Fiber Optic Connector BF4-IR2LCD-01-2M – Hirose Electric Co. Ltd.

The bidirectional transmission active optical connector BF4-IR2 has been developed for internal and inter-devicewiring.

Active Optical I/F Connector

Report Abuse


Incorporating two BF4MC Series connectors inside the plug enables bidirectional transmission, significant lower
use of power consumption than conventional optical transmission modules, and an interface with flexibility superior to
conventional optical fiber cables. Furthermore, BF4-IR2 is a dual core optical I/F connector that allows long distance
transmission, electromagnetic noiselessness and isolation, all of which are merits of optical transmission.


Mating Durability of 1,000 Cycles

Unlike conventional optical connectors,
the BF4-IR2 Series is an active connector
(electrical connection) and has a robust design
for a mating durability of up to 1,000 cycles like
other Hirose interface connectors.

Built-in LED for Connection Confirmation

The built-in LED (Amber/Green) allows for
operation check (control confirmation) from
outside the connector.

Bending Durable 2 Core Fiber

BF4-IR2 uses the same flexible fiber as BF4MC.
The minimum recommended bending radius is R10.

Low Power Consumption

Two BF4MC inside the BF4-IR2 enable low power

Hirose will connect wisdom by thinking small, create new value, and contribute to the development of a global society.

“The principle of ‘being small’” represents our aspiration that we should always consider ourselves small and remain a company with great potential. On the other hand, “connecting wisdom” represents our desire to absorb external knowledge and wisdom with honesty and humility, translate them into excellent original products by connecting them with our own internal knowledge and wisdom, and then provide such products to the world. In this way, we intend to produce even greater results as a means of realizing the aspiration described above.

With these basic principles, we aim to develop, manufacture, and distribute excellent connectors that can, with their “connecting” function, bring different parts and products — which are themselves crystallizations of people’s wisdom — together, produce various new products, and contribute to the development of a global society.
