● General Description:
ALTEK's Small Form Factor Pluggable (SFP) transceivers are compatible with the dimensions defined by the SFP Multi-Sourcing Agreement (MSA). The ALTEK Cisco compatible small form factor fiber optic transceivers are used in pairs. These transceivers transmit and receive signals on one fiber strand using two wavelengths. These hot pluggable optical transceivers consist of two sections: the transmitter section uses 1490 nm DFB laser/1550 nm Fabry-Perot laser; the receiver section uses an integrated B type/A type detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. The transceivers use standard simplex LC connectors for fiber cable connection and provide a long transmission distance of up to 80 km. In addition, the transceivers are compliant with SFP Multi-Source Agreement (MSA) Specification and SFF-8472.

● OEM & Customs:
Partnering with a variety of world class OEM manufacturers for over 8 years, ALTEK is able to provide customized high-quality and cost-effective solutions for all needs and specifications, including optical design, mechanical design, Printed Circuit Board (PCB) layout and electrical design, software & firmware design, integrated assembly, specific labels, etc. With surging sales and favorable customer feedback, ALTEK has been expanding rapidly across the world and is becoming the leading provider of the optical communication industry.
● Shipment:
ALTEK can ship via FedEx, DHL, UPS, TNT, EMS or a customer-arranged carrier. Items are often shipped the same day (some transceivers can be out the door in 20 minutes). If we have no stock in any of our global warehouses, the shipment will be delayed for 1-2 days. DHL will take 2-4 business days for delivery and FedEx only needs 1-3 business days. For Spain, Italy, Brazil and certain other countries, items will take longer to arrive due to the customs clearance period.
