25G SFP28 ER Transceiver

25G SFP ER transceiver is a single-mode extended reach transceiver. This SFP28 module is designed for duplex optical data communications to support 25Gb/s Ethernet with CDR engaged, while, 10G ethernet optical data communication can be supported when CDR is bypassed. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. This module is designed for single-mode fiber and operates at a nominal wavelength from 1295nm to 1310nm. The transmitter section uses a 1310nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825.

25G SFP28 CWDM Transceiver

25G SFP CWDM transceiver is a single-mode CWDM transceiver. It is SFP28 module for duplex optical data communications support up to 25.78Gb/s. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has a built-in clock and data recovery (CDR). This module is designed for single-mode fiber and operates at a nominal wavelength of CWDM (1271~1331nm).

25G SFP28 BiDi Transceiver

25G SFP BiDi transceiver is a single-mode Bidirectional transceiver. It is SFP28 module for duplex optical data communications supports up to 25.78Gb/s. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has a built-in clock and data recovery (CDR). This module is designed for simplex fiber and operates at a nominal wavelength of 1270 / 1330nm.

25G SFP28 DAC Cable

25G SFP28 DAC is a 25GBASE-CR direct attach copper cable for data center environment. It provides a high speed, cost-effective alternatives to fiber optics in 25GbE Ethernet applications. The cables are compliant SFF-8402 SFP28 standard. The 25G SFP cable is available in lengths up to 5m (16.4 ft) for passive DAC. Compared with SFP28 transceiver, 25G SFP DAC allows the customers to deploy the copper cabling with a far less budget.

25G SFP28 AOC Cable

25G SFP28 AOC is a 25GBASE-AOC SFP28 Active Optical Cables (AOC) taht designed for use in 25GbE Ethernet systems. The SFP28 AOC offers high port density and configurability, and reach much longer lengths than passive copper cables. It offers a cost-effective and power-efficient cabling solution for high-speed data applications.

Differences between cisco GLC-T and cisco GLC-TE

 Cisco GLC-T, GLC-TE and SFP-GE-T optical modules are all Gigabit port optical modules with RJ45 interface and 100m transmission distance. They are cost-saving solutions for Gigabit Ethernet connection in data center, access network and storage area network applications. Therefore, these three types of optical modules are often difficult to distinguish. In fact, the transmission effect of these three optical modules is the same, which optical module can achieve Gigabit transmission, but it is certainly noteworthy that the original Cisco GLC-T and SPF-GE-T optical modules were terminated on June 1, 2017 and replaced by GLC-TE optical module. SFP-GE-T optical module with NEBS 3 ESD function needs to be selected if it is traded directly with the telecommunications company (which requires NEBS).The price of GLC-T and GLC-TE optical modules is low, and they can also meet the needs of Gigabit Ethernet. The Cisco Gigabit optical modules provided by Easy Communications can meet a large number

Why the sfp transceiver not work

 The failure of the sfp optical module is divided into the failure of the transmitter and the failure of the receiver. Through the analysis of the main causes of the phenomenon, the most likely problems are mainly concentrated in the following aspects: The optical port of the  1000base SFP transceiver  is contaminated and damaged Because of the pollution and damage of the optical interface of the module, the loss of the optical link is increased, so that the optical fiber link is unreachable. The main reasons for this phenomenon are the following four points: 1. The optical port of the SFP optical module has been exposed to the environment for a long time, resulting in contamination and contamination of the SFP optical port; 2. The end face of the fiber jumper connected to the  Cisco SFP-10g-sr  optical module has been contaminated, and the SFP optical port provides been contaminated; 3. Improper operation of the end face of the optical connector with pigtails, scratching of the finish
