In this blog, ETU-LINK will make an inventory of the part numbers and supported transmission distances of 1.25G SFP BiDi Simplex optical modules.

1.25G SFP BiDi Simplex bidirectional optical module supports 1.25Gb/s transmission rate, supports hot swap, Simplex bidirectional transmission, supports temperature range : commercial temperature (0℃～+70℃), extended temperature (-20℃～+85℃) ), and industrial temperature (-40℃～+85℃), with DDM (Digital Diagnostic Monitoring) function.

BiDi Simplex bidirectional optical modules need to be used in pairs. Take a 1.25G BiDi optical module with an extended distance of 80 kilometers as an example. If the wavelength of this end module is TX1490/RX1550nm, then the other end module needs using a wavelength of TX1550nm/RX1490nm, and The 1.25G BiDi optical module with the same transmission distance of 80 kilometers.

The connector types of the 1.25G BiDi optical module include SC and LC . The SC connector needs to be connected to the SC connector patch cord, and the LC connector needs to be connected to the LC connector patch cord.

The above is the 1.25G SFP BiDi Simplex bidirectional optical module that ETU-LINK has listed for you. It is widely used in Gigabit Ethernet and can meet long-distance transmission through Single Mode fiber.
