4 Ch Mini HD-SDI Over Fiber Optic Extender

Extend four HD-SDI or SD-SDI digital video signals long distances over single-mode fiber optic cable

The Thor SDI to Fiber F-M4SDI-TxRx kit is a compact power house that will allow any user to transport four channels of 1.485Gbps HD-SDI Serial Data Interface over a single strand of fiber. Furthermore, this HD SDI over Fiber Kit of Transmitter and Receiver will send RS485 in reverse for easy control over the kit. This sturdy Fiber Extender creates an easy drop environment for users that require multiple HD-SDI sources on one Fiber across any application and even allows additional AUX Cards which can allow a plethora of other options such as RS232 and RS422, and even capable of carrying external analog audio instead of the SDI embedded audio. Thor Fiber has an excellent reputation as a Manufacturer of high quality and low cost price products to help complete your project on time, in a loss free high quality kit that will ensure you stay under budget. Our Fiber Optic Extender is Commonly used in security applications, live performance environments, video surveillance, SDI distribution and control in any environment. Our Unit supports 20km on a single mode and multimode fiber up to 3000 ft. This unit is an SDI over Fiber multiplexer and SDI over Fiber demultiplexer.

 

Locking Cables

ST or FC or SC fiber & BNC connectors make sure that the cable is not accidentally pulled out of the equipment 

 

 

 

 

 

No Link Alarms

Link status alarm on both the transmitter and receiver indicate when the link is not functional.

Serial Data

RS-485 return path sends serial data from the receiver back to the transmitter for device control.

Features
  • Supports 4 Full HD-SDI @ 1.5Gbps or lower SDI or ASI digital video
  • Transports embedded audio channels as well as SDI ancillary data
  • Return path serial RS-485 channel for controlling equipment on Tx end
  • Link alarm indicators on both Tx & Rx indicate a problem with the fiber

Question and Answers
Answer:
So the main difference is the multiplexing technology CWDM vs. TDM. The compact units utilize one laser to transmit the videos using TDM, which is a compression multiplexing method using time delay, and can result in very low signal delays up to 20ms. TDM is only Capable of transmitting up to HD-SDI 1.485Gbps. https://thorbroadcast.com/products/sdi-1 The CWDM units are uncompressed, utilize a laser per input source, and can go up to 3G-SDI with zero loss and delay. So the 4SDI Transmitter uses 4 lasers, which are then multiplexed via CWDM. These units are only made in rack mount chassis to accommodate the necessary internal hardware. Companies like NASA and the NHL use these models. https://thorbroadcast.com/products/sdi-sd-hd-3g-with-cwdm

1 SDI & HDSDI Over Fiber MINI Extender

(SD/HD-SDI coax-to-fiber) throw-down converter. Transmit multi-rate SD/HD-SDI video, up to 1.485Gb/s, at extended distances up to 80Km over one strand of single mode optical fiber, better than a rattler. F-M1SDI transmitter and receiver kit for transporting HD-SDI, SD-SDI, or DVB-ASI digital broadcast video signals over fiber cable. Provides 1 channel of RS-485 control data over a return path from the Rx back to the Tx.

1 SDI Tx with loop and Rx with 2 output over Fiber

The F-1MSDI-L-2TX is a mini Fiber Optic Transport unit that is utilized and extra loop out SDI connector on the transmitter for monitoring and for additional screening. The matching receiver F-1MSDI-L-2RX uses the same technology as the transmitter so you can actually have 2 SDI outputs on the receiving end of the Fiber. This allows for easy access to redistribute a primary Fiber Cable that needs to be split to two SDI outputs.
