How to Ensure the Compatibility and Quality of 3rd-party Optical Transceiver?
When it comes to optical transceiver, as we all know there are 3rd-party optical transceiver and OEM (Original Equipment Manufacturers) optical transceiver. Literally, the 3rd-party optical transceiver is produced by a third-party optical transceiver manufacturer through independent analysis and decoding according to market specifications and standards. Many the 3rd-party optical transceivers are used by many users when they need a large number of optical transceivers to connect their devices. Because the excellent vendors can provide the compatible optical transceivers with a high quality, and the 3rd-party optical transceivers lower price than OEM optical transceivers.
However, how do you ensure the compatibility and quality of the 3rd-party optical transceiver? This is a problem that users need to consider when selecting the optical transceivers. This article can give you references to select the 3rd-party optical transceivers.
1. Is there a Data Diagnostic Monitoring Interface (DDMI) as defined by the SFF-8472 specification?
DDMI is also called DDM or DOM. DDM can monitor the condition of optical transceiver. Users can remotely monitor — in real-time — received optical power, transmitted optical power, laser bias current, transceiver input voltage and transceiver temperature of any transceiver in the network. These digital diagnostic functions provide network managers with a highly accurate, cost-effective tool for implementing reliable performance monitoring. The transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and alarm/warning threshold data is written during device manufacture.
1) Alarm flags associated with transceiver temperature, supply voltage, TX bias current, TX output power and received optical power as well as reserved locations for future flags. Alarm flags indicate conditions likely to be associated with an in-operational link and cause for immediate action.
2) Warning flags associated with transceiver temperature, supply voltage, TX bias current, TX output power and received optical power as well as reserved locations for future flags. Warning flags indicate conditions outside the normally guaranteed bounds but not necessarily causes of immediate link failures. Certain warning flags may also be defined by the manufacturer as end-of-life indicators (such as for higher than expected bias currents in a constant power control loop).
2. Compatibility Testing
The compatibility of the optical transceiver needs to be tested on the switch to check, this is the only way to ensure the compatibility of the optical transceiver.
The above references are the compatibility for optical transceivers. About the quality of the 3rd-party optical transceiver, you can verify from the testing process, shelf life, and supplier reputation.
How does Gigalight ensure the compatibility and quality of optical transceivers?
Gigalight has begun to deploy third-party compatible optical transceivers in 2006. Gigalight optical transceivers are widely compatible with all brands of device, switch compatibility testing will be carried out before shipment to ensure the compatibility of each transceiver. Basically, Gigalight optical transceivers are compatible with mainstream device vendors. Some device vendors have done encryption processing, and it is a little difficult to read the key information of DDM. This is also a key factor in compatibility.
Gigalight optical transceivers ensure compatibility and quality as following tests.
At the same time, Gigalight optical transceiver has the following compatibility test items and report abstract.
The quality of the optical transceiver directly affects the transmission effect. Gigalight optical transceiver has a price advantage while ensuring good compatibility and quality of the product, which can help users save a lot of cost.
