About this deal
Remember, when discussing the complex and fast signals involved in such technologies, the whole signal path is very important to achieve a functional communication link. This includes everything in the signal's path: The MAC is normally integated into the network device. The transciever may also be integrated or it may be in the form of a module. Integrating the transciever lowers the total per-port cost but reduces flexibility.
A SFP-10G-BXD-I device is always connected to a SFP-10G-BXU-I device with a single strand of standard SMF with an operating transmission range up to 10 km. A SFP-10G-BX40D-I device is always connected to a SFP-10G-BX40U-I device with a single strand of standard SMF with an operating transmission range up to 40 km. The GLC-GE-DR-LX SFP also supports Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage. An SFP module will typically present itself as a little box that you insert into a switch or router. You then connect fibre or copper cables to the SFP module using one of the standard connectors.
1000BASE-T RJ45 SFP Module
Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link
The GLC-BX-D-I and GLC-BX-U-I are the Industrial temperature rated (IND) counterparts of GLC-BX-D and GLC-BX-U SFPS. This allows link operation in harsh environmental conditions where the module case temperature can be in the range -40°C to 85°C. The term " Ethernet cable" is somewhat of a misnomer. You will likely actually be referring to a CAT5, CAT5e, CAT6 or maybe CAT7 cable that is terminated with an RJ-45 on either end. If terminated correctly, these can be used to connect two Ethernet devices that have a common set of supported protocols.The GLC-GE-DR-LX SFP can interoperate with other 100M SFPs/interfaces as long as those are based on 100BASE-LX10 standard. A 5dB attenuator is needed on the path of dual-rate SFP Tx and 100BASE-LX10 interface Rx. No attenuator is needed on the other fiber strand. The 1000BASE-BX-D and 1000BASE-BX-U SFPs, compatible with the IEEE 802.3ah 1000BASE-BX10-D and 1000BASE-BX10-U standards, operate on a single strand of standard SMF. A GLC-BX80-D-I device is always connected to a GLC-BX80-U-I device with a single strand of standard SMF with an operating transmission range up to 80 km.
