# Product Documentation
# Product Description

100G-QSFP28-100 (100G-SR4) is Multi-Vendor MSA Compatible 100GBASE-SR4-QSFP28 (Quad Small Form-Factor Pluggable 28) SR4 Transceiver designed for operation over multi-mode optical fiber. Module has minimum guaranteed optical budget of 1.9 dB, which in most cases is enough to reach 100 m over OM4 multi-mode fiber, or 70 m over OM3 multi-mode fiber. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. 100G-QSFP28-100 (also known as 100G-SR4 /100GBASE-SR4-QSFP28 / QSFP28-SR4-100G/ QSFP28-100GBASE-SR4) uses 25Gb/s VSCEL (Vertical Cavity Surface Emitting Laser) (850 nm) transmitters and 25Gb/s PIN photodiode receivers. Module support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. 100G-QSFP28-100 (100GBASE-SR4-QSFP28 / QSFP28-SR4-100G) operates in standard 0°-70°C temperature range and has MTP/MPO connector. 100GBASE-SR4 QSFP28 support up to 103.125 Gbps data rate and such applications as 100G Ethernet (103.125 Gbps). 100G-QSFP28-100 optical SR4 transceiver is multi-purpose module which can be used in various scenarios in today’s networking environment. Most popular applications are Internet Service Provider (ISP), Mobile Operator and Data Center Core Networks. For detailed 100GBASE-SR4 specifications, please see the QSFP28-SR4-100G Datasheet.

Transceiver is CE/RoHS certified and is compliant with product safety standards. 100G-QSFP28-100 (100GBASE-SR4-QSFP28 / QSFP28-100GBASE-SR4) Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA), IEEE 802.3bm 100GBASE-SR4 standard. Consequently compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules. However – our technical team has accumulated deep expertise in custom-encoded firmware’s for 100GBASE-SR4 QSFP28 transceiver in order to make it work in almost any brand equipment. We will be glad to know your requirements – Contact Us.


What is QSFP28 SR4?

QSFP28 SR4 is a high speed transceiver that can reach data transmission speeds of up to 100G, over a 100m distance, using 4 lanes of optical transmission. “SR4” indicates “Short-range 4-lane”. It uses the QSFP28 form factor.

What is the range of 100GBASE SR4?

QSFP28 SR4 transceivers can reach 100m over OM4 cable or 70m over OM3.

What type of connector is QSFP 100G SR4?

QSFP 100G SR4 modules use a MTP/MPO 12 connector.

Is QSFP 100G SR4 connector male or female?

To connect a QSFP 100G SR4 transceiver, you’ll need a cable with a female MTP/MPO 12 connector.

What are other popular names QSFP28-SR4-100G is referred to?

QSFP28-SR4-100G transceivers are sometimes also called 100G-SR4, 100GBASE-SR4-QSFP28 or QSFP28-100GBASE-SR4.
