[Silvertel] 英商Silvertel 新品發佈 - Ag7200, 20W Isolated DC-DC Boost ConverterAg7200 - 20W Isolated DC-DC Boost Converter
The Ag7200 module is a low noise DCDC boost converter designed to generate the voltages required wherever an isolated 48V supply needs to be provided from a lower voltage e.g. for IEEE802.3 PSE, telecom or automotive applications. These modules provide exceptional efficiency (>90%) while providing full compatibility with the IEEE 802.3af power and isolation requirements and all in a low cost, compact SIL footprint package. With minimal extra components needed, circuit design is straightforward.
The module accepts a wide DC voltage input range, from 4.5V to 13V, providing added versatility. These input voltages are then boosted to generate the higher voltages required, for example, powering Silvertels’ Ag6100 or other compatible PSE circuits. Continuous power of up to 17W can be supplied, with a peak power capability of up to 20W. Ag7200 provides a regulated low ripple adjustable output, of either 48V or 57V.
The module uses a transformer to provide the necessary 1.5kV isolation between input and output connections to meet the requisite IEEE PoE safety and isolation requirements.
Ag7200 has been designed to provide an ideal solution for powering the Silvertel Ag6100 in POE 802.3af applications from a 5V on board supply, vehicle battery, 12V plug-top PSU or other commonly available power source. Its low cost, wide input voltage range, very small footprint, high efficiency and in-built isolation make it an extremely versatile DC-DC boost converter for a wide range of potential applications.

[Silvertel] 英商Silvertel 新品發佈 - 超迷你模組 Ag9924, 12W 24V Output POE PD ModuleAg9924 now released
Ag9900 offers a simple, ultra-small PoE solution using minimal external low cost components. External bridge rectifiers enable the device to be powered from midor end-span PSE, accepting power from the spare or data cable pairs. Operating over a wide input voltage range, the optimised DC/DC converter still has high efficiency (up to 87%). Built-in protection against overloads and short-circuits is also provided. The regulated DC output voltage is easily adjusted using a simple pull up/down resistor.
The Ag9924M provides signature and control circuitry to give full PoE compatibility. A signature is required by the Power Sourcing Equipment (PSE) before it will provide power to the port.
The industrial temperature Ag9924MT variant provides over temperature protection. This option reduces the output power if the maximum operating temperature is exceeded. Normal operation resumes when the temperature drops back below the threshold. Silvertel’s Ag9900 is ideal as a cost effective solution for POE for any application. This 24V output version caters for a growing trend towards 24V applications in access control, IP audio and industrial control.

[Eoptolink] 成都新易盛 新品發佈 - 25G SFP28 Transceivers25G SFP28 Optical transceivers
ChengDu, China -- Eoptolink (SZ: 300502) has released 25G SFP28 SR & LR transceivers.
Eoptolink EOLP-8525G-02-R & EOLP-1325G-10-RX, SFP28 optical transceivers are designed for use in 25G Gb/s data rate over multimode or single model fiber. They are compliant to IEEE 802.3by, SFF-8472 Rev 12.2 and SFF-8402, and compatible with SFF-8432 and applicable portions of SFF-8431 Rev. 4.1. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.
SFP28 is a 25GBASE interface which has evolved from 100 Gigabit Ethernet, which is typically implemented with 4 × 25 Gbit/s data lanes. Identical in mechanical dimensions to SFP and SFP+, SFP28 implements one 25 Gbit/s lane for top-of-rack switch to server connectivity. SFP28 may also be used to "break out" a single 100GbE port in a top-of-rack switch into four 25 Gbit/s individual server connections. SFP28 functions with both optical and copper interconnects.
