Custom 200GBASE-ER4 CFP2 Optical Transceiver

Product Description

Telecom carriers operating legacy core routers and dense OTN transponders require optical modules that match their heavy-duty chassis specifications. The Custom 200GBASE-ER4 CFP2 module fulfills this necessity. Unlike compact data center form factors, this transceiver utilizes its substantial physical footprint to aggressively dissipate the heat generated by 40km-rated optical engines. OEM configured by WolonFiber engineers, this unit provides the ultimate path for network providers upgrading massive metropolitan rings without replacing their multi-million-dollar host hardware.

Key Features

• Dual-Rate EEPROM Provisioning: Capable of being factory-coded to support standard Ethernet (212.5Gbps) or OTN framing protocols, maximizing deployment flexibility.

• Chromatic Dispersion Resistance: The integrated DSP actively compensates for the optical wave spreading inherently caused by forcing PAM4 signals across 40km of silica glass.

• Hot-Pluggable Durability: Designed with reinforced edge contacts specifically rated for thousands of insertion cycles in harsh carrier-hotel environments.

Application Scenarios

• Upgrading line cards on legacy optical transport wave-division multiplexing (WDM) systems.

• Cross-city dark fiber links requiring extreme environmental tolerance and high thermal redundancy.

Engineering FAQs

• Q: Why deploy a cfp2 200g module when a QSFP56 ER4 accomplishes the same distance?

  A: Transceiver selection is dictated by the port architecture of the host equipment. Many heavy-duty telecom line cards natively feature CFP2 slots precisely because their immense metal chassis can safely dissipate the 14W thermal loads generated by 40km+ optical engines, offering higher MTBF (Mean Time Between Failures) than QSFP equivalents.

• Q: What is the MDIO interface listed in the specifications?

  A: The Management Data Input/Output (MDIO) bus is an IEEE standard serial interface utilized on CFP/CFP2 modules. It provides significantly more robust and complex hardware control and monitoring capabilities than the simpler I2C interface used on QSFP form factors.

• Q: Can this transceiver be deployed in a 100G CFP2 slot?

  A: No. While physically identical, the electrical ASIC connecting the slot must be capable of processing the 200G electrical signals. A 100G switch backplane cannot negotiate with a 200G optical module.
