At Rancent we sell our products and services to distributors, integrators, and OEM partners. We aim to stay behind and create the best value for our partners in terms of quality, price and performance. Rancent is already a supplier to some local distributors and we are always glad to work closely with you in providing high-quality connectivity and CCTV solutions. Contact us via email@example.com or firstname.lastname@example.org for more information or any inquires.
All Rancent products ship from our warehouse and manufacturing facilities located in Tianjin, China.
Rancent warrants to the customer that our products will be free of defects in design, materials and workmanship under normal use for a period of three years from the date of delivery. Please follow this link to our Warranty Information page.
Rancent has been in business over 15 year since our establishment in 2003.
Rancent has a R&D team of innovative and highly skilled engineers dedicated to the continual improvement of existing products and the development of customized products responding to customer’s needs.

Our printed sales literature can be shipped within a few days of your request. If you need it faster, every piece is available as a PDF that can be sent to you via email. Send your request to firstname.lastname@example.org.
Please email your official orders with detailed product and shipping information to email@example.com.
Normally the order for standard products will be processed 4-6 business days to be ready for delivery. We use UPS, DHL or TNT to facilitate the delivery of small quantity orders to overseas customers. The delivery time will be 3-5 business days depending on the destination after the order leaves our facilities. For larger quantity orders, we work with the freight forwarder authorized by us or customer for the delivery of shipment.

Secure communication – no risk of information leaking
Low installation cost and easy future expandability
Multimode fiber has a relatively large light carrying core, usually 62.5 microns or larger in diameter. It is usually used for short distance transmissions with LED based fiber optic equipment. Single-mode fiber has a small light carrying core of 8 to 10 microns in diameter. It is normally used for long distance transmissions with laser diode based fiber optic transmission equipment. Here are the main differences:
*Rancent Ethernet/Video over Fiber Multimode products are compatible with OM1, OM2, OM3 & OM4 multimode fiber.
This depends on the application. Multimode fiber will normally allow transmission distances of up to about 3 km and will allow the use of relatively inexpensive fiber optic transmitters and receivers. There will be bandwidth limitations of a few hundred MHz per Km of length. For CCTV this will be fine but for high speed data transmission it may not be.
Singlemode fiber on the other hand will be useful for long distance transmission from 20 km to 120 km but will require the use of singlemode transmitters (which normally use solid-state laser diodes). The stricter requirements of the small core size of singlemode fiber and the higher cost of these optical emitters mean that single-mode equipment can be relatively more expensive. Also singlemode optics may be compatible with multimode fiber cable but multimode optics are not compatible with singlemode fiber cable.
Multimode fiber optic transmitters and receivers allow transmission distances from 500 m to 5 km depending on different models while singlemode converters are designed to extend the distance over single core fiber up to 120 km (Other distance options of laser diode modules are 20/40/60/80/100 km).
Rancent product line has a variety of different fiber optic transmitter and receiver options available, allowing users to choose the correct product for each application in order to provide the required optical connectivity solution over fiber when fiber is chosen. The selection of the correct model needs to confirm several factors including fiber type (singlemode or multimode), channels over fiber (video/data/audio/contact closures/Ethernet), fiber connector, transmission distance, power supply voltage, plug types and standalone or rack mountable versions, etc. Send your inquiry to firstname.lastname@example.org for further discussion and confirmation.
