. Question: Do you offer 100G QSFP28 transeivers that operate at an industrial temperature range?
Answer: Sorry, 100G QSFP28 transceiver that operate at an industrial temperature range are currently not available, but in development. Please stay tuned.
4. Question: Wills it Compatibility with Huawei?
Answer: Yes, it will.
