# Product Documentation
# Product Description

100G-QSFP28-10RX is Multi-Vendor MSA Compatible 100GBASE-LR4 Rx Only QSFP28 (Quad Small Form-Factor Pluggable 28) Transceiver. As global online traffic is asymmetrical – especially this statement is valid nowadays when biggest share of global traffic is video streaming, there is much more downlink traffic then uplink. To address this challenge and help engineers design networks more cost efficiently 100GBASE-LR4 Rx Only comes in play. 100GBASE-LR4 Rx Only doesn’t have 4x25Gb/s TOSA transmitters, it only has 4x25Gb/s PIN ROSA receivers comparing to classical 100GBASE-LR4 module which has both components – 4x25Gb/s TOSA transmitters and 4x25Gb/s PIN ROSA receivers. With help of that 100GBASE-LR4 Rx Only becomes cost efficient alternative comparing to classical 100GBASE-LR4 and can be used in network scenario in combination with 100GBASE-LR4 to make most optimal 100G connections according to real requirements for downlink and uplink in your network. Module operates over one single-mode optical fiber where it receives four independent optical communication lanes, separated from each other using LAN WDM technology. Module has guaranteed average receiver sensitivity for each lane: -10.6 dBm, which in most cases is enough to receive signal from 10 km distance using single-mode cable. 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. Module support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. 100G-QSFP28-10RX operates in Standard 0°-70°C temperature range and has single LC connector. 100GBASE-LR4 Rx Only QSFP28 support up to 103.125-112.2 Gbps data rate and such applications as 100G Ethernet (103.125Gbps), Optical Transport Network OTU4 4l1-9D1F (112 Gbps) and 128G Fiber Channel (112.2 Gbps). 100G-QSFP28-10RX 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), Mobile Operator and Data Center Backbone and Core networks to address traffic asymmetry challenge, and as well can be used in networking scenarios where Deep Packet Inspection (DPI) is performed.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. 100G-QSFP28-10RX Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA), IEEE 802.3ba 100GBASE-LR4 and IEEE 802.3bm, Optical Transport Network OTU4 4l1-9D1F and 128G Generation 6 Fiber Channel standards. 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-LR4 Rx Only QSFP28 transceiver in order to make it work in almost any brand equipment. We will be glad to know your requirements.
