Dongguan Suwang Hardware Products Co., Ltd.s the demand for bandwidth grows, the need to the single lane speed in a QSFP is now coming to 112Gbps. QSFP112 is the module and cage/connector system based on current QSFP, targeting to support the 112Gb/s per lane speed in a 4x lane QSFP system and to enable the QSFP 400G interconnect ecosystem. This will greatly help the legacy QSFP users upgrade the link bandwidth to 400G per port with lower cost and shorter transition time.
The QSFP112 MSA will define the module and cage/connector form factor to support the 112G-PAM4 electrical and optical signaling, and the increased high power consumption from various types of optical modules. The QSFP112 connectors and cages will be backward compatible with legacy QSFP 40G(4x10G), 100G(4x25G) and 200G(4x56G-PAM4) modules, including optical transceivers and copper cables. The QSFP112 modules will also be able to be accepted by QSFP-DD connector and cage. The QSFP112 will be able to support both optical and copper interfaces, but those physical layer specifications will be done outside of the MSA specification as is usual for form factor MSA specifications.

Since the official release of QSFP112 hardware specification Rev1.0 in June 2021, Dongguan Suwang Hardware Products Co., Ltd. has officially started the planning, design and implementation of the next-generation QSFP112 400G related products. Some downstream large data center suppliers are already planning and launching next-generation QSFP112 400G network-based hardware system solutions, including the design and consideration of single-chip box architecture and optical interconnect solutions. This has prompted the demand for QSFP structural parts, QSFP housings, optical module housings, precision die-casting connector housings, QSFP-DD housings, MINISAS housings, SFP28 housings, and QSFP+ housings, such as electrical connectors, DACs, optical modules, etc.

The Quad Small Form Factor Pluggable 112 (QSFP112) Multi-Source Agreement (MSA) group has officially released the new QSFP112 Specification Rev 1.0. A total of 31 companies have united to support the QSFP112 MSA, addressing the industry’s demand for high-speed, high-density networking solutionsQSFP112 MSA.

As bandwidth requirements escalate, the need for 112 Gb/s per lane within the QSFP form factor has emerged. QSFP112 builds on the existing QSFP module and cage/connector system, designed to support 112 Gb/s per lane in a 4-lane QSFP system and enable the QSFP 400G interconnect ecosystemQSFP112 MSA. This MSA will significantly help legacy QSFP users upgrade link bandwidth to 400G per port with lower costs and shorter transition timesQSFP112 MSA.

The QSFP112 connector adopts a 0.6 mm-pitch SMT pin design, which has gained majority member support by delivering superior signal integrity (SI) performance and greater design margin for the entire linkQSFP112 MSA.
Systems using QSFP112 cages and connectors will be backward-compatible with existing QSFP28/56 modules, while systems designed for QSFP112 modules will interoperate with current QSFP-DD800 cages and connectors.
The specification also fully accounts for cumulative tolerances across different interfaces and modules, providing sufficient margin to ensure connection reliability under worst-case conditions.
QSFP112 is engineered to support optical modules with power up to 20 W for thermal management. Real-world testing of QSFP112 2M DACs confirms the MSA meets IEEE 802.3ck link requirements for 112 Gb/s PAM4 applications. The QSFP112 MSA has also published hardware specifications for QSFP112 2×1 connectors, cages, optical modules, heat sinks, and moreQSFP112 MSA.

The qsfp28 shell produced by Dongguan suwang Hardware Products Co., Ltd. follows the revolution of qsfp28 MSA optics: Data Center
The adoption rate of qsfp28 MSA compatible optics has continued to rise in the past few years. It is predicted that more than half of the data centers will turn to qsfp28 MSA compliant optics. Considering the explosive growth of data, the traditional 10g or even 40g may not be enough. Therefore, qsfp28 MSA will become a new standard. It has the following advantages.
Cost efficiency - qsfp28 MSA optics now provides a compelling price point, providing greater capacity growth. Moreover, it still proves the future of the network with unparalleled bandwidth. The growth of qsfp28 MSA fiber deployment will undoubtedly reduce the cost of 100g fiber.
Speed and capacity - SFP + and qsfp + optics are not enough for data intensive industries. Therefore, qsfp28 MSA optical is specially designed to transmit large amounts of data with ultra-low delay.
Flexibility - 100g will be the preferred technology across long-distance networks. The 100g network can be customized, optimized and easily expanded to adapt to future changes.
Qsfp28 enclosure with qsfp28 MSA compatible optics overview
Qsfp28 MSA fiber usually has the same floor area and panel density as 40g qsfp +. But it is implemented with four 25 Gbps channels. By upgrading the electrical interface, qsfp28 MSA optical can support signals up to 28gbps. Although the qsfp28 transceiver retains all the physical dimensions of its predecessor, its powerful ability to increase density, reduce power consumption and reduce the price per bit exceeds them. Here are some qsfp28 MSA compatible optics for different applications.
Qsfp28 housing is applied to 100g Sr4 qsfp28
The 100g Sr4 qsfp28 is designed to support short-range transmission through multimode fiber. The transceiver module can support 100g transmission up to 70m on OM3 MMF and 100m transmission on OM4 MMF. Through MTP interface, 100g Sr4 qsfp28 MSA complaint module can be realized through 8 optical fibers × 25g bidirectional transmission.
Qsfp28 precision die casting shell applied to 100g qsfp28 LR4
The 100g qsfp28 LR4 is a qsfp28 MSA complaint and is specially designed for long-distance transmission. Qsfp28 LR4 adopts WDM technology for 4 × The four 25g optical signals are transmitted at four different wavelengths. The 100g LR4 qsfp28 module has a duplex LC interface and can realize 100g bidirectional transmission up to 10km through single-mode optical fiber.
Qsfp28 structure is applied to qsfp28 100g psm4
The 100g psm4 is standardized by qsfp28 MSA. It uses four parallel optical fibers (channels) running in each direction, and each channel carries 25g optical transmission. The 100g psm4 module sends signals down to eight optical fiber cables through the MTP interface. The working distance of 100g psm4 is limited to 500m.

Qsfp28 housing is applied to qsfp28 100g dwdm4
The 100g dwdm4 uses WDM technology - an optical multiplexer and demultiplexer to reduce the number of optical fibers to 2. Because it is compatible with qsfp28 MSA, 100g dwdm4 can work on 2 km long single-mode fiber through duplex LC interface. Compared with qsfp28 LR4, it has shorter transmission distance and lower cost.

Qsfp28 housing is applied to qsfp28 MSA compatible cable
In addition to all qsfp28 MSA 100g transceivers mentioned above, high-speed cables are also deployed in the 100g network. The cable can be qsfp28 to 4 SFP 28 copper cable (DAC) or active optical cable (AOC). Qsfp28 to 4 sfp28 DACs provide the lowest cost, up to 3 meters. They are usually used in the racks of data centers or as chassis to chassis interconnects in large switches and routers. Qsfp28 AOC is lighter and can provide a longer extension range, up to 100 meters.
Qsfp28 housing application in conclusion
Qsfp28 MSA compliant 100g optical devices are indispensable components for applying 100g to infrastructure. They can also be easily extended to 100g networks, as simple as 10g. With higher port density, lower power consumption and lower cost, qsfp28 MSA transceiver is an ideal choice for large data centers and future network expansion. Therefore, we can not do without precision design, precision mold, precision casting and standard production. We can find Dongguan Shuwang Hardware Products Co., Ltd!
