The 1.25G SFP BiDi single fiber bidirectional optical module supports a transmission rate of 1.25Gb/s, supports hot swapping, and single fiber bidirectional transmission. The temperature range supported includes commercial grade (0 ℃~+70 ℃), expansion grade (-20 ℃~+85 ℃), industrial grade (-40 ℃~+85 ℃), and DDM digital diagnostic monitoring function.
BiDi single fiber bidirectional optical modules need to be used in pairs, taking the 1.25G BiDi optical module with an extended distance of 80 kilometers as an example. If the wavelength of this module is TX149/RX1550nm, then the other module needs to use a 1.25G BiDi optical module with a wavelength of TX1550nm/RX1490nm and a transmission distance of 80 kilometers.
The interface types of the 1.25G BiDi optical module include SC interface and LC interface. The SC interface needs to be connected to the SC connector fiber optic jumper, while the LC interface needs to be connected to the LC connector fiber optic jumper.
