Superior Performance

The BlueOptics© BO28C4334620D Dual Bidi Compact Small Form-Factor Pluggable (cSFP) transceiver with LC Duplex connector from CBO is designed for long-range single-mode Gigabit Ethernet (GbE), Gigabit Fibre Channel over Ethernet (Gb FCoE) or OC-24/STM8 SDH/SONET high-speed applications of up to 1.25 gigabits per second.

Wide Range of Applications

Unlike traditional Duplex Bidi transceivers with only one laser, the BlueOptics BO28C4334620D Dual Bidi cSFP transceivers have two installed (BOSA) lasers, which provide a combined receive and transmit function for optical signals via single mode fiber, regarding the respective gigabit protocol, such as the GB Ethernet 802.3z standard. BlueOptics BO28C4334620D Dual Bidi cSFP modules are suitable for the use in switches, routers, storage systems and other hardware in the second and third optical window at 1310nm and 1490nm.

Wide Range of Applications

Double your Bandwidth

Double your Bandwidth

Increasing the bandwidth for the same installation with BiDi technology. Bidirectional Wavelength Division Multiplexing, a WDM technology offers the possibility of data transmissions over a single optical fiber. For this purpose, transmitted and received data is transferred on two different wavelengths.

Error Analysis with Digital Diagnostics

Facilitate troubleshooting, maintenance and monitoring in your network through the Digital Diagnostics Monitoring (DDM) / Digital Optical Monitoring (DOM) interface. Using the digital diagnosis function, compliant with MSA SFF-8472, BlueOptics BO28C4334620D Dual BIDI cSFP transceivers provide real time information like Supply Voltage, Laser Bias Current, Laser Average Output Power, Laser Received Input Power and Temperature.

Maximum Availability

Maximum Availability

Less maintenance due to a long lifetime. BlueOptics BO28C4334620D Dual BIDI cSFP transceivers only use components of leading manufacturers for Lasers (i.a. Lumentum, Avago, Mitsubishi, Sumitomo) and Integrated Circuits (i.a. Maxim Integrated, Netlogic, Mindspeed, Analog Devices). BlueOptics BO28C4334620D Dual BIDI cSFP transceivers are designed for an above-average operating time of approximately 3.000.000 MTBF hours.

5 Years Warranty for BlueOptics
Each BlueOptics BO28C4334620D Dual BIDI cSFP transceiver is covered by a 5-year function warranty by CBO.

Lifetime Support
For the lifetime of the product you receive technical support via email and telephone.

Next Day Exchange
The CBO preliminary exchange encompasses free shipping of replacement modules on the next working day.

Full MSA Compliance

BlueOptics BO28C4334620D high availability Dual BIDI cSFP transceivers meet the Multi Source Agreement (MSA) standard. With MSA Standards various manufacturers determine standardizations of the transceiver to ensure the interoperability. Here the Dual BIDI cSFP interface is defined electrically, mechanically and functionally.

Full MSA Compliance

Industrielle Normen

Industrial Standards

BlueOptics BO28C4334620D high availability Dual BIDI cSFP transceivers meet or exceed industrial standards, such as CE and RoHS as well as the regulations of the FCC.
