OEMfibers.com Supply high quality SFP, 10G SFP+, 40G QSFP, CFP, DWDM/CWDM Modules

The rapid growth of server, network, and internet traffic drives the need for higher data rate, higher density, and lower cost optical fiber Ethernet solutions, especially in data centers. As 10 Gbit/s speed is not fast enough to some enterprises, the IEEE 802.3 working group put up the 802.3ba standard of 40 and 100 Gbit/s. For 40G port types, there are 40G-CR4, 40G-KR4, 40GBASE-SR4, 40GBASE-LR4, 40GBASE-ER4, 40G-FR, 40GBASE-T. As speed and performance needs increase, optical transceivers have become an integral part of overall system design. The transceiver supporting 40G is called the Quad Form-factor Pluggable module. This article will introduce something about QSFP-40G-SR4. 40GBASE-SR4 ("short range") is a port type for multi-mode fiber and uses 850nm lasers. It's used for short range fiber connection. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 82 and its Physical Medium Dependent PMD in Clause 86. It uses four lanes of multi-mode fibe...

40GBASE-LR4 QSFP+ transceivers use two links: coarse wavelength division multiplexing (CWDM) and the other is parallel single-mode fiber (PSM). Do you know what their differences are? There are 40GBASE-SR4 QSFP+ transceivers and 40GBASE-LR4 QSFP+ transceivers . It’s known that 40GBASE-SR4 uses a parallel multimode fiber (MMF) link to achieve 40G. It offers 4 independent transmit and receive channels, each capable of 10G operation for an aggregate data rate of 40G over 100 meters of OM3 MMF or 150 meters of OM4 MMF. While for 40GBASE-LR4 QSFP+ transceivers, there are two kinds of links. One is coarse wavelength division multiplexing (CWDM) and the other is parallel single-mode fiber (PSM). What’s the difference? 40GBASE-LR4 CWDM QSFP+ Transceiver QSFP-40GE-LR4, one of 40GBASE-LR4 CWDM QSFP+ transceivers, is compliant to 40GBASE-LR4 of the IEEE P802.3ba standard. The optical interface is a duplex LC connector. It can support transmission distance up to 10 km over single-mode fiber ...

1.Can the optical transceiver support full-duplex and half-duplex? At present, chips on the market can only use full-duplex environment and can't support half-duplex, such as switching to other brands (SWITCH) or hubs (HUB), and it uses half-duplex mode, which will cause serious conflict and packet loss. 2.Have you done connection testing with other optical transceivers? At present, there are many optical transceivers on the market. If the compatibility of different brands of transceivers has not been tested beforehand, it will also cause packet loss, transmission time is too long, fast and slow. 3. Is there a safety device to prevent packet loss? In order to reduce the cost of optical transceiver, some manufacturers use Register data transmission mode outward. The biggest disadvantage of this mode is that the transmission is unstable and packet loss. The best way is to use buffer line design.which can safely avoid data loss. 4. Temperature adaptability? When the opti...

A common SFP modules usually has two ports, one is TX port for transmitting signals, the other is RX port for receiving signals. Unlike the common SFP modules, BiDi SFP modules has only one port and uses the whole WDM coupler to transmit and receive signals on a single optical fiber. SFP modules must be used in pairs. Common SFP optical transceivers, we should connect two SFP optical transceivers with the same wavelength. For example, if we use 850 nm SFP on one port.We need use 850 nm SFP on the other port. For BiDi SFP optical module, because it transmits and receives signals at different wavelengths, we should connect two BiDi SFPs with opposite wavelengths. For example, if we use TX1310/RX1550nm BiDi SFP on one port.We should use TX1550/RX1310nm BiDi SFP on the other port. OEMfibers.com provides a variety of BiDi SFP optical transceivers. They support different data transmission rates and support transmission distances up to 160 km.Which can meet the needs of today's ind...

Step 1 Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis. Step 2 Remove the SFP transceiver module from its protective packaging. Note Do not remove the optical bore dust plugs until directed to do so later in the procedure. Step 3 Check the label on the SFP transceiver module body to verify that you have the correct model for your network. Step 4 Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver module. Note On some SFP transceiver modules, the TX and RX marking might be replaced by arrowheads pointing from the SFP transceiver module connector (transmit direction or TX) and toward the connector (receive direction or RX). Step 5 Position the SFP transceiver module in front of the socket opening. Note Different Cisco devices have different SFP module socket configurations. Your Cisco device could have either a latch-up or a latch-down orientation. Ensure t...

In the 10 Gigabit Ethernet world, fiber optical transceivers have been developed along the way to meet the increasing usage and demand for higher-performance servers, storage and interconnects. XENPAK was the first MSA for 10GE and had the largest form factor. X2 and XPAK were later competing standards with smaller form factors. XFP came after X2 and XPAK. Then smaller SFP (small form-factor pluggable) enabling greater port density followed the XFP. The newest module standard is the enhanced small form-factor pluggable transceiver (SFP+), which has become the most popular socket on 10GE systems. What Is SFP+ The small form-factor pluggable plus (SFP+) can be referred to as an enhanced version of the SFP that supports data rates up to 16 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ supports 8Gbit/s Fiber Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format suppo...

SFP optical module contains many precise optical components and circuit components, we need to operate in accordance with the specifications, otherwise it is easy to cause damage to the optical module. We will introduce several methods of daily maintenance of optical modules for you. First, ESD protection should be kept in mind We must a good job of electrostatic protection (e.g. wearing anti-static gloves and anti-static bracelets to prevent electrostatic damage), try to contact the light module shell, instead of the contact light module PIN foot; Maintain the humidity of the light module at 30-75% RH. It is strictly forbidden to carry out live plug-and-pull operation on non-hot plug-in equipment. Secondly, the protection of smooth port should be paid attention to. Be sure to keep the end of the optical fiber connector clean. Optical module light outlet avoids long exposure. When not in use, cover the light plug. When not in use, the light plug is stored in a dustproof c...

SFP optical transceivers is packaged in hot-swap small package. At present, the highest speed can reach 10G, and there are many LC interfaces. SFP is abbreviated as SmallForm-factorPluggable, which can be simply understood as an upgraded version of GBIC. The volume of 1000base SFP transceivers is half that of GBIC optical transceivers, and more than twice the number of ports can be configured on the same panel. 1. Turn up the pulling ring of SFP optical transceivers vertically, clamp the top buckle, and gently push the SFP optical transceivers side into the SFP slot by hand until the SFP Transceivers is in close contact with the slot (you can feel the elastic pieces at the top and bottom of the SFP optical transceivers clamping the SFP slot). 2. Wear anti-static wrist when installing/pulling out SFP optical transceivers. 3. In the absence of good grounding measures, the SFP optical transceivers should not be inserted directly, which may lead to electrostatic breakdown of electro...
