This latest installment in the Technology Trends series by Bob Hult examines the trends and technologies that have pushed copper to the limits and ushered in fiber optic cables.
Are expanded beam connector systems an alternative to the MTP®/MPO connector? Check out Rosenberger’s White Paper to learn about the requirements placed on multifiber connectors and what is needed to ensure uninterrupted, high data transmission rates.
Multi-fiber push on connectors (MPO) are a single connector that houses multiple fiber terminations, defined by IED=61754-7.14. The MPO’s rise in popularity is due to it’s ability to mate multiple fibers (2-72) within a single connector body, thereby significantly reducing the space needed.
Watch this webinar from Senko’s Tiger Ninomiya on demand and learn about the evolution of fiber optic connectors in data centers.
This on-demand webinar discusses the importance of inspecting and cleaning the connector end-faces, the approval/rejection criteria defined by the standards, as well as methods to maintain clean connectors.
Amphenol Network Solutions’ Layered Fiber Demarcation box is designed for high-density fiber connectivity and splicing for indoor wall mount applications. This product can be made even more efficient with the addition of Multi-fiber Push-On (MPO) Cable Assemblies that deliver a Plug-n-Play solution for interconnecting elements in an optical network. The MPO connectors provide a quick and reliable link for multiple fibers (e.g., 12) in a single industry-standard connector.
The SN connector is a new, duplex optical fiber connector using LC style 1.25mm O.D. Zirconia ferrules, designed for next generation hyperscale data center interconnect (DCI). This connector was designed to provide individual and independent duplex fiber breakout at a quad style transceiver (QSFP, QSFP-DD and OSFP) that Senko contends is not only more efficient, reliable and scalable than the MPO connector but also at a lower in cost to implement. The SFP-DD has also adopted the SN as their independent duo style interface, mainly for the wireless fronthaul applications.
Rosenberger has achieved excellent return loss values with APC 8° angled polish of multimode MTP®/MPO connectors. The APC 8° angled polish is used from the outset for singlemode MTP®/MPO ferrule endfaces to achieve reliable return loss. In contrast to this, only the PC 0° straight polish was previously used for multimode MTP®/MPO ferrule endfaces. Due to their PC 0° straight polish design, multimode MTP®/MPO connectors were previously particularly susceptible to performance problems caused by dirt particles, which in the past often led to unreliable return loss values.
Fiber Optic Connectors need to be pristine when they are connected for several reasons. First, dirty or damaged connectors are the number one cause of network outages. Second, if a dirty or damaged connector is plugged into another connector, your problem just doubled. Lastly, if test equipment, like an OTDR, or a network element, such as a receiver, is damaged it can cost hundreds or thousands of dollars to repair or replace them.
85% of network failures are caused by dirty connectors. The connectors entrusted to carry the critical information that passes through your network deserve far more than a wipe on a t-shirt. As data center bandwidth continues to increase, adherence to best practice fiber endface cleaning and inspection methods must improve. Download AFL’s best practices guide for cleaning.
