1G BiDi SFP Transceiver Modules (Set) - Simplex Fiber

The majority of fiber optic cable installed for audio, video, network and control is two strand (duplex) count or greater. This is because most fiber optic electronics, including SFP modules, segregate send and receive signal transmission onto two separate fiber strands. 

Simplex (or one strand) fiber is typically relegated to telecommunications runs, such as ISP feeds outside of a building. However, from time-to-time simplex fiber finds its way into applications where multistrand is required, either from damaged cable or a previously installed or mis-specified cable. 

The TechLogix TL-1GSFP-BD SFP solves this problem by multiplexing duplex communication onto a simplex cable. 

Each TL-1GSFP-BD includes two matching transceivers that feature a single LC connection. The transceivers must be used in pairs and are compatible with standard 1G network switches, media converters and other 1G-based IP devices. 

For added versatility, the TL-1GSFP-BD is compatible with both single mode and multimode fiber. Single mode supports transmission distances up to 6.2 miles, whereas multimode supports transmission distances up to 492 feet.

  • What comes in the package?
    Two TL-1GSFP-BD transceiver modules (matched pair).

    What type of fiber is compatible with my module?
    Simplex single mode or multimode.

    What’s the max length of fiber I can connect to my module?
    10 kilometers (6.2 miles) on OS2 or 150m (492 feet) on OM3.

    What type of connectors are compatible with my module?
    LC connectors.

    Are these modules compatible with other devices or do they have to be used with TechLogix equipment?
    The TL-1GSFP-BD can be used with other equipment, provided it’s compatible with a 1GBASE-LX/LH SFP transceiver.   These transceivers have been tested with network equipment such as Cisco, Arista, Juniper, Dell, Brocade and other brands. However, TechLogix can only warrant performance with compatible TechLogix devices and is not responsible for damage caused by improper installation.
