Custom 100G CFP & CFP2 Optical Transceivers (Carrier-Grade)

Product Description

Core transmission platforms utilized by legacy telecom operators often feature interface slots built to the ruggedized CFP or CFP2 standard. WolonFiber’s custom 100G CFP/CFP2 transceivers are explicitly manufactured for these heavy-duty routing chassis. The voluminous housing easily accommodates complex Semiconductor Optical Amplifiers (SOA) and high-draw Thermo-Electric Coolers (TEC). Whether bridging 10-kilometer municipal aggregation nodes or completing 80-kilometer inter-provincial runs, these modules sustain near-zero bit error rates under extreme continuous thermal loads.

Key Features

• LAN-WDM Core: Houses 4x 25G LAN-WDM transmitter arrays (1295-1309nm) to drastically restrict chromatic dispersion across long single-mode runs.

• Optimized Receiver Matrix: Scientifically pairs PIN detectors for short/medium spans and Avalanche Photodiodes (APD) for extended reaches, guaranteeing flawless signal reconstruction.

• CapEx Protection: Delivers immediate bandwidth multiplication for operators unable to financially justify entirely replacing their legacy core chassis infrastructure.

Application Scenarios

• Interconnecting legacy telecom core routers with modern OTN Wavelength Division Multiplexing platforms.

• Long-haul, direct optical links for enterprise disaster recovery centers requiring extreme thermal redundancy.

Engineering FAQs

• Q: Why procure large CFP/CFP2 modules instead of the more compact QSFP28?

  A: Transceiver selection is dictated by your host chassis hardware. Many core telecom line cards (such as heavy OTN platforms) natively require CFP/CFP2 slots to support the massive cooling requirements of 80km/100km transport lasers.

• Q: Are CFP and CFP2 transceivers physically interchangeable?

  A: No. CFP is the first-generation 100G form factor, drawing up to 24W. CFP2 is the next iteration, offering half the physical size and capping power draw around 12W. The interface pins are not compatible.

• Q: What is the primary function of the OTU4 protocol in the Dual-Rate module?

  A: OTU4 (111.8Gbps) is a telecom-grade transport protocol featuring complex overhead framing and heavy Forward Error Correction (FEC). Dual-Rate modules allow the optic to bridge standard Ethernet environments with specialized carrier Optical Transport Networks.

• Q: Do ER4/ZR4 variants of CFP/CFP2 require optical attenuation testing?

  A: Yes. Because they utilize highly sensitive APD receivers, performing a loopback test or short-cable connection without at least a 10dB inline attenuator will permanently burn out the photodiode.
