To begin with, 10G SFP+ optical transceivers are easily available in the market and are now a mature technology. They are not too expensive. 40G/100G optical modules are commonly used in data centres and enterprises around the world for interconnection. The 10G SFP+ modules have many different standards such as SFP-10G-LR, SFP-10G-SR, 10GBASE-LRM SFP+ and 10GBASE-ER SFP+. We have focused on the factors that separate SFP-10G-SR from SFP-10G-LR.

The Cisco 10GBASE-SR module supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000 MHz *km MMF (OM3), up to 300-meter link lengths are possible. Using 4700 MHz *km MMF (OM4), up to 400 meter link lengths are possible. SFP-10G-SR-S does not support FCoE. Multi-mode cable is more complex. It utilizes multiple beams, which bounce diagonally throughout a somewhat larger (62.5 micron) core. The beams are then collected at the receiving end and recombined. This allows multi-mode to achieve high speeds at a lower power use -and usually slightly lower cost- but the nature of the format means that interference and signal degrading become an issue in longer cables. So multi-mode is generally used for Short Reach (SR) applications. ZR is actually an unofficial format, which is not technically part of the IEEE802.3aestandards for networking hardware. It pushes the range of single-mode ER fiber out to 80km, or about 50 miles. Several hardware manufacturers -including Cisco- have their own implementations of ZR, but they aren't necessarily cross-compatible. The SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs 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.The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000MHz *km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz *km MMF (OM4), up to 400m link lengths are possible.

The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF,G.652). Extended warranty (optional): Cisco SFP+ modules can be covered in a Cisco SMARTnet® Service support contract for the Cisco switch or router chassis

The Cisco SFP-10G-SR series has 2 other important modules: the Cisco SFP-10G-SR-X Module and the Cisco SFP-10G-SR-S Module. While the Cisco SFP-10G-SR-S module is a part of the Cisco S-class optics it matches the Cisco SFP-10G-SR module in performance. LRM transceivers are often mistaken for 10GBASE-LR SFP+ optics, but it is not the same. 10GBASE-LRM SFP+ makes use of the 1310nm lasers, however, it has a maximum reach of only 220 m over standard multimode fibers such as OM3/OM4. This transceiver is available in the XFP and SFP+ form factors. The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard Single-Mode Fiber (SMF, G.652). By comparison, standard transceivers are generally restricted to operating temperatures from about 0°C to 70°C (32°Fto 158°F).

The Cisco SFP-10G-ZR-I is a multirate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e module for industrial operating temperature range. The SFP-10G-ZR-I has a limiting electrical interface receiver, which does not require EDC PHY on the host board, it can be plugged into any SFP+ port. It supports link lengths of up to 70 kilometers on standard Single-Mode Fiber (SMF, G.652), assuming a fiber chromatic dispersion of 20ps/(nm *km). This interface is not specified as part of the 10 Gigabit Ethernet standard and is instead built according to Cisco specifications. The SFP-10G-ZR-I has a cold start at -40⁰C; the transceiver will be operational except optical traffic is not supported from -40⁰ to -28⁰C, all other low speed features (DOM, I2C, etc.) are operational. The module is fully operational from -28⁰C to 85⁰C. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. SFP-10G-BX40D-I transmits a 1330-nm channel and receives a 1270-nm signal. The SFP-10G-BX40U-I transmits at a 1270-nm wavelength and receives a 1330-nm signal.
