Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco is introducing new industrial temperature–rated, 1 Gbps, bidirectional transceivers for network connectivity up to 10 km. The PIDs are GLC-BX-D-I and GLC-BX-U-I. These transceivers enable 1G connectivity over a single fiber in environments that are not temperature controlled. The Cisco® GLC-BX-D-I and U-I transceivers enable connectivity in Industrial Ethernet (IE series) switches and routers for Internet of Things (IoT) applications such as factory floor automation, utility substation automation, and transportation. Additionally, these transceivers are deployed by service providers to enable connectivity in applications such as mobile backhaul (4G, LTE, 5G), residential, and enterprise broadband access.
Cisco PIDs: GLC-BX-D-I and GLC-BX-U-I
Operation of GLC-BX-D-I and GLC-BX-U-I transceivers over single strand of fiber
The GLC-BX-D-I and GLC-BX-U-I bidirectional transceivers offer the following benefits:
● Supports industrial temperature range (IND): –40 to 85°C (–40 to 185°F).
● Doubles the utilization of existing single-mode fibers by separating the transmission wavelengths.
● The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices as depicted above: the GLC-BX-D-I SFP transmits a 1490-nm channel and receives a 1310-nm signal, whereas the GLC-BX-U-I SFP transmits at a 1310-nm wavelength and receives a 1490-nm signal.
● The GLC-BX-D-I and GLC-BX-U-I SFP allow connectivity for up to 10 km over single-strand, single-mode fiber (G.652).
The two new transceivers complete the family of existing 1G Bidi Transceivers.
