EFB-Elektronik O0937.2 — Duplex Patch Cable E2000/APC to LC, OS2, 2 m, Yellow

E2000/APC ↔ LCOS2 single-mode 9/1252 m · duplexG.657.A1 · LSZH

The EFB-Elektronik O0937.2 is a 2 m duplex single-mode fibre patch cable with E2000/APC connectors on one end and LC connectors on the other. It is the typical cord for connecting an E2000/APC patch panel or provider handover — common in European FTTH and carrier installations — to LC ports on switches, SFP modules or media converters.

It uses OS2 9/125 fibre to ITU-T G.657.A1, which tolerates tighter bends than standard single-mode fibre, inside a 3 mm yellow LSZH jacket with aramid reinforcement. Insertion loss is specified at 0.25 dB or less and return loss at 45 dB or more at 1310/1550 nm, and every cable comes with its own measurement report and duplex clips.

Before you order: One end is E2000 with APC (angled, green) polish: it must mate with an E2000/APC adapter — never with E2000/UPC (blue), which damages both end-faces. The LC end goes into standard single-mode LC ports. This cable is single-mode only; it will not work with multi-mode equipment.

What's in the Box

  • 1 × EFB-Elektronik duplex patch cable E2000/APC–LC, OS2, 2 m
  • 2 × duplex clips
  • 1 × measurement report (test protocol)
  • 1 × information sheet, in a resealable bag

What It Means in Practice

  • Typical use: from an E2000/APC fibre termination box or ODF to the LC SFP of your router, switch or ONT.
  • The factory test report documents insertion loss, which helps when you need to prove a link budget.
  • G.657.A1 fibre handles tighter routing in cabinets and cable managers with less bend loss.
  • The duplex clips let you join or split the two fibres — useful if TX/RX need to be swapped.

What Will Not Work

  • It will not mate with E2000/UPC (blue) adapters — APC and UPC must never be mixed.
  • It will not work on multi-mode (OM1–OM5) links.
  • It does not have SC or ST connectors — use the matching variant for those ports.
  • It is a 2 m cord; the length is fixed.

Frequently Asked Questions

How do I tell APC from UPC?
By colour: APC connectors and adapters are green, UPC are blue. This cable's E2000 ends are APC (green) and must go into green E2000/APC adapters.
Is the LC end APC too?
EFB-Elektronik lists only the E2000 end as APC; the LC end is the standard type used in SFP ports and LC panels.
Do I need to swap TX and RX?
If the link does not come up, swap the two fibres at one end — the duplex clips can be opened to do this.
Singular Expert Insight · Buyer's Guide
E2000/APC to LC is one of the most common cords in fibre-to-the-building installations: the provider terminates in E2000/APC, your equipment uses LC. Order the APC version that matches the panel, and connect the LC end to your switch SFP ports or ONT.
✓ Buy it if you need to connect an E2000/APC single-mode panel or handover to LC equipment ports.
✕ Skip it if your panel is E2000/UPC (blue), SC or LC, or your link is multi-mode.
→ Also consider Other lengths of the same EFB-Elektronik E2000/APC–LC OS2 series (0.5 m to 40 m).
Send us a photo of the panel adapter and the device port and we will confirm the right connector and polish before you order.
