OFNP vs. OFNR

Fiber optic cables are a vital component of modern communication networks. They are used to transmit data over long distances with minimal signal loss and interference. Two common types of fiber optic cables are OFNP (plenum) and OFNR (riser). Understanding the differences between these two types of fiber optic cables is crucial in making the right choice for your communication network.

OFNP (Optical Fiber Non-conductive Plenum) cables are used in air-handling spaces and plenum areas in buildings. Plenum areas are those spaces that allow air circulation for heating, ventilation, and air conditioning (HVAC) systems. OFNP cables are made of fire-resistant materials and are required to meet strict fire safety codes. They emit low levels of smoke and toxic fumes, making them suitable for use in areas where smoke and toxic fumes could be dangerous in the event of a fire.

OFNR (Optical Fiber Non-conductive Riser) cables, on the other hand, are used in vertical risers or pathways in buildings. They do not emit low levels of smoke and toxic fumes and are not required to meet the strict fire safety codes of OFNP cables. OFNR cables are less expensive than OFNP cables and are typically used in non-critical areas where fire safety is not a major concern.

When it comes to transmission performance, they are identical. They both offer high bandwidth and low signal loss, making them ideal for transmitting large amounts of data over long distances. However, OFNP cables are typically more expensive than OFNR due to the compounds used in the manufacturing process for the outer jacket. 

In conclusion, the choice between OFNP and OFNR fiber optic cables depends on the specific requirements of your communication network. OFNP cables are ideal for use in air handling spaces and plenum areas where fire safety is a concern, while OFNR cables are suitable for use in non-critical areas where fire safety is not a major concern. OFNP cables can always be used in place of OFNR, but not vice versa. 

Different types of optical fiber cables exist for various fire ratings, which can make choosing the appropriate one a challenging task. To aid those who are planning or installing a fiber network, UL 1651 is a critical guideline for ensuring the correct selection of fiber. The National Electric Code (NEC) Article 770.19 outlines these guidelines, but some commonly used measures include:

  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for small, in-building deployments using a riser
  • OFNP, OFCP for existing fabricated ducts within a building
  • OFNP, OFCP for plenum spaces used for environmental air in public buildings
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for fireproof shafts using a riser in any building type
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC when using a metal raceway for in-building deployments covering multiple floors and rooms/apartments
  • OFNP, OFCP, OFNR, OFCR for vertical runs between floors within a riser
  • OFNP, OFCP, OFNR, OFCR for riser cable routing assemblies inside a building
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for in-building deployments with routing on only one floor.

EDC of Sarasota County Economic Outlook Luncheon 2022

“DMSI is a unique company in every aspect of the word ‘unique’. We are visionaries; a company built by people who are dedicated and determined to not let the things we do not have determined by the possibilities of what we could have.” — DMSI International CEO, Jeneth D’Alonzo

SARASOTA – On May 20th, our CEO Jeneth D’Alonzo was invited to be one of the two keynote speakers at the Sarasota Economic luncheon at Hyatt Sarasota. She gave a heartfelt and wonderful speech before over 500 attendees.

Also at the event, Jeneth was able to meet our U.S. Congressman Greg Steube.

Some of the DMSI family were in attendance as well supporting our CEO’s speaking engagement and understanding the thriving economy of Sarasota County therewithal.

MDC (VSFF) connector supports all 3 IEEE 802.3db Use Cases

Current duplex connectors do not support 4 duplex connectors in a single QSFP-DD package and 2 duplex connectors in a single SFP-DD package. A smaller format duplex connector is needed to support QSFP-DD/OSFP 4:1 and SFP-DD 2:1 breakout applications.

MDC (Very Small Form Factor) connectors support these new breakout applications and allow four connectors to be fitted within the QSFP-DD module, which LC duplex connector cannot accomplish.

The MDC connector is a Very Small Form Factor (VSFF) duplex optical connector designed for termination of single-mode and multimode fiber cables up to 2.0mm in diameter. It is a 2-fiber connector using proven 1.25mm LC ferrules, providing 3x density over LC. Adapters use the same port cutouts and sizes as LC, allowing current designs to transfer from LC to MDC. MDC solutions include uniboot style jumpers, harnesses, trunks, panels, and many pre-terminated MTP® options.

For high density data centers application, DMSI designed and engineered OMNIA® Next Generation MDC Solutions for guaranteed exceptional optical performance and optimal stability exceeding the requirements of Telcordia GR-326. (https://www.dmsimfg.com/mdc/)
