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. The power consumption of 10GBASE-T switch is 1.5 to 4 watts per port depending on the distances, while 10GbE SFP switch uses approximately 0.7 watts per port regardless of distances. Moreover, 10G SFP+ switch offers lower latency with about 0.3 microseconds per link. 10GBASE-T switch latency is about 2.6 microseconds per link due to more complex encoding systems within the equipment. With the advantages of low power consumption and latency, 10Gb SFP+ switch is suitable for large high-speed applications. The Cisco 10GBASE-ER Industrial Temperature Module supports a link length of up to 40 kilometers on standard Single-Mode Fiber (SMF, G.652). The SFP-10G-ER-I for Industrial Operating Temperature Range is a multirate 10GBASE-ER, 10GBASE-EW and OTU2/2e module.

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.BX (officially BX10)–1490nm/1310nm, Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as BX-U and BX-D for uplink and downlink respectively, also for distances up to 10km. [21] [22] Variations of bidirectional SFPs are also manufactured which use 1550nm in one direction, and higher transmit power versions with link length capabilities up to 80km.

I need a Layer2/Layer3 10Gb switch with 8 or 12 SFP+ ports and a relatively cheap price, and it must support QinQ, MLAG and STP/RSTP/MSTP. Any suggestions?”

10-Gigabit Switch Models

The Cisco SFP-10G-SR-I is a multirate 10GBASE-SR, 10GBASE-SW and OTU2/2e module for industrial operating temperature range. This module also supports CPRI datarate options 3, 4, 5, 6, 7, 7a, 8. It 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. Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix". Cisco. 19 August 2018 . Retrieved 26 August 2018. LRM, (long reach multi-mode) originally specified in IEEE 802.3aq is a port type for multi-mode fiber and uses 1310nm lasers. Its 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its PMD sublayer in Clause 68. It delivers serialized data at a line rate of 10.3125GBd. [32] 10GBASE-LRM uses electronic dispersion compensation (EDC) for receive equalization. [33]

Note: Parameters are specified over temperature and at end of life unless otherwise noted. When shorter distances of single-mode fiber are used (<40km), an inline optical attenuator must be used to avoid overloading and damaging the receiver.CX4 applications are now commonly achieved using SFP+ Direct Attach and as of 2011 [update], shipments of 10GBASE-CX4 have been very low. [40] SFP+ direct attach [ edit ] Optical modules are connected to a host by either a XAUI, XFI or SerDes Framer Interface (SFI) interface. XENPAK, X2, and XPAK modules use XAUI to connect to their hosts. XAUI (XGXS) uses a four-lane data channel and is specified in IEEE 802.3 Clause 47. XFP modules use a XFI interface and SFP+ modules use an SFI interface. XFI and SFI use a single lane data channel and the 64b/66b encoding specified in IEEE 802.3 Clause 49. Gbit/s The original QSFP document specified four channels carrying Gigabit Ethernet, 4GFC ( FiberChannel), or DDR InfiniBand. [49] 40 Gbit/s (QSFP+) QSFP+ is an evolution of QSFP to support four 10Gbit/s channels carrying 10 Gigabit Ethernet, 10GFC FiberChannel, or QDR InfiniBand. [50] The 4 channels can also be combined into a single 40 Gigabit Ethernet link. 50 Gbit/s (QSFP14) The QSFP14 standard is designed to carry FDR InfiniBand, SAS-3 [51] or 16G Fibre Channel. 100 Gbit/s (QSFP28) The QSFP28 standard [6] is designed to carry 100 Gigabit Ethernet, EDR InfiniBand, or 32G Fibre Channel. Sometimes this transceiver type is also referred to as QSFP100 or 100G QSFP [52] for sake of simplicity. 200 Gbit/s (QSFP56) QSFP56 is designed to carry 200 Gigabit Ethernet, HDR InfiniBand, or 64G Fibre Channel. The biggest enhancement is that QSFP56 uses four-level pulse-amplitude modulation ( PAM-4) instead of non-return-to-zero (NRZ). It uses the same physical specifications as QSFP28 (SFF-8665), with electrical specifications from SFF-8024 [53] and revision 2.10a of SFF-8636. [7] Sometimes this transceiver type is referred to as 200G QSFP [54] for sake of simplicity. a b QSFP-DD MSA (July 26, 2022).

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).

SWITCH MANAGEMENT TYPES BY NETGEAR

Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10GbE defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards [1] so half-duplex operation and repeater hubs do not exist in 10GbE. [2] The first standard for faster 100 Gigabit Ethernet links was approved in 2010. [3]
