TRANSCEIVERS AND OPTICAL COMPONENTS

Transceiver Modules: Arvensis Consulting has direct access to world leading manufacturers for supply and distribution of transceivers and passive optical solutions. This enables us cut out the middle man and obtain exclusive pricing. We are also able to facilitate between a customer and the manufacturer’s R&D teams for specific requirements that may warrant R&D interaction.

Arvensis Consulting have direct  agreements in place with manufacturers for multi-mode (MF) and single-mode (SM) transceivers, ranging from 1Gb up to 400Gb with a combination of 9dB to 23dB power output options.s.

Specialised optics for CWDM, DWDM, Bidi and SDI video and legacy CMI STM-1 electrical modules are also available.
Coherent optics for DWDM long-haul are also available however this is POA and subject to customer requirements.

​Passive optical xWDM solutions with a MTBF of ~500 years for 2 to 8 channel CWDM products and 32 to 96 channel for passive DWDM solutions.
A typical 8 channel CWDM solution will realise an annual saving of $30k (based on a single metro fiber with a monthly cost of $355 and excl equipment costs). Greater saving can be realised with the 12 and 18 channel units

User Cases for CWDM

Cost savings that can be realised is linear against current fiber rental costs so the more fiber connections you have in place between 2 locations, the more savings you can realise.
This is not however limited to dark fiber access services as the same can be applied to leased Layer-2 services or any connectivity in fact.

Arvensis Consulting can assist you with input for your business case, help model your current costs against a design solution to achieve the maximum potential savings.

Payback = Return On Investment. Guaranteed to keep any CFO happy when it comes to Capital investment.
Some examples of payback time, measured in months:

  • 2x 1Gb – 10 months
  • 2x 10Gb – 18 months
  • 4x 1Gb – 4 months
  • 4x 10Gb – 10 months
  • 5-8x 1Gb – 3 months
  • 5-6x 10Gb – 8 months
  • 7-8x 10Gb – 7 months
  • 9-12x 1Gb – 2 months
  • 9-11x 10Gb – 7 months
  • 12x 10Gb – 6 months
  • 12-18x 1Gb – 2 months
  • 12-18x 10Gb – 6 months

Arvensis Consulting also supply optical patch cables in any configuration and to specification in accordance to the IEC Grade-C and high spec low insertion loss Grade-A (-0.07dB to -0.15dB) as well as optical attenuator’s for various connector types.
Typical Grade-C, off the shelf optical patch cables have an insertion loss between -025dB to -0.50dB.

If you are in a jam with miss-matched connectors, we can also supply hybrid couplers to mate various connector types such as LC/SC, LC/FC, FC/ST, FC/SC, SC/ST and other configurations. (Availability may be limited and subject to lead times of 5-7 days. Priority shipping fees may apply if urgent as these are not commonly ordered products)

Arvensis Consulting stock LC and SC optical attenuators for 1, 2, 3, 5, 8, 10, 15, 20, 25db variants in both APC and UPC finish. Stock is limited but we can land an order 7-15 business days from order or sooner for priority orders

Compatible Optical Transceivers

Arvensis Consulting sources MSA compliant transceivers direct from our partner who manufacturer their own transceiver. We do not source from wholesalers or distributors but direct from factory. This provides Arvensis Consulting with access to our manufacturers R&D team and well as being able to provide feedback directly to the engineering teams .

MSA standards are in place for all pluggable form factors including SFP, SFP+, XFP, XENPAK, QSFP, QSFP28 and CFP. The standards themselves define characteristics such as mechanical interface, electrical interface, and additional features such as digital monitoring DDI/DOM. The standards also set forth a precedent for the Electrically Erasable Programmable Read-Only Memory (EEPROM). The EEPROM memory is defined within the MSA standards including the optical transceivers capabilities, interfaces and also the name of the vendor.

Compatibility is generally controlled by means of vendor codes, which are characters stored within board chips, that are used to identify compatible hardware. If the transceiver returns an incorrect code then the host device will not recognise it and refuse to operate or issue a warning. Such mechanisms have generally been used in order to lock in the customer to a premium priced product and subvert the standardising value of the MSA's.

By law, vendors cannot stipulate that only branded parts may be used within the target system in order to retain warranty validity. The threat of void warranty is a commonly sold misconception designed to protect the vendor’s sales channel and is almost never available in writing. In general, such mechanisms have been unsuccessful and no longer function as a barrier to entry to the market.

These types of warnings by OEM do exist. They are seldom made in writing and are widely held to be unenforceable. Our understanding is that custom and practice today is that warranty or support will not be withheld unless the compatible transceiver can be proven to have caused a defect, which is more or less unheard of. In any case, today operators routinely ask system vendors to certify the use of quality compatibles from reputable and professional suppliers.

The use of MSA compliant optical transceivers does NOT void your equipment warranty
