Primary Application Scenarios of Cisco Compatible SFP BIDI Transceiver

The cisco compatible sfp bidi module GLC-BX40-DA must be paired with the GLC-BX40-UA.BiDi SFP modules are used in pairs in the below application scenarios, with matching modules of different wavelengths deployed at each end of the link. 

• Enterprise long-distance interconnection: Deploy 40km sfp bidi transceiver for stable links between headquarters and remote branches.
• Campus and cross-building networking: Use single fiber sfp bidi module to save fiber resources for park and campus construction.
• Metropolitan access network deployment: Reliable Cisco compatible sfp bidi transceiver for edge network links.
• Video surveillance transmission: DOM enabled sfp bidi transceiver for steady long-range camera signal delivery.
• Legacy network upgrade: Plug and play sfp bidi for Cisco to expand and update existing network systems.
• Large-scale project supply: Provide bulk sfp bidi transceiver for system integrators and engineering contractors.

Connectivity Solutions(Application)
1.Switch to Switch Link | Paired SFP BiDi Transceiver Interconnection

This 1G sfp bidi transceiver requires two matched modules for single fiber interconnection. Deploy HYTOPTODEVICE GLC-BX40-DA at one end and HYTOPTODEVICE GLC-BX40-UA at the opposite end of the single fiber link. Their complementary 1310nm/1490nm transmit and receive wavelengths work as a full pair to enable bidirectional data transmission over one single-mode fiber, simplifying cabling and delivering stable 40km gigabit connectivity.

2.Link for Switch to Media Converter
Insert the Cisco compatible sfp bidi transceiver into switch SFP port and connect with fiber media converter, realizing 40km long-range network extension. Widely used for remote terminal access and network expansion.
3.Link with Cable Manager & Patch Panel
Match this long range sfp bidi transceiver with patch panels and cable managers to complete standardized cabinet cabling. Neat layout simplifies daily operation and maintenance for enterprise networks.
