Primary Application Scenarios
“What happens if the modules on each side of my fiber don't match?”“Can I mix different data speeds or wavelengths on a 10G BiDi fiber line?” Maybe you are in the situation. the real answer is : If the modules at either end of your fiber line run at different speeds or don't have matching wavelengths, your 10G BiDi connection won't work. The matched pair should be Tx1270/Rx1330 and Tx1330/Rx1270 10G.
This 10G SFP+ BiDi Transceiver must be deployed in matched pairs with a complementary reverse-wavelength BiDi module, installed separately at both ends of fiber patch cords to build valid bidirectional 10G links. Ideal for fiber-limited network renovation and cable tray shortage scenarios, this 10G SFP+ BiDi Transceiver boosts fiber utilization and simplifies enterprise network expansion. Below are its mainstream commercial deployment scenarios:
- 10G SFP+ BiDi Transceiver for multi-building campus single-fiber backbone, halving fiber deployment costs for long-distance point-to-point enterprise network upgrades with simplex single-strand OS2 fiber.
- 10G SFP+ BiDi Transceiver for TOR switch to server NIC uplink, building stable 10G single-fiber high-speed connections between core rack aggregation switches and local server network interface cards.
- 10G SFP+ BiDi Transceiver for standardized indoor rack structured cabling layout, matching industry cable management norms for server rooms and multi-floor building wiring infrastructure.
- Bulk factory supply commercial grade 10G SFP+ BiDi Transceiver for corporate office network expansion, running stably in climate-controlled indoor cabinets under standard 0~70℃ operating range.
- Cost-saving 10G SFP+ BiDi Transceiver replacement for Huawei OEM optics for ISP FTTB access network construction, cutting large-batch procurement costs compared with high-priced original Huawei optical modules.
