QSFPTEK Gigabit SFP to RJ45 SFP, Copper RJ45 Module, SFP-T, 1000BASE-T Transceiver for Netgear, Supermicro, up to 100m

Product Information

Supports 60x50G/25G/10G SFP56 and 4x400G/200G/100G/40G QSFP-DD modules. The switch also supports 10G with QSA on QSFP-DD ports. The 4x10G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 4x10G LR module to four 10GBASE-LR optical interfaces. Cisco’s QSFP-4X10G-LR-S is optimized to guarantee interoperability in 4x10G mode over the full specification range of 10GBASE-LR and the SFP-10/25G-LR-S (in 10G mode). QSFP-4X10G-LR-S does not support FCoE. The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometer over a standard pair of G.652 single-mode fiber with duplex LC connectors. The QSFP-40G-LR4-S module supports 40GBASE Ethernet rate only. The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed in the device. QSFP-40G-LR4-S does not support FCoE.

BX (officially BX10)–1550nm/1310nm, Single Fiber Bi-Directional 100 Mbit SFP Transceivers, paired as BX-U ( blue) and BX-D ( yellow) for uplink and downlink respectively, also for distances up to 10km. Variations of bidirectional SFPs are also manufactured which higher transmit power versions with link length capabilities up to 40km.

A solution for QSFP to RJ45

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.

There are cases where data center ToR switches are 10G SFP+ fiber ports only, legacy equipment has 10GBASE-T RJ45 ports and cable architecture is copper. The requirement is to make a connection between the ToR switch fiber 10G SFP+ port with the equipment RJ45 SFP+ port. Three solutions: 1. Replace the ToR switch with one with 10G RJ45 ports. 2. Use an SFP+ to the RJ45 media converter. 3. Use a 10GBASE-T SFP+ transceiver. Solution 1 is costly and solution 2 is not that stable. T–these modules incorporate significant interface circuitry for Physical Coding Sublayer recoding [25] and can be used only for gigabit Ethernet because of the specific line code. They are not compatible with (or rather: do not have equivalents for) Fibre Channel or SONET. Unlike non-SFP, copper 1000BASE-T ports integrated into most routers and switches, 1000BASE-T SFPs usually cannot operate at 100BASE-TX speeds. Ryan Latchman and Bharat Tailor (January 22, 2008).

We know that in the present market, there are different types of ports for switches, such as RJ45 port, SFP+ port, QSFP port and etc. Generally speaking, the more ports a switch is equipped with, the more devices the switch can be connected to. Different ports enable switches to other devices via fiber or copper. So what are the different between these ports? How should we wire them respectively? How get different ports connected? Here in this article we will mainly focus on QSFP Port and RJ45 Port. QSFP to RJ45: What Is QSFP Port
