Pairing Guidance
Different from traditional dual-fiber optical modules, 10G BiDi SFP+ Transceiver 20km relies on paired complementary wavelengths to establish effective single-fiber links. The Arista SFP-10G-LXRBD-U compatible 1270nm TX/1330nm RX module must be used in pairs with a reverse 1330nm TX/1270nm RX BiDi module at the opposite end of the fiber. Deploying two identical single-wavelength 10G BiDi SFP+ 20km modules will cause complete link failure, and Arista switch CLI cannot accurately identify wavelength mismatch faults, leading to difficult troubleshooting. HYTOPTODEVICE provides pre-matched paired module packages for Arista network projects, standardizing on-site deployment processes and ensuring one-time successful link activation for 20km long-distance single-fiber transmission.

Primary Application Scenarios
“Why is my 10G BiDi link failing to establish a connection?”“Can I mix different speeds or wavelengths on a 10G BiDi fiber line?” Maybe you will encounter the puzzle. the real answer is : For a successful 10G BiDi link, the transceivers at both ends must operate at identical data rates and feature matching, complementary wavelengths; otherwise, the connection will fail.such as matched Tx1270/Rx1330 and Tx1330/Rx1270 10G.
This 10G BiDi SFP+ module must be deployed as a matched pair alongside its complementary reverse-wavelength BiDi counterpart, fitted separately onto the two opposing ends of your single-strand fiber patch cord to establish functional bidirectional 10G data links. Optimized for fiber-restricted network upgrades and limited cable tray deployments, this 10G BiDi SFP+ module maximizes single-fiber bandwidth efficiency while simplifying enterprise network expansion workflows. Below are its most prevalent commercial installation use cases:
- 10G BiDi SFP+ module for multi-building campus single-fiber trunk lines, halving physical fiber deployment costs for long-distance point-to-point enterprise network upgrades using simplex single-strand OS2 optical cable.
- 10G BiDi SFP+ module for top-of-rack switch to server NIC uplink links, creating consistent high-speed 10G single-fiber data connections between core rack aggregation switches and local server network interface cards.
