200Gb/s HDR to 2x100Gb/s HDR100(QSFP56 to 2xQSFP56) MMFActive Optical Splitter Cable

Mellanox® MFS1S50-HxxxE is a QSFP56 VCSEL-based (Vertical Cavity Surface-Emitting Laser), costeffective 200Gb/s to 2 x 100Gb/s active optical splitter cable (AOC) designed for use in 200Gb/s InfiniBand HDR (High Data Rate) systems.

The MFS1S50-HxxxE cable is compliant with SFF-8665 for the QSFP56 pluggable solution. It provides connectivity between system units with a 200Gb/s connector on one side and two separate 100Gb/s connectors on the other side, such as a switch and two servers. The cable connects data signals from each of the 4 MMF (Multi Mode Fiber) pairs on the single QSFP56 end to the dual pair of each of the QSFP56 multiport ends. Each QSFP56 end of the cable comprises an EEPROM providing product and status monitoring information, which can be read by the host system.

Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.

Mellanox’s unique quality active fiber cable solutions provide power-efficient connectivity for data center interconnects. They enable higher port bandwidth, density and configurability at a low cost, and reduced power requirement in the data centers.

Ordering Information

Absolute Maximum Specifications

Absolute maximum ratings are those beyond which damage to the device may occur.

Prolonged operation between the operational specifications and absolute maximum ratings is not intended and may cause permanent device degradation.

Electrostatic Discharge (ESD)

This product is compatible with ESD levels in typical data center operating environments and certified in accordance with the standards listed in the Regulatory Compliance Section. The product is shipped with protective caps on all connectors to protect it during shipping. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the QSFP cage of the server/switch. Hence, standard ESD handling precautions must be observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipment chassis after installation are subject to system level ESD requirements.

Handling and Cleaning

The transceiver can be damaged by exposure to current surges and over voltage events. Take care to restrict exposure to the conditions defined in Absolute Maximum Ratings. Observe normal handling precautions for electrostatic discharge-sensitive devices. The transceiver is shipped with dust caps on both the electrical and the optical port. The cap on the optical port should always be in place when there is no fiber cable connected. The optical connector has a recessed connector surface which is exposed whenever it has no cable nor cap.

Prior to insertion of the fiber cable, clean the cable connector to prevent contamination from it. The dust cap ensures that the optics remain clean and no additional cleaning should be needed. In the event of contamination, standard cleaning tools and methods should be used. Liquids must not be applied.

Interoperability

For configurations tested with the AOCs please refer to the system level product (SLP) qualification report.

Rate Select

The AOC supports rate select, which is controlled by writing to registers 0x57-0x58. Two bits are assigned for each receiver lane in byte 0x57 (87dec, Rxn_Rate_Select) and two bits for each transmitter lane in byte 0x58 (88dec, Txn_Rate_Select) to specify up to four bitrates, as defined in SFF-8636 Rev 2.9.2 Table 6-5 XN_RATE_SELECT ENCODINGS. All four lanes are required to have the same rate select value.

The below table specifies the rate for each rate select setting.
