Cisco GLC-BX80-D-I Compatible 1000BASE-BX SFP BiDi Industrial Transceiver (SMF, 1550nm-TX/1490nm-RX, 80km, LC, DOM, -40~85°C)
This Cisco GLC-BX80-D-I compatible 1000BASE-BX80-D SFP BiDi industrial transceiver supports 1G Bi-directional connectivity by using WDM technology. By integrating the 1550nm transmitter and 1490nm receiver into a simplex LC BOSA, it supports 70km to 80km link distance via a single strand of SMF. It operates with half of the fiber cables, which reduces the total cost of fiber cabling infrastructure. As a third-party supplier, OPTCORE provides this SFP BiDi at a very affordable price when compared to the original GLC-BX80-D-I.
Unlike the commercial transceiver, this 1000BASE-BX80-D SFP BiDi industrial transceiver is made with hardened IC and optical components. It also passes extensive high and low temperature tests, allowing it to support an extended industrial temperature range of -40°C to 85°C. Therefore, it is ideal for industrial networks in harsh environments, including telecommunication, data processing and management, industrial and factory automation, machine control, surveillance, mining, oil and gas, rail, intelligent transportation systems (ITSs), and other outdoor applications.

Key Features
Industrial-Grade BiDi SFP for Industrial Gigabit Ethernet
Designed for harsh industrial environments, the 1000BASE-BX80 SFP BiDi provides secure 1G connectivity for industrial automation, manufacturing, security, transportation, oil and gas, mining, and smart cities. Typically used in industrial Ethernet switches, media converters, and routers.

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.

Intelligent DOM/DDM for Reliable Networks
With built-in DOM/DDM function, the 1G SFP BiDi industrial 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.
