• FTTH & Broadband Access: Used in central office (CO) switches to provide high-speed internet aggregation for residential or commercial buildings over a single fiber strand.

• Industrial & Utility Monitoring: Perfect for power grid monitoring, traffic control systems, and remote security surveillance where stable, long-distance single-fiber links are required.

• OmniSwitch Stacking & Uplinks: Provides cost-effective 1G uplinks for OmniSwitch 6450/6860 series, ensuring zero-packet loss during high-traffic periods.

FAQ for Alcatel-Lucent  SFP-GIG-BX-U20 Bidirectional SFP Module

Q1:Can I mix HYTOPTODEVICE BiDi SFPs with original Cisco modules? A:Absolutely.HYTOPTODEVICE compatible sfp bidi cisco  is designed to interoperate perfectly with original Cisco GLC-BX-U and GLC-BX-D transceivers. it is  fully verified for various Cisco devices.

Q2:What is BiDi? A:In the field of optical communication, BiDi refers to Bidirectional Small Form-factor Pluggable (BiDi SFP). It is a type of fiber optic transceiver that uses wavelength division multiplexing (WDM) technology to transmit and receive data through a single fiber optic cable, instead of the traditional two fibers (one for transmitting and one for receiving).

Q3:Do I need two GLC-BX-U20 modules to make a link? A:No,You must use one GLC-BX-U20 (uplink) module at one end of the device and another GLC-BX-D20 (downlink) module at the other end. They communicate using opposite wavelengths on the same single fiber optic cable. The same BIDI module cannot be used at either end of the device.

Q4:Can I use this over Multi-Mode Fiber (MMF)? A:No.BiDi sfp module transmit and receive data using single-mode fiber(SMF). you can not transmit  over MMF.

Q5:Does HYTOPTODEVICE bidi sfp modules support DOM (Digital Optical Monitoring)?A:Yes.HYTOPTODEVICE SFP BIDI module absolutely support DOM. you can monitor temperature, laser output power,bias current and received optical power by DOM function.

Q6:What is BiDi SFP? A:BIDI SFP is an abbreviation of Bidirectional Small Form-factor Pluggable. It is fiber optical transceiver that transmit and receive data through a single fiber optic cable by using wavelength division multiplexing (WDM) technology. it was widely applied in optical communications fields.

Q7:Why choose HYTOPTODEVICE for my sfp bidi cisco needs? A:HYTOPTODEVICE bidi sfp transceivers are manufactured using top-tier Tier-1 lasers and are monitored throughout the entire process. Each bidi sfp module undergoes individual testing in a Cisco environment. Our expertise and extensive experience ensure that our bidirectional SFP Cisco-compliant modules natively bypass the "unsupported transceiver" lockout.

Q8:What is the maximum distance bidi sfp supports? A:BiDi SFP is widely used for transmission distances ranging from 1 kilometer to 80 kilometers or more, depending on the module type (e.g., 1.25G, 10G, 25G) and wavelength configuration.

Q9:How many fibers does a BiDi SFP need? A:Bidi sfp transceiver requires only a single fiber. Traditional SFP require two fibers (one for transmitting and one for receiving), but BiDi sfp uses WDM technology to allow different wavelengths to be transmitted and received on the same fiber cable.

Q10:Can I use a BiDi SFP with a standard dual-fiber SFP? A:No,BIDI SFP modules must be used in pairs—one module transmits signals at wavelength A and receives signals at wavelength B on a single fiber cable, while the other module transmits in the opposite direction on the same fiber cable. They cannot be directly connected to a standard two-fiber transceiver.
