Product Overview

Double Fiber is part of the fiber optic media converter range built by Ever Expresslink Limited in Ningbo, China.

It is one of 8 items in this range. A typical application is consolidating converters into a rack chassis in a comms room. What the range is built to give you there: extends Ethernet well beyond the copper distance limit.

The problem it addresses is rack space consumed by dozens of standalone converters. A practical note that applies across this range: keep converters powered from a protected supply where the link is critical. Specifications for a particular configuration are confirmed on the quotation rather than assumed from the designation.

Key Benefits

Supplied as Double Fiber, so the part you receive matches the designation you ordered against
Single-fiber and dual-fiber versions to suit the fiber you actually have
Extends Ethernet well beyond the copper distance limit
Electrically isolates the two ends, removing ground loop and surge paths
Keeps existing copper equipment in service on a fiber backbone

Problems It Solves

Rack space consumed by dozens of standalone converters
Ethernet runs that exceed the copper distance limit
Electrical noise and ground potential differences between buildings
Legacy equipment with copper-only ports on a fiber network

Application Scenarios

Linking buildings on a campus over multimode or single-mode fiber
Extending CCTV to a remote gate or car park
Connecting industrial equipment across a noisy plant
Backhauling an access point or small cell

Who It Is For

Industrial and process control network integrators
CCTV and security system installers
ISPs extending service into premises
Enterprise IT teams linking remote plant

Use Guide

Handling Double Fiber

Before You Order

Match the fiber mode and wavelength at both ends before deploying
Use matched bidirectional pairs on single-fiber links; the wavelengths are complementary
Check the optical budget over the actual route, not the straight-line distance

In Service

Keep converters powered from a protected supply where the link is critical
Label both ends of the link with the converter pair reference
Verify at full line rate, not just link-up, before handing over

FAQ

Questions About Double Fiber

What do you need from us to quote Double Fiber?

The quantity, the destination and anything that has to match on your side: connector and polish at each end, fiber mode and core size, and length where the item is an assembly. If you are matching a part you already buy, send the sample and we will quote against it.

How far will a media converter reach?

It depends on the optics, the fiber mode and the loss of the actual route. Tell us the distance, the fiber type and the number of connectors and splices and we will confirm which version has the budget for it.

Do SFP-based converters give more flexibility?

Yes. With SFP slots you choose the optics separately, which lets one converter model cover short multimode links and long single-mode spans, and lets you change reach later without replacing the converter.

Can converters be rack mounted?

Yes, chassis versions consolidate multiple converter cards into a single rack-mounted unit with shared power, which is normally what you want above about six links.

Do converters need configuration?

Standard units operate without configuration. Confirm duplex and speed settings on the equipment they attach to, since a mismatch there is the most common cause of a link that comes up but performs badly.
