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 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.

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 last-possible date a routine failure analysis may be performed to determine the cause of hardware product failure or defect. The table outlines the different BASE-T connectivity options using different cable types and reaches. The SFP-10G-T-X will be supported on a variety of Cisco platforms, including NCS 5501, Nexus 9000, and Catalyst ® 9000. However, the maximum power consumption of SFP-10G-T-X (rated 2.5W per port at 30 meters) imposes certain restrictions in deployment. Typically, the SFP+/SFP28 ports on Cisco switches are designed and rated to support transceivers that can dissipate up to 1.5W power. Given the higher power envelope of SFP-10G-T-X, Cisco switches and routers will not be able to fully populate a chassis and deploy all possible ports with the SFP-10G-T-X.

The GLC-BX-D and GLC-BX-U 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. While existing 10GBASE-T switches such as the Cisco ® Nexus N93108TC-FX can provide such connectivity today, the introduction of the SFP+ modular form factor enables variety and flexibility in deployment. Instead of having to deploy a second dedicated 10GBASE-T switch, the SFP+ module can enable Cisco 10G and dual rate 10/25Gbps switches and routers to connect to 10GBASE-T RJ-45 endpoints using CAT6A cables.Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate” 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.

In terms of Cisco original GLC-T vs GLC-TE vs SFP-GE-T transceivers, GLC-T and SFP-GE-T will be End-of-Sale June 1, 2017 and replaced by the GLC-TE. So then you can only buy GLC-TE transceivers from Cisco. If you’re dealing directly with a company like a telecom who specifically requires NEBS compliance, they’ll let you know and you should choose SFP-GE-T. But for most of the networks, GLC-T and GLC-TE transceivers are all you’d need for Gigabit Ethernet, and they cost less as well. Fiberstore (FS.COM) provides all these three SFP modules. We are manufactured to the exact same standards as Cisco’s own brand, and come with true lifetime warranties. Every SFP module in Fiberstore was tested to ensure 100% compatibility, but only cost a small fraction of name-brand alternatives. 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.
