## Description

desertcart.com: Single Mode SC WDM Single Fiber Bi-Di Gigabit Ethernet Media Converter Pair | 2 units, A+B sides 1310/1550nm - ONE fiber strand, simplex SC/UPC blue RJ-45 UTP Cat5e Cat6 RJ45 10/100/1000 auto sensing : Electronics

Review: Speed as advertised - Was not familiar with this company but was looking for a device to replace a 100 fdx device in order to achieve gigabit speed over single mode simplex fiber (device I replaced was Planet Fast Ethernet Bridge 10/100Base-TX). If you are looking for a solution outside of an sfp module, I recommend this device. Ran several tests over the fiber link and I was consistently receiving just under 900 Mbps with little to zero packet loss. The test I was using was a powershell script that would write a dummy file to a mapped drive on the other end of the fiber. To make sure the 900 Mbps was a hard drive limitation and not a bottle neck at the media converter, I ran the same test on the same network segment (not going through the fiber) and the results were comparable. Compared to the media converter it replaced, it runs cooler and seems to use less power which surprised me considering the speed advantage. The only semi negative thing I can find about the device is that I am not sold on the inline power brick as opposed to the power brick being on the charger port. It's not a major issue, just requires little work to tidy up the installation.
Review: So simple - These things just work. Quick and reliable set up. I used these to network my shop to my house.

## Features

- 1000BASE-LX WDM BI-DI OVER A SINGLE STRAND, SC/UPC - Transmit and receive are wavelength-multiplexed onto one fiber: 1310nm in one direction, 1550nm in the other. Full-duplex 1 Gbps, 20 km (12.43 miles) over OS2 9/125 single-mode. Optical bulkhead is SC simplex, UPC polish - the flat-polished blue-bodied type. An APC ferrule is cut at 8 degrees and cannot couple to a flat UPC endface, and a duplex connector body will not mate with a simplex bulkhead. The patch cord to order is SC/UPC simplex single-mode.
- FULL-DUPLEX GIGABIT ON A SINGLE STRAND - A SIDE 1310/1550, B SIDE 1550/1310 - Opposing wavelengths carry the two directions simultaneously, so the link runs 1000 Mbps full duplex in both directions at once - the same throughput as a two-strand pair, over half the fiber plant. Unit A transmits 1310nm and receives 1550nm; unit B is the inverse. One of each terminates a link and both ship in this box.
- RJ45 10/100/1000BASE-T AUTO-NEGOTIATING, AUTO MDI/MDI-X - Copper port auto-negotiates 10Base-T, 100Base-TX and 1000Base-T against switches, routers, access points and NVRs. Cat5e or Cat6 UTP. Compliant with IEEE 802.3, 802.3u, 802.3z, 802.3ab and 1000Base-LX WDM BiDi.
- 9000-BYTE JUMBO FRAMES, QinQ AND 802.1Q TRANSPARENT - MTU carries stacked VLAN tags intact, so the link passes a tagged trunk without stripping or re-writing. Jumbo frame support and LLF link-loss forwarding are each selectable on the rear DIP block.
- SUPPLIED AS A COMPLETE LINK - Two converters (A side and B side), two 100-240 VAC power adapters, a Cat6 patch cable, wall-mount ears and rubber feet. Both terminations in one box. External requirement is one simplex single-mode strand between the two units and an SC/UPC simplex patch cord at each end.
- 20 KM / 12.43 MILES, 0 TO 70 C, FANLESS - Optical budget reaches 20 km on OS2 9/125 single-mode. Operating range 0 to 70 C (32 to 158 F), relative humidity 5 to 90 percent. 94 x 70.5 x 26.5 mm per unit. Status LEDs per unit: Power, Link/Activity, Full-Duplex, Speed.

## Questions & Answers

**Q: Why is one unit of the pair labeled "A" and the other labelled "B"? Is there a difference between the two units?**
A: Yes, these are sold as a pair, and pair consists of A and B units, and this is how they must be used - A in pair with B - because these WDM - Wave Division Multiplexing type units, that uses only 1 fiber to communicate with each other, and thus, A side will use 1310/1550nm and, B side - opposite of 1550/1310nm wavelength division. This is how these particular single fiber WDM units work

**Q: Anyone have a 450 ish ft patch cable that they can recommend? Doing a run through buried conduit.**
A: We have used some of the products from Fiber Cable Direct Store. Various lengths. So far, they have performed well. Be careful of snagging the connectors as we pulled a connector off on one pull.

**Q: hola no se mucho del tema, pero necesito una solución para que un local que esta a 200metros tenga internet de un moden lan. ¿esto es viable ?**
A: si con este equipo puede mandar internet a mas de 5 km de distancia atravez de una cable de fibra optica

**Q: Will this support full hd? will it support bidirectional communications with an ip pan/tilt/zoom camera?**
A: Typically full hd cameras will not consume more than 24mbit/s bandwidth, and since these are 1G (1000mbit/s) converters it is more than enough. But one thing you need to note, that these are non-poe media converters, so they will not power up camera via same rj-45 cable - power needs to be supplied separately

### ⭐⭐⭐⭐⭐ Simple and easy installation
*by J***U on February 23, 2022*

The pair of units were tested with a single optical fiber. Within seconds the communication was established at 1Gbits/seconds. The units are compact, low power and have good shielding. No EMI were detected outside the enclosures. I used a 5 Meters SC to SC Fiber Optic Cable Single-Mode for this test. I recommend the product and customer service has been responsive to my inquiries.
