MikroTik S-35LC20D Compatible 1000BASE-BX SFP BiDi Transceiver (SMF, 1310nm-TX/1550nm-RX, 20km, LC, DOM)

This MikroTik S-35LC20D compatible SFP BiDi module supports 1G Bi-directional connectivity by using WDM technology. By integrating the 1310nm transmitter and 1550nm receiver into a simplex LC interface, it supports 10km to 20km link distance via a single mode fiber (SMF). Compared with a regular SFP, this BiDi transceiver allows end-users to reduce the total cost of fiber cabling infrastructure by requiring only half of the fiber cables. That provides increased transmission capacity and simplifies installation without the need for new fibers. As a third-party supplier, OPTCORE provides this SFP BiDi at a very affordable price when compared to the original S-35LC20D. Most importantly, we code and test each unit to ensure it works with the MikroTik Gigabit Ethernet switches, routers, servers, and NICs.

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 with the same fiber infrastructure, and finally save the fiber deployment cost.
