SFP (Small Form Factor Pluggable Transceivers) Modules enable mobile (Cellular) radio systems to operate reliably over a single, single mode fibre. with suitable high isolation MUX/DEMUX coupler modules. Typically one system or using CWDM (Coarse Wavelength Division Multiplexing), up to 16 or 18 individual channels can be set up for single fibre working (SFW), between an Exchange and a Radio Tower Site. From an Exchange to a Mobile Base Station, using SFW, several independent RRU modules can be fed. As ADD/DROP MUX/DEMUX couplers can be used on a SF cable route, CWDM systems offer the advantage of being able to connect to RRU’s at several Radio Tower Sites. Typical transmission distances of up to 40km are employed at a 2.5 Gbps or 10 Gbps line speed. A typical optical link power budget of 19 dB is available. System components will operate reliably over a temperature range of – 5oC to + 70oC and 85% RH. SFP used with 10GBASE-ER and 10G Fibre Channel (with/without FEC).
