Ubiquiti UF-SM-10G-S Compatible 10GBASE-BX SFP+ BiDi Transceiver (SMF, 1270nm-TX/1330nm-RX, 10km, LC, DOM)
This Ubiquiti UF-SM-10G-S compatible SFP+ BiDi module supports 10GBASE-BX throughput up to 10km over a single strand of single-mode fiber (SMF). Unlike the regular SFP+, this BiDi transceiver integrates a DFB transmitter and PIN receiver into a simplex LC interface. By utilizing the WDM technology, it supports bidirectional communication by transmitting a 1270nm wavelength and receiving a 1330nm signal simultaneously on the same fiber. This design effectively doubles transmission capacity without requiring new fibers, thereby simplifying cabling installation. As a third-party supplier, OPTCORE provides 10GBASE-BX-U SFP+ BiDi at a very affordable price when compared to the original UF-SM-10G-S. Each transceiver has been coded and passes the test with the 10G SFP+ port of Ubiquiti network switches, routers, servers, and network interface cards (NICs). Please note that this SFP+ BiDi module must be used in pairs with another transceiver of complementary wavelengths.

Key Features
Double Network Capacity without New Fiber Deployment
The regular transceiver requires two fibers to accomplish communications, while the BiDi SFP+ can communicate over just one fiber strand. By switching to a BiDi transceiver, you can instantly double network throughput to 10km with the same fiber infrastructure and finally save 50% on fiber deployment costs.
Intelligent DOM/DDM for Smart Networks
With built-in Digital Optical Monitoring function, the 10G SFP+ BiDi module allows users to monitor the fiber link operating parameters in real-time. That ensures a reliable optical network and helps locate network problems quickly.
Optimal Performance and Quality for 10G Networks
Featuring a built-in Semtec/Macom chip and reliable BOSA with integrated DFB laser + PIN receiver, the BiDi SFP+ module delivers low power consumption (≤1.2W) and stable optical links for 10G Bidirectional networks like 10G Ethernet and Fibre Channel. You can rest assured regarding quality and warranty.
