The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 550m transmission distance with MMF.
The transceiver consists of three sections: a VCSEL lasertransmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

Notes:
1. The optical power is launched into MMF.
2. PECL input, internally AC-coupled and terminated.
3. Measured with a PRBS 27-1 test pattern @1250Mbps, BER =1x10-12.
4. Internally AC-coupled.
RETURNS POLICY
To return goods we have delivered to you, please contact us within 30 days from the date you have received the item. A staff member will then assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be sent for repair, or providing you with a replacement.

Faulty Items
We recommend you immediately inspect any goods that we deliver to you or that you collect from our store to ensure you are completely satisfied with the goods. If any goods arrive damaged, please contact us as soon as possible. We will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund. Replacements and refunds of new products that are damaged on delivery or faulty from new requires a proof of purchase of the product and be returned with all original packaging, accessories and/or manuals included. Refunds will be made via the method of payment you used to make your purchase. If we consider the goods to have breached a consumer guarantee, any shipping costs to return the goods to us will be at our cost and compensated.
Repairs
The product must be returned with proof of purchase, it must not be modified or mistreated in any way and it must not have been serviced elsewhere. Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident. We may provide you with an approximate fee; this may vary due to reasons beyond our control. In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
