Cisco quality Identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco The GLC-GE-DR-LX SFP can interoperate with other 1G SFPs/interfaces as long as those are based on 1000BASE-LX/LH standard. No attenuator is needed in any fiber strand. One thing I did not like is they used 9v power adapters instead of the more standard 12v power adapters. I really wish manufacturers would just standardize on the 12v 2A power adapter and not try shaving every last ounce they can off the power supplies. The power adapter wall warts are prone to being spiked and have a much higher failure rate than the devices they power so you have to assume that at some point you are going to have a wall wart failure. Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link In summary, SFP, DOCSIS, and Ethernet are all standards for transmitting data over a physical medium. The standards will often dictate physical aspects of the interface - for example SFP specifies the size and shape of a module, while DOCSIS and Ethernet specify the requirements of the cable.
As @JourneymanGeek points out, Ethernet specifies what signals to transmit and receive, and puts requirements on the characteristics of the cable - certain signal loss is acceptable at certain frequencies, and certain inter-pair cross-talk levels (where the signals on one pair can be " heard" on another pair).

Why Choose RJ45 SFP Module Over Optical SFP Module?
Transceiver module, known as the essential optics for data transmission, is widely used to connect network applications like switches and network interface cards. Various types of transceiver modules exist, such as copper SFP, fiber SFP, CWDM SFP and so on. RJ45 SFP module is a kind of transceiver modules, which has been utilized as a legacy solution for some years. This article will give a clear explanation to RJ45 SFP module, its benefits and how to use it. What Is RJ45 SFP Module? Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch (no need to power down if installing or replacing) DOCSIS outlines requirements for the signals and cable, but I don't believe it dictates the termination / connectors. In the UK these are typically terminated with F-Type Coax connectors. The SFP+ to RJ45 solution is to use an SFP+ 10G RJ45 transceiver as an adapter for the SFP+ port and then connect a Cat6/7 cable from the server/storage side to the RJ45 connector of the SFP+ transceiver. It is a much cheaper solution than replacing a new RJ45 to SFP+ switch, and more flexible and less lossy than RJ45 to SFP+ media converters. 4 Factors to Consider When Choosing SFP+ to RJ45 Solution The dual-rate 100M/1G 10Km SFP is interoperable with the IEEE 100BASE-LX and 1000BASE-LX/LH standards.
When shorter distances of Single-Mode Fiber (SMF) are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP at each end of the link whenever the fiber-optic cable span loss is less than 8 dB. The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW, and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF,G.652). 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. Bought 2 of these to upgrade a fiber link - however a week after they arrived a power supply running a different fiber transceiver on a different link died and I ended up using these to replace that set. They were a drop in replacement for the failed set so it was very timely that I got them. Also each transceiver appears to act as a switch since one of the transceivers is plugged into a 100baseT port while the other one is plugged into a gigabit switch port. I assume the fiber line that came up between the transceivers is running at gigabit.The Cisco 1-Gbps SFPs are supported across a variety of Cisco networking equipment *.

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.
How to Use RJ45 SFP Module?
Cable Internet" is a consumer term that typically refers to transmitting data via a coaxial cable using a version of DOCSIS.
The Cisco 10GBASE-LR module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF) (G.652). SFP-10G-LR-S does not support FCoE. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. The GLC-BX80-D-I and GLC-BX80-U-I SFPs also support 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.
What Is RJ45 SFP Module?
A GLC-BX40-D-I or GLC-BX40-DA-I device connects to a GLC-BX40-U-I device with a single strand of standard SMF with an operating transmission range up to 40 km. 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. However, they do exist as "Direct Attach Cables". In this form, the modules are attached to either end of the cable, and are not designed to be removed. 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:
