# Product Documentation
# Product Description

Our SWDM4-40-100G-Q28-440 is an Multi-Vendor MSA Compatible 100G QSFP28 (Quad Small Form-Factor Pluggable 28) and 40G QSFP capable SWDM4 Transceiver, operating over multi-mode optical fiber (MMF) with four independent optical communication lanes, separated from each other using SWDM4 technology. This SWDM4 module has a minimum guaranteed optical budget of 2.2 dB, which in most cases is enough to reach the indicated distance using multi-mode cable. The dual rate transceiver is capable of various distances, regarding the fiber type used. For 100Gbps data rate the distance using OM3 is 75m, for OM4 is 100m and OM5 is 150m. For 40Gbs data rate the distance using OM3 is 240m, for OM4 is 350m and OM5 is 440m. 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. SWDM4-40-100G-Q28-440 uses 4×25.78Gbps/4×10.31Gbps SWDM4 channels (850, 880, 910, 940nm) VSCEL laser transmitter, where the SWDM4 technology multiplexes all wavelengths together and transmits the signal over MMF. On the other end SWDM4 technology demultiplexes the signal into 4×25.78Gbps/4×10.31Gbps PIN receiver lanes. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Additionally module supports FEC (Forward Error Correction) function which will help receiving side detect and correct bit errors and improve the overall quality of the link. It operates in Standard 0°-70°C temperature range and has double LC connectors. The SWDM4 QSFP28 supports data rate up to 103.125 Gbps and such applications as 100G Ethernet (103.125 Gbps) and 40G Ethernet (41.2 Gbps). The SWDM4-40-100G-Q28-440 optical transceiver is multi-purpose module used in number of different places in today’s networking environment. Most popular applications are Internet Service Provider (ISP) Fiber to the Home Aggregation and Backbone, Mobile Operator Core Networks and Mobile Backhaul and Data Center networking site interconnections.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. SWDM4-40-100G-Q28-440 Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA), SWDM MSA, IEEE802.3bm CAUI-4 and SFF-8636 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 SWDM4-40-100G-Q28-440 transceiver in order to make it work in almost any brand equipment.
