Cisco compatible SFP-50G-SR-S Description

SFP-50G-SR-S is a Cisco Compatible 50GBASE-SR SFP56 MSA (Small Form Pluggable 56). Transceiver designed for operation over multi-mode optical fiber. This transceiver has a 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 an 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. This module uses 50Gb/s VSCEL (Vertical Cavity Surface Emitting Laser) (850 nm) transmitters and 50Gb/s PIN photodiode receiver. This Cisco compatible transceiver support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Additionally, for FEC (Forward Error Correction) availability, the Host device need to support the function, which will help receiving side detect and correct bit errors and improve the overall quality of the link. Cisco compatible SFP-50G-SR-S operates in standard 0°-70°C temperature range and has an LC connector. 50GBASE-SR SFP56 MSA supports up to 53.125 Gbps data rate and such applications as 10G Ethernet | 25G Ethernet | 50G Ethernet. 50G-SFP56-100 optical transceiver is a multi-purpose module which can be used in various scenarios in today’s networking environment. Most popular applications are Internet Service Provider (ISP), Fiber to the Home Aggregation and Backbone, Mobile Operator and Data Center Core Networks.

Transceiver is CE/RoHS certified and is compliant with product safety standards. The SFP-50G-SR-S transceiver is fully compliant to SFP56 MSA (Multi Source Agreement), IEEE802.3cd 50GBASE-SR 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 50GBASE-SR SFP56 transceivers in order to make it work in almost any brand of equipment. We will be glad to know your requirements and check out our other 50G SFP56 Transceivers – Contact Us.
